How to Root Samsung Galaxy S8 Snapdragon Variant using Extreme Syndicate Root Method

How to Root Snapdragon Galaxy S8

This step-by-step guide will instruct you on how to root Galaxy S8 Snapdragon with V7 bootloader, using the new Extreme Syndicate root method. The method is compatible with SM-G950U and SM-G950U1 models sold in the US.


Samsung has been consistently releasing its flagship devices in two different variants – Exynos and Snapdragon since the S7 era. The trend continued with the Galaxy S8/Note 8 series and is still persistent with the latest Galaxy devices. I already have a tutorial covered on this website to root Galaxy S8/S8+ with Exynos SoC and it is based on the standard rooting method that involves installing TWRP and then flashing SuperSU/Magisk via it.

But things tend to get a bit complicated when it comes to Snapdragon-equipped Samsung devices and rooting. That’s because, unlike the Exynos variants, the bootloaders on the Snapdragon variants sold in the US are not unlock-able. And hence, the generic method of flashing TWRP via ODIN and then rooting through Magisk would fail rigorously.

Rooting Galaxy S8 Snapdragon using Extreme Syndicate Method

This guide has been updated multiple times in the past with new root methods that were discovered for the Galaxy S8 snapdragon. The last one that worked, and on which this guide was based on till now, was the ‘EDL method’. But that was limited to phones with V5 and V6 bootloader version. With the most recent software updates from Samsung, the bootloader version was bumped up to V7 and that process didn’t work anymore.

But thanks to the Extreme Syndicate team, you can now root your Galaxy S8 Snapdragon variant. This new method and the involved exploit was found by team member and XDA Recognized Developer elliwigy for the Galaxy S9, S9+, and Note 9 equipped with the Snapdragon SoC initially. Another team member and XDA RC jrkruse, who is also responsible for the previous root solutions for this device, ported the new method for the Galaxy S8.

I have already covered a guide to root Galaxy Note 8 Snapdragon using this same method. The only difference between both the guides is the files used during the process.

The Extreme Syndicate root method basically uses an exploit found in the Android Nougat combination firmware (A low-level test OS) to root the phone. From there on, you can either install the pre-rooted Nougat ROM or the Android Pie ROM with Safestrap recovery. Now before you go ahead and follow the instructions, take a look at some of the important information about this new root process.

  • This method supports any Snapdragon Galaxy S8 sold in the US with V7 bootloader version.
  • You can use this method despite the Android version installed on your phone. However, in order to gain root permissions, you will need to install a pre-rooted Nougat ROM. The supplied Nougat ROM is pre-rooted with SuperSU and has Flashfire and Safestrap recovery pre-installed.
  • If you’d strictly want to stick with Android Pie, you can opt for the Android Pie ROM and use the Safestrap recovery to apply modifications to the software.

With that information at hand, head over to the instructions to root Galaxy S8 Snapdragon.

How to Root Snapdragon Galaxy S8

Supported Devices

The following Galaxy S8 model numbers are supported. If your device has a model number other than the ones mentioned below, then this method will not work on it.

  • SM-G950U
  • SM-G950U1

This process will work regardless if your Galaxy S8 is running Android 9 Pie, Android 8.0 Oreo or Android 7.1.1 Nougat. What’s important is that your Bootloader version/revision must be V7

To find out your phone’s bootloader version, go to Settings → About phone → Software information and check the information under the ‘Baseband version‘ section. For example, if it says “G950USQS7DTB3”. The “S7” here denotes the bootloader version, which is V7.

A word of caution & disclaimer

Make sure that you go through the instructions beforehand and understand what they exactly tell you to do. Do not deviate from them at any point or disconnect/power off your phone during the process until you’re asked to do so.

Rooting is a risky process and, or any of its members shall not be held responsible for any damage caused to your device during or after following the process.


  • Your device’s internal storage and all data will be wiped (Possibly more than a few times) during this process. So make sure that you take a complete backup of all your data stored on the phone. We suggest you follow our guide on how to backup Android phones.
  • Charge your Galaxy S8’s battery to a sufficient battery level. The whole process is a bit long and you wouldn’t want your device to suddenly switch off during it.
  • Install the latest Samsung Mobile USB drivers on your PC.
  • Lastly, download Modded Odin3 3.13.1 by Raymonf from here and extract it on the PC. Do not use the normal version of the Odin tool for this method!

How to Root Galaxy S8 Snapdragon?

For your convenience and better understanding, I have split the instructions into six (6) major steps. Make sure that you follow each and every step in the mentioned order and do not deviate from them at any point.

Step 1: Perform Factory Reset and Enter Download Mode on Galaxy S8

The first step in order to root is to perform a factory reset via the stock recovery and then boot your Snapdragon Galaxy S8 into Download Mode. To do so, power off your phone first. Then hold the Volume Up, Bixby, and Power buttons simultaneously to boot your phone into the stock recovery mode.

Perform Factory Reset on Snapdragon Galaxy S8 using Stock Recovery

In recovery mode, use the Volume buttons to select the ‘Wipe data/factory reset’ and press the power button to confirm the selection. When prompted, select ‘Factory data reset’ to confirm and perform a factory reset. Once done, select the ‘Reboot to Bootloader’ option in the stock recovery to enter Download Mode on your Galaxy S8.

Boot Snapdragon Galaxy S8 into Download Mode

With your phone in Download Mode, it is now ready to be flashed with the combination firmware. So, head over to step #2.

Step 2: Flash Combination Firmware using Odin Flash Tool

Download the combination firmware package (COMBINATION_FA70_G950USQU7ASK1.tar.7z) for your Galaxy S8 from the ‘Downloads’ section above. Once downloaded, extract the file (using 7Zip, or any other archive utility) to a suitable location on your PC. You should now have the combination firmware file for your phone in .tar.md5 format. This is the file that needs to be flashed.

So now, connect your phone to the PC while it’s in Download Mode using a USB cable. Then launch the modded Odin tool by double-clicking the ‘Modded Odin v3.13.1 Raymonf.exe‘ file. The Odin tool GUI should now be shown on your PC’s screen and it should display the COM port to which your phone is connected. Click on the ‘AP‘ button and select the combination firmware file (i.e. COMBINATION_FA70_G950USQU7ASK1.tar.md5) that you extracted earlier.

Flash Combination Firmware on Snapdragon Galaxy S8 using Odin



Now, you’re ready to flash your phone. Just make sure that the ‘F.Reset Time‘ and ‘Auto Reboot‘ options are checked in the Odin tool. Finally, hit the ‘Start‘ button in Odin to flash the combination firmware on your Snapdragon Galaxy S8.

Once the flashing process finishes, you should see a ‘PASS!‘ message in the Odin tool and your phone will reboot automatically into the combination OS. Since this is a low-level testing firmware used by Samsung internally, the UI will differ. It should look similar to the one shown in the image below.

Combination Firmware (Test OS) on Samsung Galaxy S8/S8 Plus Snapdragon

Step 3: Run ‘APPS_INSTALLER.bat’ and Reboot the Phone

Now, in this step, you have to run a batch file on your PC which will sideload some apps that are required to go ahead with the rooting procedure.

So, with your Galaxy S8 now in the combination OS, connect it to the PC via a USB cable. Then download the ‘S8_ROOT.7z’ file from the ‘Downloads’ section and extract the file on your PC. The extract files should contain the ADB binaries, a bunch of APK files, and two Windows batch files namely ‘APPS_INSTALLER.bat’ and ‘ROOT_INSTALLER.bat’.

Run 'APPS_INSTALLER.bat' file on your Windows PC

Simply double-click the ‘APPS_INSTALLER.bat’ file to run it. It will sideload/install the required APK files on your Galaxy S8. Once finished, reboot your phone.

Step 4: Grant Read, Write, and Execute Permissions for ‘Persist’ Partition

When your phone boots, it should prompt you to select the default launcher application. Choose ‘Pixel Launcher’ as it would make easier for you to find the installed apps.

Now go to the app drawer, launch the ‘Factory IME‘ application, and enter *#9900# in the dialer. This should open the ‘SysDump‘ screen that will show a lot of different debugging tests. Scroll down, select ‘AUDIOCORE DEBUG‘, then ‘TEST HELPER‘, and finally ‘Utils‘.

Launch Factory IME App on Snapdragon Galaxy S8

You should now see the ‘AUDIOCOREDEBUG‘ screen with a couple of options. Tap on the box that says ‘ADB Commands‘, type in ‘chmod -R 0777 /persist‘ and press the ‘SEND‘ button. The command will basically grant read/write/execute permissions to the ‘Persist’ partition of your Galaxy S8.

Enter ADB Command in AudioCoreDebug

Step 5: Run ‘ROOT_INSTALLER.bat’ to root Galaxy S8 Snapdragon

Now, in order to root your Snapdragon Galaxy S8, you have to run the ‘ROOT_INSTALLER.bat’ file on your PC. To do this, simply connect your phone to the PC via a USB cable and double-click on the ‘ROOT_INSTALLER.bat’ file that you previously extracted during step #3.

The batch file will copy all the required root binaries and reboot your phone. When your Galaxy S8 reboots, it should be rooted via SuperSU and you can confirm this by launching the ‘FlashFire’ application. At this point, you will also have the SafeStrap Recovery installed on your phone.

Note: If the script fails to work and shows an error, please try this trick posted by one of our readers (Thanks ApexMcCaprino!)

Step 6: Install the ROM

The process isn’t over yet. As you may notice, the phone is still running the combination OS. From here on, you have two choices – (1) Install Pre-Rooted Nougat ROM or (2) Install Android Pie Safestrap ROM.

Step 6.1: Install Pre-rooted Nougat ROM

  1. Download the pre-rooted Nougat ROM system image and Nougat-compatible Safestrap recovery files from the ‘Downloads’ section of this post.
  2. Extract the “system.img” file from the downloaded “Rooted_G950USQS2BRB1.rar” file using an archive utility (like 7Zip, WinRAR, etc).
  3. Transfer the extracted “system.img” and “” files to your phone’s storage.
  4. Now reboot your phone and press the ‘Recovery’ button when you see the Safestrap splash screen.
  5. In Safestrap, tap on the “Install” button and then on “Install Image”.Install Pre-rooted Nougat System Image on Snapdragon Galaxy S8
  6. Navigate to your phone’s internal storage and select the “system.img” file. When prompted to select the partition, select “System Image”.
  7. Swipe the button on the bottom to flash the pre-rooted Nougat System Image on your Snapdragon Galaxy S8.
  8. Now go back to the recovery’s main menu and press the “Install” button again.
  9. Select the “” file and flash it.
  10. Once done, go to the “Reboot” menu in Safestrap and tap on “DOWNLOAD”. Your phone should now reboot and enter the Download Mode.Enter Download Mode on Snapdragon Galaxy S8 using Safestrap Recovery
  11. Connect your phone to the PC while it is in Download Mode.
  12. Download the V7 bootloader file (BL_G950_NOUGAT_V7.tar.7z) on the PC and extract it.
  13. Launch the modded Odin tool by Raymonf and select the “BL_G950_NOUGAT_V7.tar.md5” file in the “BL” slot.
    Install Nougat BL with Fingerprint and Face Unlock Fix on Snapdragon Galaxy S8
  14. Finally, click on the “Start” button to flash the file.

Once the flashing process finishes, your Galaxy S8 will reboot into the pre-root Nougat OS with Safestrap recovery installed. You can now download and install root applications of your choice or mods like ViPER4Android to enhance the audio on your phone.

Further, according to the developer, it is important to flash the Nougat-compatible Safestrap Recovery ( via the Safestrap itself to fix constant booting into Safestrap.

Step 6.2: Install Android Pie Safestrap ROM

Download the Android Pie Safestrap ROM package from the ‘Downloads’ section. Extract the downloaded ‘G950USQS7DTA6_SAFESTRAP.rar’ to a new folder. The extract files should contain the Android Pie system image, BL, and CSC files.
Snapdragon Galaxy S8 Android Pie Safestrap ROM Files

Transfer the ‘DTA5_SYSTEM.img’ file to your Galaxy S8’s internal storage. Once done, reboot your phone into Safestrap recovery mode. To do this, power off the phone and turn it on. When you see the Safestrap splash screen, simply press ‘Recovery’.

In Safestrap recovery, go to ‘Install’ and press the ‘Install Image’ button on the bottom. Navigate to your phone’s internal storage and select the ‘DTA5_SYSTEM.img’ file that you transferred earlier. When prompted to select the partition, select ‘System Image’ and swipe the button to flash the file and install the Android Pie ROM on your Snapdragon Galaxy S8.
Install Android Pie System Image on Snapdragon Galaxy S8 using Safestrap Recovery

Now, the other files that you need to flash are the Android Pie BL and CSC files through Odin. To do this, boot your Galaxy S8 into Download Mode by going to the ‘Reboot’ menu in Safestrap and tap on ‘Download’. Next, connect the phone to the PC while it’s in Download Mode.

Launch the modded Odin tool by double-clicking the ‘Modded Odin v3.13.1 Raymonf.exe’ file. The COM port for your connected phone should appear on the top-left of the Odin screen.

Now, click on the ‘BL’ button and select the ‘BL_G950USQU7DTA6.tar.md5’ file to load it. Next, click on the ‘CSC’ button and select the ‘HOME_CSC_OYN_G950U_CACHE.tar.md5’ file. Once both the files have been loaded, click on ‘Start’ to begin the flashing process.

Install Android Pie BL and CSC Files on Snapdragon Galaxy S8 using Odin

After the flashing process finishes, you should see the ‘PASS!’ message in Odin, and the phone should reboot automatically. You now have Android Pie ROM installed on your phone, along with pre-loaded SafeStrap recovery.

From here on, you can use Safestrap to flash compatible mods on your rooted Snapdragon S8. You can look up for such mods on the XDA forums or consult the developer by visiting the original XDA thread. The link for the same could be found at the bottom of this post.

So, this was our guide on how to root Galaxy S8 Snapdragon running V7 bootloader, using the new Extreme Syndicate root method. If you come across any roadblocks during the process, drop a comment below, and I will be more than happy to help you out.

I couldn’t end this post without thanking XDA RC jrkruse, the complete Extreme Syndicate team, and everyone who contributed towards this successful root solution.

  1. I’m trying to recover files on S8 internal memory which all recovery programs say I need to root my phone.

    I have tried several methods and found that S8 is impossible to root.

    I ran into this thread but my baseband version # is different then the one listed.

    Samsung Android 9 S8 SM-G950U
    Baseband Version – G950USQU8DUA2

    I have search and found nothing specific to my phone. Will this root process work with mine? Also, if I backup my data will I still be able to recover file from internal memory if I factory reset?

    1. Kevin, while this method will work on your Galaxy S8, there are a two things that I would like to point out:

      1) Root access does not guarantee full recovery of lost/deleted data. I have gone through the same situation in the past, even tried some paid solutions, but all I could recover at the end were some photographs. Overall, I was only about to recover merely 5-10% of the data I lost. If those files are extremely important, you could try and this brings us to the second thing.
      2) This method of gaining root access is completely different than the one that’s followed and used for Galaxy S8 models that support bootloader unlocking. This method uses an exploit found in an older firmware to attain root. It is also more complicated and susceptible to more errors than the traditional method of unlocking the bootloader & then rooting.

      I also haven’t had the time to update this guide with more up-to-date files and instructions. From the software version info you have shared, your Galaxy S8 has a V8 bootloader. I suggest you take a look at the original XDA thread for the latest files and instructions provided directly by the developer.

    1. For the S8+, refer to this tutorial.

      If your phone has v8 bootloader revision, I suggest you visit the source XDA thread for the latest files.

  2. This process goes perfectly until after step 6.2 once 6.2 is completed the phone reboots no root (expected this is not the pre-rooted ROM) but it also does not contain the custom recovery of Safestrap but instead, stock recovery opens when prompted. Got any suggestions?

    1. Hi Jack. I believe I failed to mention and explain that.

      What you need to do is:
      1) Boot your phone into Download Mode and connect it to the PC
      2) Flash the “BL_ENTER_SAFESTRAP_G950UDTA6_V7.tar.md5” file through the ‘BL’ slot of Odin.
      3) Your phone should enter Safestrap.
      4) To exit Safestrap, go to the “Reboot” menu and press “Download”.

    2. Using this method I’ve been able to access Safestrap but after say flashing SuperSU then I tried flashing (Using Odin) BL_LEAVE_SAFESTRAP and just the base bootloader given for flashing after (SYSTEM).img but I can’t get it to boot I don’t really know what happened. But I can get it into download mode and recovery just not the system.

  3. Supersu hide doesn’t work I flashed the updated zip with flash fire and ended up getting and error just like Jordan below.
    System software not authorized by at&t has been found on your phone. Please turn off your phone and go to the nearest at&t store

    1. There seems to be some confusion. After I ended up with the ” this phone has been flashed with unauthorized software …….”


      Dhananjay Thank you for your helpfullness. Thank you creaters. Just stick with what they have and be glad that this model can even be rooted to begin with.

    2. Hi Cody. Yes, SuperSU is the only way to gain root on the S8 series and Note 8, because of an exploit found by an ingenious XDA developer.

      You’re much welcome! All the credits go to developers elliwigy, jrkruse, and everybody on the entire Extreme Syndicate team. I merely tried to expand their original instructions, that’s all.

    1. Hi Brian. I don’t think that would be possible with SuperSU. Back when SuperSU was in active development, developer Chainfire released suhide as an experimental project. You can find more info about it here on the XDA thread.

      However, it’s surely not as efficient in hiding root like Magisk does. Plus, I have no clue if it would work on this rooted setup or not. But you can try if you’re willing.

    2. I’ve already tried this method but I can’t seem to get the part where you switch super su to sbin

    3. Hi Brian. Could you please share the exact step where you’re stuck? Also, please describe the exact issue/error that you’re facing.

    4. Btw not me up above…but when I try and use this method when installing latest version of supersu zip when It gets to the boot image it says extracting ramdisk then failure, aborting. And if I just try to flsh the su hide zip it says to make sure to have the latest supersu installed, so I’m not quite sure if this method will work or if I’m doing it wrong.

    5. You mean you’re trying to flash SuperSU ZIP file via Safestrap or Flashfire?

    1. Yes. First of all, download the latest stock firmware for your phone using this tool.

      Once you have downloaded it, follow the instructions on this page to flash it.

      After this, you will have your phone restored to the stock firmware and you can retry the rooting instructions again.

  4. I need help I rooted my phone using this method and I installed magisk and my phone got stuck in a boot loop saying system software not authorized by at&t has been found on your phone and go to the nearest at&t store for help??

    1. I also tried downloading official 9.0 backups and flashing them they didn’t work so any ideas are welcome I just need help?

    2. Hi Jordan. You cannot flash Magisk or any other root binary using this method. You can either stick with the Nougat setup which is pre-rooted with SuperSU or move to Android Pie with Safestrap ROM (which is without root).

    3. Is there anyway for me to get the phone back to normal I’m able to go in to normal phone recovery and download mode but idk what to flash

  5. I did everything exactly how it instructed me to do it and everything worked perfect but after doing everything my device does not have root

    1. Hi Jordan. Towards the end, did you go with the Pre-rooted Nougat or Android Pie Safestrap ROM?

  6. I’ve been trying to root my S8 G950U. But it keeps staying at “Setup Connection” in Odin. Already reinstalled drivers, changed Odin version, opened as administrator, and somethings more.

    1. I know that this and more modes don’t work on my model. So if someone has anyway which with I can root my phone, I’ll aprecciate it.

    2. Hi Ricardo. Did you try using the Modded Odin version by Raymonf? You can try the one provided with the “S8_ROOT.7z” package or download it individually from here.

  7. I couldn’t even get past first step. secure check fail pit file….using Raymond odin and on pie with v7 bootloader….

    1. Hello John. Is it the Galaxy S8 or the S8+ you are using? Also, are you trying this directly on a Windows PC?

    2. NEVERMIND. ive got the note 8 NOT galaxy s8…no wonder it wouldn’t work…

    1. Hi Bob, please retry again after a few minutes. It’s live on my end. AndroidFileHost may not be able to find a download mirror when you tried.

  8. ok i retraced my steps and ran it thru a couple more times. the problem is where i do the chmod -R step. apparently when i press send nothing happens. it doesnt add the write permission to persist so the rest of the process falls apart in the end i guess cuz theres nothing being saved. how can i solve this? ive gone through it a couple times through and made sure i took care to type the command exactly as is. im glad i located the problem tho cuz i thought i was dreaming. ty for any help, tim

    1. Hey,

      I’ve been in the same situation here.
      Here’s the trick I used :

      – Execute the first bat, then chmod even if it does nothing.
      – Execute the second bat.
      You should see the error :

      “chmod – […] no such fil or directory”
      It’s okay if i’ts the only one you get but the files got pushed on the phone.

      Reboot to safestrap and then open adb from here ( on your computer, you should be abl to adb shell while you are on safestrap )
      adb shell
      > su
      # chmod -R 777 /persist

      and that should do the trick.

      you can then proceed to flash your custom rom

      hope this helps !

    2. Thanks ApexMcCaprino! I have added a link to your comment right under step #5. So if anyone faces the same problem, they could use your observation and expertise. Thanks again.

    3. i install nugot rom how can i get it to stop booting up with the safe strap

    4. Hi. Every time you boot your phone, you have to keep the VOLUME UP + BIXBY + POWER keys pressed together until the Samsung splash screen shows up. This will boot your phone into the rooted Nougat OS.

  9. also i forgot to mention in my previous post that the only thing different about the process is that my phone never had that black screen with the boot options to begin with. ive never been able to get do it. following the 3 button holding method of accessing boot, it always just goes right to the blue/green download screen with no other options but to restart. aside from that odin worked fine, everything worked fine. not sure if that helps. ty again, tim

  10. Hello. i have an s8 snapdragon sm-g95ou1 US rev 7 firmware

    this article was very well done. ty for that. a lot of them are not. i downloaded every file listed before hand. i then followed every step to the T. i ran into 0 problems along the way. everything went exactly how it flowed in the directions and pictures. i chose to install pie, so i didnt mess with the nougat instructions. went through the pie installation procedure to the T. no problems. got to the end. finished. rebooted my phone and the stock os loaded like it was never gone. the only thing that remains of the entire process is the twrp app is still in the menu (without root this time) its almost as if 99 percent of everything happened, then it just poof. vanished at the end like it never took place. im kinda out of ideas atm. could you offer me some direction please. ty, tim

    1. Hi Tim, thank you so much for confirming that it worked and the guide was helpful. I just merely tried to explain all the steps in detail. The credits for the steps, the files, and the method goes to the Extreme Syndicate team and XDA Developer jrkruse.

      As for the chmod command, it will show nothing when you send it, but it works. When you did step #5, did the ‘ROOT_INSTALLER.bat’ file install everything correctly?

  11. Well, i took the same steps once i install the pre-rooted version of nougat I’m having the same issue with settings keep crashing. But i managed to install the google firmware which is debloated with a nice boot animation and less bloated. Not sure when my settings keep crashing once i install pre-rooted nougat

    1. That’s odd. The system crash doesn’t occur after installing the Google ROM?

      Also, did you try skipping through the setup and then turning ON WiFi via the settings?

      I am sorry that I haven’t been able to be of much help with the crash.

  12. Good morning this post was very helpful, I was able to root me s8+ g955u.
    Once the phone loads up I was unable to connect to my wifi, each time I press the wifi the phone freezes then settings crash no 4g service either not sure what went wrong at the end but some advice would be greatly appreciated.

    1. Hi Paul. Did you use the provided files on an S8+? This post is only for the S8 (G950U/U1). For the S8+, please refer to this post. The steps for the S8+ are much shorter and easier.

    2. Sorry yes, i did use the post for the S8+ after I submitted the post I realized I was on the s8 instead. But once the process completes successfully and loads up without an issue I notice I cannot connect to my wifi in settings it keeps crashing or no data service available.

    3. Hi again Paul. Did you just root or installed the Android Pie Safestrap ROM further?

    4. No im using the nougat pre-rooted method
      Im currently on Pie when i try safestrap with pie safestrap don’t seem to work, but the issue I’m having is with the pre-rooted nougat method

    5. Currently, in using a stock version of Pie TMB I followed the instruction on how to pre-root s8+ with the nougat firmware. So I followed the guide for the s8+ and it was successful. Once the pre-rooted nougat loads up to the point where I need to connect to my wifi in settings the phone would freeze then settings would crash and prompt to reload. So I’m unable to connect to wifi or my mobile data using the pre-rooted nougat that was posted for s8+ model.

    6. Hi again, Paul. Could you tell me the software build number of the Android Pie firmware that’s currently installed on your S8+? You can find this info by going to ‘Settings’ > ‘About phone’ > ‘Software information’.

    7. Okay. So, in brief, you did the following:

      1) Performed a factory reset
      2) Flashed the BL V7 Safestrap file via Odin
      3) Force-rebooted the phone into Download Mode
      4) Flashed the AP Rescue System Image (tar.md5) via Odin which resulted in the ‘FAIL!’ message
      5) And finally, re-flashed the BL V7 Safestrap file

      Did you do anything differently or exactly the same? I would suggest reperforming the steps from the start and see if it makes a difference. I performed the same thing on my friend’s S8+ (SM-G955U1) and fortunately didn’t face any issue with WiFi.

      Let me know how it goes.

  13. Followed these instructions and it worked great! Thanks! I’m using an app that appears to only run on android 7.1 and higher, what’s the best way to upgrade without losing root?

    1. Hi John, I am glad it worked. The credits for this go to all the members of the ES team who made it happen.

      There’s no possible way to upgrade other than using the Android Pie safestrap ROM. But then, you will lose root. The root was made possible through an exploit found in the specific Nougat firmware, I am afraid, you will have to stick to it if you really want root.

      May I know which app are you talking about?

  14. hola, quiero rootear mi s8+ g955u, pero al parecer la guia ha sido cambiada y ahora solo soporta g950U puedo saber como rootear mi g955u?

    1. Hi J.sama. Since the Galaxy S8+ follows a much easier and a different method than the one followed for the regular S8, I created a separate guide for it. You can check it out by clicking here.

      If you want to just root and stay on Nougat ROM, follow just till step #2 in the guide I linked. If you plan on installing Android Pie ROM + Safestrap recovery (without root), then please let me know before you proceed with the guide.

  15. Hi I am stuck with trying to get the S8_Root.7z file I have tried each one and get it either been deleted for a virus or it cant be opened. I have turned my virus protection off tried different apps to extract it even tried to get file from XDA Forum and still nothing, can you please tell me what exactly am I doing wrong?
    Thank you in advance

    1. Hi Dom, do you have third-party antivirus software installed? If so, then you have to disable real-time virus protection in both the antivirus software and Windows Security.

      I have done the same and it worked for me.

  16. hi, i did everything to the letter until step 5 after that my phone starts at the samsung logo and restarts several times.

    1. Hi J.sama. Which software build number did you phone had before you tried this rooting procedure?

    2. Hello,my phone got no service and shows mipi device fail my verison is G955USQS7DTB3 and i was told to get to secret menu with code *#27663368378# and restore rv.
      How do i do that?please help

  17. Hello
    I have Samsug galaxy s8plus version version
     USA has been unlocked Because I’m in Vietnam
    I wonder if I can unlock my bootloader and root my device with this method.
    And I have another question is if I can unlock the bootloader and install twrp from this method, can I upload the rom cook to my phone. Looking forward to hearing from you. thank you

    1. One more thing is my galaxy s8 pluss Galaxy Phone is model G955U1 and is using Android 9.0 operating system

    2. This is all I got when pressing * # 1234 # :

    3. Hi Soan. Unlocking the bootloader isn’t possible at all on the U/U1 variants. The method simply uses a combination firmware for gaining root permissions on Nougat OR installing Safestrap recovery on Android Pie.

      The developer recently released a new method that works on V7 bootloaders, such as yours. I will be updating this post once I have updated the Note 8 guide for the same.

      If you have any more questions feel free to let me know.

    4. Hi Dhananjay. My baseband version is G955USQS7DTB3. It means my bootloader is V7?
      and if its v7, then could you please tell me how to root v7 G955U T Mobile S8+? As you said in this comment ” The developer recently released a new method that works on V7 bootloaders, such as yours. I will be updating this post once I have updated the Note 8 guide for the same.”
      As i am in Australia. My phone is not picking up the carrier and i want to open it sim features. Thanks in advance. Looking forward to your reply. Or if there is any contact details like email or something you can share so we can sort it out this problem together if you dont mind. Thanks again. Cheers

    5. Hi Haris. Yes, the developer has released a new method that works even on V7 bootloaders. I am in midst of updating the Note 8 guide, after which I will do this one.

      Instead of rooting, have you thought of unlocking your phone’s carrier so that it can be used on other networks? Maybe that will be much easier. Check this T-Mobile page here.

  18. hello can you help me? im stuck in edl reboot. my phone not response can you explain how to enter edl mode step by step

    1. Hi Bayu, is it showing a black screen with or without the notification LED glowing?

    2. Hi. No, Magisk cannot be installed using this method. You will have to use the SuperSU system-root that’s supplied.

    Can I rooted my phone

    1. Hi Ahmed. Yes, you can use this method. By the way, may I know why do you want to root the phone in the first place? Just curious to know.

    2. my phone was formated so I need to recover my files

      what is Bootloader v5 or v6

  20. Hello there !! Awesome work brother ! .. but i still have a problem .. in my country my mobile’s imei number is blocked to call or use my sim network … Is there any method available for unlocking it .. and can you please guide me .. im really worried about it its like wasting my 600$ … Thanks ❤️

    1. Like can i change my imei number when i put my mobile to test os screen? Without gaining root ?

    2. Hi Saniarao. Yes, there are methods available to unlock the phone to be used with any carrier. But as far as I know, these methods are paid.

      May I know to which carrier the phone was actually locked to?

    3. Actually its not Carrier’s fault .. its just they block the specific Imei number to make any call or use the data….. I’ve heard people here are changing IMEI number and then they could make calls and use the cellular network. .. but I can’t root my s8+ and can’t downgrade to nougat too coz its just so outdated. .. and missing many features .. thats why i just wanna change my imei number and finding any methods for it … Hope you understand my situation ..

    4. Yes, I understand. However, changing the IMEI isn’t legal in most countries and goes out of the context of this article too. Sorry that I couldn’t help you with it.

  21. Thanks for your explanation. But I do have a question. I have s8 Plus with carrier t mobile. I want to change it to non carrier brand! I get combination file with android version 7 bootloader v 7. And my version is android 9. I successfully enter in the factory binary. But the problem happens when I try to install only home csc file. It says verification failed. Is it because my combination firmware (android 7) is not matching with home csc file which is android 9? How can I fix it? Thanks

    1. Hi Ermias. That’s correct. That’s the file mismatch error you’re getting.

      Is your phone the G955U model or the G955U1?

  22. Good I have a s8plus g955u with rom g955u1 Android 9 binary 5. I would like to root it as I can do it without dying in the attempt is v5 but the version I published is v6 as I get the print for v5. Thank you

    1. Hi Antonio. Please open the dialer on your phone and enter *#1234#. Let me know the software information it shows on the screen.

  23. Buenas tengo un s8plus g955u con rom g955u1 Android 9 binario 5. me gustaría rootearlo como puedo hacerlo sin que muera en el intento es v5 pero la versión que publicase es v6 como consigo la huella para v5. Gracias

    1. Hi. As per the info you have provided, it’s BL version 7, which is currently not root-able. I am afraid, but you’ll have to wait until the original developer of this root solution (jrkruse) provides updated files for BL v7.

  24. I followed the procedure exactly and got through step 6 where I went to download mode to flash the BL_G95*_FINGERPRINT_FIX_V6.tar.md5 file. Odin read as passed and phone went to boot up. The SAFESTRAP DISABLED with a picture of a robot underneath popped up and stated that the system will now boot in 10 seconds. After which the phone rebooted and it is stuck in the pulsing SAMSUNG logo with a tiny blue light at the top left corner of my phone… but it won’t leave that screen. It’s like it is stuck on that screen. What did I do wrong?

    1. Hi Jason. First of all, did you use and flash the correct files according to the model number (G965U/G960U) and bootloader version that was installed on your phone?

    2. First of all, thank you so much to the OP and the developer of this exploit. Your efforts are very much appreciated, and I think the work you all do is often overlooked. I am not a developer, but I do appreciate the immense level of work that it takes to accomplish a feat such as this. I have an AT&T SM-G950U. Just in case Jason doesn’t reply back, I had the same thing happen. I flashed the Nougat system.img and Safestrap recovery for Nougat, rebooted to download mode, flashed the fingerprint fix and the device rebooted to the OS and I let it sit there for about 6 hours at the Samsung logo screen. Force rebooted several times, went into recovery and wiped cache/Dalvik, and no change. Finally, without flashing back to stock, I started over from step 1, and after finally rebooting to the Nougat OS after step 6, my device booted in about 2 minutes. For anyone running into what Jason and I did, just start over from step 1 and see if that takes care of it. I did not do anything different the second time around, so I cannot say specifically went wrong. Likely either user error or something specific to our devices and the pre-resident software. Again, thank you Madhav Rao and Dhananjay for your efforts!

    1. Hi again, Ernest. Since I personally do not own the device (only had the Note 8 snapdragon previously), I could not confirm. I don’t think there any reason for it to not work.

  25. Oh one more thing. Making backups and restoring backups. How wold one do that without loosing safestarp ?

    1. Hi Ernest. Thank you for the kind words! I am glad the tutorial proved useful to you.

      Below, I have tried and answer all your questions:
      1) No. It’s the latest one available for the S8/S8+. If you’re experienced, you can these instructions provided by jrkruse on creating your own modded system.img for a specific firmware version.
      2) Yes, the slots are for multi-booting ROMs. However, it doesn’t work in this case.
      3) You can take NANDroid backups directly via Safestrap’s “Backup” menu.

    2. Thank you for the info your reply ( You can take NANDroid backups directly via Safestrap’s “Backup” menu.)

      I understand the nandroid backup up. I have a S5 . I am constantly backing it up . because I like to explore beyond what is possible. And because of this I am constantly doing backups of the system when it runs perfectly . I store the backups on a hard drive on the network . The backup could be any android OS . With the S5 its a simple as wiping everything and restoring the the boot ,system and data partitions. And I am right back where I want to be in minutes.

      I have tried that with the S8+ 6955U and when I wipe everything and then restore the backup I loose the safestrap recovery . What am I doing wrong ?

      Thank you for help I see you answer lots of questions with this . The world needs more people like you

    3. Hi, again Ernest. With the Snapdragon variant + Safestrap, NANDroid backups may behave differently according to the partitions that you back up and restore.

      Could you please share a screenshot of the “Backup” menu in TWRP, where it asks you to select the partitions? Also, please let me know which partitions did you exactly chose to back up.

      And thank you too, Ernest. I am so happy that my help is being recognized. 🙂

  26. Great job with this. I have a S8+ 6955U Verizon with V 6 boot loader. Followed the directions with no issues fairly quick and easy. I chose to use the Pre-Rooted Nougat system. Are the any other pre rooted systems or non rooted than can be rooted to try ? The slots in the safe strap recovery, Are they for installing different O.S. in them? Does it work ? Thanks for the great work jrkruse and the other developers that were involved. This write up was much easier to follow than the others I have read

  27. I’m planning to try this with the SM-G9500, which is a phone from Hong Kong….

    If it works, I’ll post.

    Meanwhile, has anyone already failed or succeeded with this model? It’s a snapdragon.

    1. Hi Jim. Please don’t try the method on the SM-G9500. Although it’s a Snapdragon variant, but it does support bootloader unlocking.

      TWRP for the device is already available here. But I am not entirely sure if it’s possible to flash Magisk to gain root.

    2. I’m also on 9500, the bootloader is V3. I’m going to attempt this today and tomorrow. Any help would be greatly appreciated, especially info on how to work with the V3 bootloader

    3. Hi Jim. Did you intentionally stick with V3 bootloader? I think the latest Pie firmware for your model has V5 bootloader.

      I would be very happy to help, please let me know if you have any more questions.

    1. Is possibble to root if i downgrade from 9 to 8 ?
      or you know firmware pie downgrade supporting root samfail v4/v5.

      lastest firmware : G955U1UES7DSK4
      before : G955U1UES6DSJ1

    2. Hi Herguri. It is possible to downgrade to a firmware, only if the bootloader version of the current and desired firmware matches.

      For your provided info, the latest firmware has V7 bootloader and the previous firmware had V6 bootloader. This means that the downgrade is not possible.

      I am also updating this post with the current root method for V5/V6 bootloader. But it will not work on V7 bootloader that you have (not yet, at least).

    3. Hi Dhananjay,

      Any rough idea when or if the V7 bootloader will be supported for root? I was very eager to root my old S8+, but it looks like I’ll have to put that on hold for now :/ Thanks in advance!

    4. Hi Pagani. There’s no confirmation by the developer on V7 yet. But I am sure it will be supported soon.

  28. Hi,
    My baseband version is: G955USQS7DSK2

    So I assume that I am on a BL v7, correct?
    Does this method work for BL v7?

    1. Hi Otari. No, the method won’t work on V7 bootloaders. There’s a new method, but that is also limited to V5 and V6 bootloaders.

    1. Hi Herguri. That’s because your phone’s bootloader version (V6) doesn’t support this method. A method to root is already available for V5 and V6 BL, but I am currently working on the guide. The new guide that I am working on, will replace this current one very soon.

      I request you to wait for a few days.

    2. Hi Frnk. Sorry to keep you waiting. I am trying my best to complete it. Have a lot of impending posts to do.

    3. Hi Frnk. The guide has been updated to reflect the new instructions along with the corresponding files.

    4. Hi Mitch. The guide has been updated and should work for V6 bootloader now.

  29. Yeah. I went through the process twice. It’s stuck on the wifi setup. It says “turning on wifi”

    1. Hi tj15401. Which bootloader was your phone using before you started with the instructions?

  30. I used the Note 8 method and everything seems well except that wifi will not turn on…any suggestions?

    1. That’s great, TJ15401! Did you perform a factory reset after performing the whole procedure?

    1. Hi. I am afraid, no. This post needs to be updated with the latest files and instructions for V5 and V6 Bootloaders. I will be starting it tomorrow and should be done in 3-4 days.

  31. Hi brother.. I found a bug again, when I connect to WiFi, the password is not automatically saved in the system.. so I have to recharge the password continuously.. do you know how to fix it? any help I really appreciate.. thank you

    1. Hi Vinz. I am revising this guide from scratch, which will work with V5 and v6 bootloader versions. I might possibly have the least amount of bugs, considering that it uses the latest pre-Nougat ROM.

    2. Hi bro..
      Ok brother, when will the new revision be released? Do I have to repeat the flashing again later? is there a newest ROM link? Which ROM should I choose? I can’t wait for it hahahaha

    3. Hi Vinz. If you’re so eager, then I can direct you to files and instructions. Right now, I am a bit occupied with another article regarding the Galaxy S10 that is on the verge of completion.

      The required files could be downloaded from here, and you will need to follow the same instructions as for the Snapdragon Note 8, which are provided here.

      The instructions are exactly the same as for the Note 8, you just have to use the S8+ specific files.

      If you’re not confident about it, I suggest you to wait. But if you have had previous experience with rooting/flashing, then you MAY go ahead.

  32. Hi bro.. this method is successfully happy , thankyouu brother.. but after i’m root my galaxy s8 plus (SM-G955U) , i charge my battrery and why max battery is 80% cannot 100% ? I dont know why , can you fix it? Help me please 🙁 thanks before

    1. Hi Vinz. Don’t worry, it is actually charged to 100%, it just shows 80%. It’s a known drawback of using SamFAIL method for rooting.

    2. thanks brother, I want to ask again about wifi direct, is there a way to use it? because i tried to send photos using wifi direct but can’t .. so what should i do? sorry if I ask many questions, sorry if my questions bother you my friend .. thank you in advance .. your help is very meaningful to me

    3. Hi Vinz. Don’t worry about the questions, that’s what this comment section is here for. I am truly happy to help any way I can.

      I haven’t seen/read anyone reporting about issues with WiFi Direct. What’s the exact issue? Could you please elaborate more? Like at what point does it fail to transfer?

      BTW, I never asked. Before you used this procedure to root your G955U, what firmware was it running?

    4. So, when I want to send photos to my friend’s Samsung phone, when in the gallery I click Share, but there is no menu to share via WiFi Direct. because in the previous firmware or what we call Samsung’s original firmware, there is a share menu via WiFi Direct..
      but in this firmware, I didn’t find the wifi menu directly when I clicked the share button on my photo. will send through the gallery.

      You can try, the way is:
      open the gallery -> click on the photo you want to send -> click share at the bottom -> many options will appear, but there is no direct wifi option.

      or it seems that in Nougat there is no method of sending images via Wi-Fi directly, hmm I tried to investigate hehehehe

      Before I rooting my phone, I used the G955USQU5CRK1 / G955UOYN5CRK1 (XAS) firmware Oreo 8.0

      thank you my friend, your help is very meaningful to me. I am very happy to be able to continue discussing with you

    5. I think may be that is because of the old Samsung gallery app that’s present in Nougat. Have you tried updating the Gallery app to the latest version via Play Store? Or try downloading the latest APK from here and install it.

      Then make sure to force-close the gallery app and try again. See if it helps?

    6. Hi bro..thank you for your help, the condition is still the same, wifi direct is still not appearing, maybe this is one of the bugs in this firmware, I’m fine, thanks for helping me..thank you brother..

    7. Yes. May be it is a bug with the firmware. I will soon be re-writing this guide from scratch using the new EDL method that supports both V5/V6 bootloader and might also work on the regular Galaxy S8 too.

      I did the same for the Note 8 Snapdragon guide. A bit more lengthy process, but easy at the same time.

  33. Hey there great work brother i’ve flashed this frimware from my oreo 8.0 but after i installed a 9.0 pie frimware G955USQU6DSG7 .. whenever im opening download mode and starting the BL files to flash it ended up with leaving cs … Or. Fail (auth) .. what should i do .. i really need to root my device ..

    1. Hi Absar. That’s because, from BL V5 onwards, the method was patched and hence, it is failing to install. I will need to revise the tutorial with the new method that is confirmed to be working on both V5 and V6 BL versions.

      I suggest you wait till I update the guide with the new instructions and download links.

  34. Hey, is this possible with the SM-G955W model as well? I believe it uses the snapdragon still. Also, android 9.0 is current software on the Canadian S8+. Please get back to me when you can. Thanks in advance 🙂

  35. Hello, I need you to help me know if I can root my snapdragon S8+

    I can’t seem to upload a pic of my software information but here it is

    One UI version:1.0
    Android version:9
    Baseband version:G955USQS6DSH3

    With this info can I use this post’s files to root my phone?
    Thank you in advance

    1. Hi Erick. No, this method does not support V6 BL (You have it installed).

      However, there is a working method that supports both V5 and V6 bootloaders. I will need to re-write the instructions from scratch for that. It may take a week to get it fully done. If you’re fine by it, then please be patient.

      In case it’s urgent, then the method is the same as for the Note 8 Snapdragon. If you’re in a hurry, you can download the files from here and follow the instructions mentioned in the Snapdragon Note 8 root guide.

  36. I have a Sprint locked S8 Plus model SM-G955U software ver G955USQU6DSG7 hardware ver REV1.0 CSC G955UOYN6DSG7 AP/CP G955USQU6DSG7 ..BL6 if I am reading the numbers right. Will the BL5 files work..I am guessing no. Do you have BL6 files or am I SOL? What are my options for rooting?

    1. Hi. I am aware that BL V6 patches the method for the Note 8. So I believe the same might have happened to the S8+. But I am yet to confirm. When I do I will be updating this post.

      For the SD variant, I don’t think there’s any other method that would work. This is the only possible method to root.

    2. This method didn’t work for V6. Are there any files coming soon to rescue folks on V6? Thanks.

    3. Hi Lery. Yes, this wouldn’t work for neither V5 or V6 BL. I am almost done finishing the Note 8 Snapdragon post that supports V5/V6 Bootloader versions. I will do the same for this tutorial too. Just give me some time.

  37. I currently have a tmobile sm-g955u, baseband v. g955usqs6dsg4. Is there a root for this? The reason I’m trying to root my phone is because my phone no longer connects to the cell network. I can only make phone calls over wifi and send texts to certain ppl over wifi. My sim works in other phones so I know its not my sim. I’m not sure if rooting would help but I figured it’s worth a try since I’ve done all the network resetting and wiped the phone. Any help on the issue would be great since I don’t really have a fully functional phone. Thanks in advance!

    1. Hi Andy. I have recently updated the guide and it should now work with BL V6 (which you have).

      However, I wouldn’t recommend jumping straight to rooting as a solution to the problem you’re facing. Have you tried installing the stock firmware via Odin again?

      BTW, did you previously installed the Pie One UI beta manually back when it was being tested? If I remember correctly, the beta required you to flash a specific firmware with DBT CSC. It could be the case that you flashed that firmware and changed your firmware’s CSC, which could be causing the issue.

  38. will i have the all apps and features like the official ROM of android 7 or i will have the ROM without apps and services and will i have the iris scanner and face unlook or no

  39. i installed rooted firmware succesfully on my s8 plus sm g955u now i want to install original firware android 7 how can i do that i tried to flash orignal firmware but everytime odin show FAIL msg . what should i do now

    1. Hi Abdul. You cannot flash official Nougat firmware. That’s because Nougat firmware has a bootloader version that is lower than the Pie/Oreo firmware that was installed on your phone, prior to this procedure.

  40. Hi, I really need your help. I tried to root my phone using this method. But after the first stage, flashing BL, my phone just shut down, and wont turn on, and not responding in any button command (it’s now unable to enter download mode or recovery mode). It is just blinking a horizontal line on the screen while I try to enter download mode. Previously it was using G055USQU5DSC1. Please help me.

  41. Hi,

    everything worked like a charm on a S8+ canadian version (Bell) except the calling options on the phone apps are limited. I have no conference call options and when I am on the line the keypad is not working ( like I cannot enter a code when I am in my voicemail. Tried truecaller with the same results, I wonder what can cause this behavior, do you have any ideas ?

  42. Hi, I’m trying to get some kind of stock, that will allow my phone to be credited by my carrier. I have an S8+ BASEBAND is G955USQU5CRK1. I followed these steps to get Nougat 7.0 and root access. My S8+ is tied to AT&T, but with the bootloader Version 5, is there any stock of Oreo or Pie that I can put on my phone? I haven’t been able to find an AT&T US firmware Version 5 that I can install. Any help would be greatly appreciated. Thanks in advance, and keep up the great work!

    1. Hi. I think you should be able to flash the Pie firmware from S8+ G955U (USC). But to just be sure, I want to verify the CSC of the firmware installed currently on your phone. Please open the dialer app, enter *#1234# and let me know what it shows on the screen.

    2. We’ll have to go another route to confirm my firmware Version because the *#1234# gives me an error. What other information would you need. Currently I’m on USA AT&T Carrier. I rooted my phone using method from this post. Android Nougat 7.0 security patch Feb 1, 2018. Samsung experience 8.1, Baseband G955USQU5CRK1, Build G955USQS2BRB1 Service provider SW version.

    3. Hi again. Just for a bit more confirmation, download and install the PHONE INFO app on your phone and share a screenshot of the ‘FIRMWARE’ tab in it.

    5. Okay. I think it’s safe to flash the latest Pie firmware from the USC region. You can download it from here or use SamFirm Tool. For latter, enter the model as “SM-G955U” and region as “USC”.

    6. Hello,
      Hey your advice worked like a charm, for reverting my phone back to stock V9 Pie. I have no further questions, I just really want to thank you for all of your help and hard work. You’re AMAZING!!! Anyone reading this, let me say this guy is the “REAL DEAL” a genius, and extremely knowledgeable. He will not steer you in the wrong direction! Thanks again for all you’ve have done for me. You’re the BEST!!!

    7. Hi again. I am glad that this worked for you.

      I can’t tell how happy I am reading your last comment. For the first time, I don’t have “words”. Couldn’t thank you enough for it. But I would like to let you know that it made my day! Thanks and hope to see you around.

    8. Hi Dhananjay,

      I have a SM-G955U with the same exact specs as ART posted on July 14th, 2019 except that I’m on Verizon and the phone was originally on Sprint, so it’s obviously SIM unlocked. I don’t know if it is bootloader unlocked, but it boots up (every time) with a splash screen that says [SAFESTRAP: DISABLED] and offers me a choice of booting to Recovery {Safestrap 4.10 (TWRP v3.3.1-0)} or Continuing to the Rooted Nougat OS.

      For whatever reason, I can’t enable Advanced Calling on this phone as-is. I can put the SIM into an S10 or an S5 (rooted) and Video Calling works perfectly so its not Verizon or my plan. I was thinking that upgrading the OS to Marshmallow or Pie might solve this problem. After reading these comments on this method, I wonder if you think it would solve my problem of if I should use a different ROM?

    9. Hi Guido. Did the ‘Advanced Calling’ feature work on unrooted Nougat OS before?

  43. Hey, thanks for the root method. Successfully rooted. I have a us based unlocked phone originally from T mobile but I have a sprint sim right now on my phone. Was wondering if you knew of any custom Roms that I could flash now? Everything I’ve searched shows bootloader 3 or less can’t find anything for bootloader 5. My version I guess is G955USQU5CRK1. Thanks again!!

    1. Hi. It depends on what you want. The Samsung version is clean Samsung Experience without Google Apps, and the other one comes with Google Apps. All your choice, my friend.

    1. Hi. What’s the current baseband version of your device? You can only downgrade to a firmware whose bootloader version matches with the current version installed on your phone.

  44. Is there a way to revert the phone back to stock setting and re-root? Baseband Version is SM-G955USQUCRK1 is it possible to return phone back to a rooted G955USQS2BRB1? Any direction you can give me on this would be greatly appreciated. Thanks ahead of time.

    1. Hi ART. Could you please reconfirm the baseband/software version installed on the phone? I believe you missed a letter or two in this “G955USQUCRK1”.

    2. Hi Jonathan. Root with Android Pie is not possible for the Snapdragon variants. Although, you can still install Safestrap recovery to make modifications.

      If you really need root, then you will be forced to use the pre-rooted Nougat OS.

    3. Sorry the baseband is “G955USQU5CRK1”. I was wanting to know it there was a way to install “unrooted” original Nougat 7.0 Stock? I originally had OREO installed, then followed the ROOT procedure you provided (worked like a charm by the way), wanting to get an S10+ but AT&T wont credit me for my existing phone because it’s rooted.

    4. Hi. I don’t think you can install stock Nougat, considering the BL version on Nougat was v1 and the one you currently have is v5.

      Could you let me know to which carrier is your S8+ branded to?

    5. At&t is the carrier. I would be fine with Oreo or Pie. But I can’t find anything with bootloader Ver 5 and my carrier. Any help would be greatly appreciated.

    6. Yes. Even I tried searching for Pie/Oreo firmware for S8+ G955U with AT&T. The only one I could find is Nougat and it would not be possible to install that. Even I tried with SamFirm tool but no results.

      Could you please go to the dailer app and enter *#1234#? Share a screenshot of that screen with me.

    7. hi there, i never rooted my s8 plus sm g955u sprint version and never get update till last 2 years. today i downloaded android pie firmware from sammobile for same model and installed on my s8plus it works like a charm.
      no idea will it work for rooted s8 plus or not

  45. Hola amigo , el programa se me queda atascado cuando le pongo el AP en:

    Firmware update start..

    Y arriba dice TZ y no avanza la carga

  46. Hey im afraid i didn’t get the reply . My questions is that i accidentally uninstalled super su app in its setttings and when now when im installing it it was showing root occupied then i flash super su zip from recovery but no super su showed up and when i try to install the apk file it shows the error ” root undedected” now my question is there any way to root it again or i have to install the frimware again .. ❤️ great work tho ❤️ thanks

    1. Hi again. In this situation, I would have recommended you to flash the SuperSU zip through recovery again, and install the SuperSU APK if required. But I now know that you have already tried that and failed. So, this wouldn’t work.

      So, the last resort is to install the firmware again.

      And yes, thank you for the kind words! I am glad this tutorial proved useful to you. 🙂

  47. HELP
    Stuck on step 11, phone says downloading but the indicator hasnt moved in ovee 2 hours. The phone says do not turn off, and Odin(princecomsymodified) v 3.12. What do I do. What happens if I turn the phone off or disconnect from pc? I’m in panic mode please help soon. Thanks ahead of time.

    1. Hi. Simply force-shutdown the phone, don’t worry, everything is alright. Once you have shut it down, reboot back into the Download Mode and try again with Odin v3.13. Let me know how it goes.

    2. Hey radhav i accidentally uninstalled super su app from the its settings .. now whenever i wanna flash it from recovery it successfully installed there but its not showing in when i boot up the phone.. installed super su apk but whenever i open it up it shows ” root not detected ” .. is there any solution for it ? Or i have to reinstall the whole frimware again?

    3. Hi. I believe you completely uninstalled SuperSU from the ROM. To fix this, simply re-flash the whole ROM again.

      Also, don’t forget taking a backup first.

    4. Wow! 1st let me just say that you are AWESOME!!! Everytbing worked like a charm and I really appreciate your help and quick response to my questions. Thanks for everything Dhananjay!!! I do however have one more question. Is there a way to return the phone to its factory state before this unroot method? I have/The SM-G955U version. Again, thanks for your help, and efforts I can’t tell you how much I really appreciate your help.

  48. Hey there .. thanks for the great tutorial .. just wanna ask that is there anyway to upgrade to oreo without loosing root privileges?

    1. Hi. I am afraid you can’t. Root can only be achieved on Snapdragon variants with Nougat.

  49. hello i have an sm-g955u onbaseband version : g955usqu5dsc1 android 9.0 and i cant even get past the ‘BL_V5_PART_1_AND_3.tar.md5‘ stage of this i get the result referenced below, i have tried using “Odin3_v3.13.1_3B_PatcheD”, “Odin PrinceComsy”, and “Modded Odin v3.13.1 Raymonf”. I am using the original wire aswell as a usb hub 2.0 as i read that usb 3.0 could cause issues. I have also tried jrkruse method to get on a rooted revision 5 bootloader found here: “” , and also tried the instruction by jrkruse foudn here: “” which only slightly varry from the instructions here. I am not sure what i am doing wrong any help would be much appriciated, thank you.

  51. Can i root from android pie? and you can upload video on youtube to help root. Sorry my english very bad

  52. Thank you for this.
    Everything worked just fine except for one minor setback.
    Using PrinceComsy A to Z Odin was stuck in step 11 writing the image (3 times different cable different port different computer). Resulting in warning screen when trying to boot to download mode. Through recovery I did a factory reset and wiped cache and then was able to get to download screen.
    The process went through using Odin Raymonf up to step 11 and then PrinceComsy for step 14 (Raymonf gave an error message for step 14).
    Unconventional way for doing this but the ROM is worth it.
    For SM-G955U (snapdragon) T-Mobile on Android 9 BL revision 5
    Thanks again.

    1. Hi YYerrati! Thanks for the feedback, I am sure that users will get a lot of help from this.

      BTW, instead of Prince Comsy’s Odin, did you give a try to Odin v3.13.1?

    1. Hi. That depends on the bootloader version your device have. Plus, note that this is a pre-rooted system image, so when you install it, your Android version will rollback to Nougat.


    1. Hi. Yes, you can as it is V5. Since the links in this post have not been updated yet, the file you’ll need can be downloaded from here. The instructions stay the same as above.

    2. thanks for your reply..just checking I wasn’t feeling.fine,sick but now am good. pls can this work on oreo or is for nougat…cos I hv oreo on my s8+ thanks for your help.

  53. Hi, i want to root my s8+ SM-G955U1, and i don’t know which Bootloader version i need to take to put on odin.
    Could you help me? (and sorry about my english) ^^)

  54. Thank you so very much. This is the most comprehensive root tutorial on the web hands down. After about 30 minutes of panic attacks and nail biting during the root process, it worked like a charm.

    1. Hi Brian! You’re welcome and thank you for such kind words. I am glad the tutorial was helpful.

  55. hi, this method has been a life saver. I was wondering however if there’s a way to switch to magisk instead? I love Xposed, but im looking to try out magisk if possible

    1. Hi Bryan! I am afraid it’s not possible to get Magisk running, since it needs a modified boot image to work, and for that, you would need an unlocked bootloader (Which is certainly not possible). Thus, you will only have to stick to SuperSU. But you can (May be, I am not fully sure) try installing Xposed as a standalone.

  56. The reason why I’m trying to root is to recover a deleted file from SM-G955U(AT&T) with Android 8 on it. Is there a way to root the device and not wipe all the data?

  57. Hi Dhananjay. When I go to settings -> Lock screen and security -> Face recognition, after trying to register my face it outputs an error message: “Face recognition not working, if it keeps happening, restart your phone”. What should I do?

    1. Hi again, Alex. I have researched the XDA thread for this issue, however since no one reported it, I am sure it’s not a bug. Have you tried repeating the procedure from scratch?

  58. Hello, it worked very fine, the only thing is that the face unlock function does not work, is there any fix for that issue?

    1. Hi Alex. It should work fine since the developer did not state any issue present related to that. What error does it show when you try to set up Face Unlock?

  59. Does this work on base band – G955USQS5CSB1? Just upgraded to the s10+ and was gunna root my s8+ for fun. Read that the price comy odin exploit has been fixed with the most recent update. Don’t want to brink a prefectly working phone if this doesn’t work. Thanks!

  60. If I use the pre-rooted image, will I be able to flash factory binary to the phone, so that I can change carrier information? Ever since I bought the phone and had T-mobile unlock my phone through their database, things went horribly wrong after putting in AT&T Sim. It basically changed the phone info, making it think it belonged to AT&T, but my main Sim is Mint Mobile (T-Mobile MVMO).

    1. Hi Miles. In that case, simply re-flash the stock firmware for T-Mobile and then re-root your phone using this process.

    2. How do I re-flash a stock firmware (ex. T-Mobile) if I wanted to go back to stock rom??

  61. Hi, So I did the root and it was successful, but I want to unroot my device now back to stock, how do I do that? I can’t seem to figure it out.

  62. Having the same problem others are having. I’m on bootloader 5 and trying to use the BL_V5_PART_1 file but odin will just end in “all threads completed (succeeded 0/failed 1) without the phone rebooting. I’m using the PrinceComsy odin, my phone is in download mode, and i’ve made sure i’m using the correct file. Help would be much appreciated

  63. I’m happy to say that I’ve successfully rooted my phone. Are there any roms that are compatible with this or will it revert my root?

    1. Hi Kuro! Glad to know that! I am not sure you will be able to install anything else apart from this. This is basically a pre-rooted system partition.

    1. Hi Indra. That could be depicted from the software version installed on your phone. Please open the dialer and enter *#1234# and let me know the exact details you see on the screen.

  64. Stuck at splash at boot. I tried the instructions provided, going to recovery mode, reset to stock, clear cache partition, rebooted, same issue. Tried 3 times! Any advice perhaps? Thank you in advanced!

    1. I believe V5 bootloader, but I used proper files. What I ended up doing, I think if I can remember correctly, is starting over, and upon first boot it said file system corrupt and asked me (in android window) to reset device, so I said YES, and it allowed me to setup as if it were a brand new phone and proceeded through setup. There were some errors connecting google at first if I remember correctly so I tried skipping passed it and linked it later without issues.

      I do wonder now – with this method being success for me, how to utilize the ROM1-4 slots? I tried researching and some say cannot use on this model: Verizon G955U due to bootloader.

      Here are my main questions for those slots:
      1 – Can you use any other version of android, rooted or non-rooted? As if I wanted to boot to ROM1 which is essentially copy of STOCK, and have root access, where as booting to ROM2 would be a build without root access for utilization of Samsung Secure Folder, Chase Pay/Samsung Pay, etc?
      2 – Can you refer me to a link which is a guide for how to properly utilize files during the installation phase of setting up ROM1-4? I tried and found that most files are image.7z and require BL_1 files to be used with ODIN, so that is OK if I also need computer during first time setup of each ROM slot, but really lost on how to actually proceed through the setup of each slot because I tried to do once and it said “NO OS INSTALLED” when booting after TWRP/SafeStrap reported successful flash of image to ROM1. To be fair, I was using completely different built ROM for ROM1 slot, Stock was rooted nougat where ROM1 was going to be non-rooted oreo.
      3 – With this solution installed, what is the correct process to restore from backup? I had backed up STOCK, couldn’t figure out how to duplicate STOCK to ROM so made my changes to STOCK, and this morning maybe one change too many before reboot and cannot get beyond lock screen, no response. I just went straight to try to restore, said error mounting at the end…

      Again, thank you in advanced for your time!

    2. Hi again! Glad it booted fine. Before I try and answer your questions, can you please tell me what you mean by “How to utilize the ROM1-4 slots?”. Did you mean using the DualBootPatcher to boot multiple ROMs?

  65. Hi I have a G955W and used this method to root. Phone seems to show model G955U in settings after root. Is there a specific method that I need to follow to unroot back to original firmware and G955W? I don’t seem to be able to simply flash original firmware with Odin and stock G955W firmware BL,AP,CO and CSC. Any help on this would be super appreciated. Thanks.

    1. Hi Michael. What error does it show when you try to flash G955W firmware using Odin?

    2. Hi,
      Thank you for the response. Sorry, I should have given you more information when describing the issue.

      When I try using the PrinceComsy version here is what I am getting in the log before a window pops up saying Odin Downloader has stopped working.:

      Odin engine v(ID:3.1203)..
      File analysis
      Set PIT file..
      Get PIT for mapping..
      Firmware update start..
      {Then the Window Pops up “Odin stopped working”}

      I am using the stock firmware for my device and carrier. (downloaded from I verified that it was the correct baseband version (G955WVLS5BSA1) as was originally on the phone. I have tried using ODIN ver 3.13.1 as well and I get the “FAIL! SHA256 is invalid” error.
      Both versions are giving me the blue highlighted 0:[COM4] indicating that Odin can see my mobile device so I think I have good drivers on my windows machine.
      I am selecting all the files from the firmware (BL , AP , CP , CSC) all checked off and all finish checking MD5 successfully in Odin when added.

      I have ensured that “Auto Reboot” and “F. Reset Time” are the only things checked off in the options tab as well.
      Not sure what could be wrong… any help would be greatly appreciated.

    3. Hi Michael. Don’t be sorry about it. Your reply has given me all the necessary details. I want you to download this patched version of Odin 3.13.1 that skips the SHA256 checks. Please retry flashing the stock firmware via this and let me know if it succeeds.

    4. Hi Dhananjay,

      Awesome! Thank you so much for your help. It worked perfectly!


    5. S8+ snap của tôi đang là android 8.0 nếu giờ root thành công theo samfail thì sẽ về hệ android 7.0 à

    6. Hi Thoung. Yes, the method will put Android Nougat on your device. There’s no way to root the Snapdragon Galaxy S8 Plus on Android Oreo or Pie.

    7. Hi Michael!

      Did you really succeeded in rooting your SM-G955W ? I have same phone, same baseband version than you ( G955WVLS5BSA1) and I’ve tried many methods to root my S8+ and so far, nothing works.

      I might give it a try.


    8. Hi Audrey,

      Yes I have rooted my phone following the method here. I can verify that it does work for the SM-G955W with this baseband version.

    9. Hi again, Michael. I am glad it worked. I have updated the Odin article with the link to the patched version as well.

  66. Hi, I was wondering if there is a way to use SuperSU in SBIN mode when using this root method? I would like to use SUHide and all the information I have found indicates that SuperSU needs to be running in SBIN mode to use SUHide. Thanks for the great posts and information. Very well done.

    1. Hi Mike. First off, thank you for your appreciation.

      Since the method uses the latest SuperSU release, then I am quite sure that SuperSU will run in SBIN mode.

  67. Would just like to say thank you. This worked perfectly. Took maybe 10 mins before I could use my phone again.

  68. Have not rooted a phone in over three or four years. Your guide made rooting my Samsung s8+ one of the easiest tasks I have ever done with rooting. And no tripping Knox! How about that. Thank you for the super imformative guide. Worked perfectly. Only thing I had a problem. With was that Heliim app back up program you linked to in your article. Thing kept popping out half way through backing up.

    Question: I keep getting a 1.5gb OTA pushed to me, I assume Oreo from the Samsung servers…how to I avoid having it continuesly try and download (and eventually try and install)?

    1. I have the same device and had the same issue. Use the PrinceComsy Version. Working like a Charm

    2. Hi Bilal. Thanks for pointing that out. I have updated the instructions accordingly.

  69. I really thank you for this wonderful post. It really helped me to downgrade from crap oreo to nougat. As per bugs battery only charges upto 80 %. Sometimes brightness gets low and does not work while charging. And very random sometimes menu lags but locking and unlocking again resolves lagging. I just want to ask about battery whether my phone is really using 80 % or its just showing 80 but actually using 100% ? Please reply me back. Thanks again.

  70. I have a question that I can’t find the answer to, PLEASE HELP ME, I bought a Galaxy s8+ running oreo and carrier unlocked the phone. It was a Spectrum Mobile branded phone and activated it on T-Mobile. The problem is that there is no wifi-calling because it is not a T-mobile phone. I am on BL 5 and I want to flash the stock T-mobile firmware so I can use wifi-calling. Without wifi-calling I get no signal at work or at home and that defeats the purpose of even having a phone. If you have any workaround that you know of or I can speak with you DM or phone that would be awesome. Every thing about the phone works great but it still has the Spectrum boot animation and the Spectrum apps. I installed the T-mobile sim , factory reset and then booted the phone hoping that the T-mobile sim would make the changes but its a no go.

  71. I thought when I went with the GS8+ I would not have any need to root. After a year, I have decided to give it a try, mainly to use TBU. A couple of questions:
    1. My current baseband version is G955U1UEU5CRK3. There is a software update pending with a baseband version G955U1UES5CRL2. Safe to assume either version is okay for rooting (using bootloader v5) and therefore I can take the update prior to rooting?
    2. Once rooted, do I need to “block” any future OTA updates to hold root?
    3. Is there currently a proven process for returning to the unrooted condition?

    Your tutorial is really well written and clear. I appreciate your effort.

    1. Hi Don! It’s wise of you to appreciate it! Just out of curiosity, what is TBU that you’ve referred to here?

      As for your questions:
      1)Yes, your phone is rootable and there’s no benefit of taking OTAs, the method pushes your system back to an older firmware.
      2) This will block future OTAs
      3) You can always flash back the stock firmware using Odin.

      Over everything, I would like to know the reason for rooting first. So, if there’s an alternative to do the same without root, then that is what I would recommend.

    2. Thanks for the information. By TBU, I meant Titanium backup. Probably not a real good reason to root. Auto backup of apps/data to Samsung cloud seems to work well. I assume Samsung has yet to block your method with the latest clr2 update.

    3. You’re welcome, Don! Yeah, even I think likewise. It’s best to keep the software up-to-date unless you have a strong reason for rooting.

      The method can’t be blocked, it just downgrades your system to an older firmware that was rootable. Yes, if the bootloader version upgrades to V6, then this method would be unusable.

      I wish Google soon pushes app/data backup service to its phones as well (Like my Pixel 2 XL/3 XL). I wouldn’t blame your reason to root, some people do it for TBU. But if there’s an alternative like Samsung Cloud, then I wouldn’t feel the need to root.

    4. Well I got in a rush and soft bricked my 8+. Insurance sent me a brand new 8+. Didn’t think they would so I jumped the gun and bought one myself. Now I have two phones so I can afford to try this again. I “think” I caused the problem when I was downloading the AP file. Question:
      Para 11 says “the phone will boot automatically. When it does,..enter download mode”.What is the timing on this? Do I take action to enter download as soon as it starts to reboot or do I wait for it to startup? What if it doesn’t reboot. Is this where I would go to recovering and clear cache, etc.”

      This time I have a stock firmware on my sd card so I am hoping if all else fails, I can enter recovery and reboot from the card.

      Thanks for all you help.

  72. Thank you very much! This is the simplest guide I could find and I can confirm that this works for Canadian model of S8+ G955W.

    Thank you once again! Cheeers!

  73. Hi
    Galaxy S8+
    Android 8.0
    Build G955USQU3CRD4
    Will I be able to root this device safely? and backup my data with samsung smart switch then put it back?

  74. mine is G955USQS5CRI4, and i always get this error (using BL_V5):
    Odin engine v(ID:3.1301)..
    File analysis..
    Total Binary size: 199 M
    FAIL! SHA256 is invalid
    All threads completed. (succeed 0 / failed 1)

  75. ATTENTION ALL: if you happen to ignore and try to use magisk with this exploit anyways, and find yourself facing a soft brick Reflash the BL_V4_PART_1 using the 3.13 Odin *PRINCE COMSY VERSION*

    that is all

    1. Thanks, Mike! I am sure this info shall prove very helpful to others here.

      EDIT: I have modified your comment slightly to reflect our Comments Policy.

  76. I have Oreo (I think, V 8.0.0). Can I root my g955u with this? if not is there an easy way to go back to nougat? First time rooting a phone just need some pointers. Thanks in advance

    1. if you read the tutorial it says it is supposed to say fail, and it will eventually restart. That is where i am having my issue it says fail but it is not restarting on its own. I wait for over 10 minutes and no restart them i did “Note: If the phone gets stuck on boot animation for more than 10 minutes, reboot to recovery mode (Volume UP + Bixby + Power) and perform a wipe data/factory reset, followed by a wipe cache partition, and then reboot the device.” and tried again and same thing …

    2. Hi, Shadokeeper. By any chance, is the ‘Auto Reboot’ option unchecked in the ‘Options’ tab of Odin tool? Please check and let me know.

  80. my phone is “g955usqu5crk1” lasted update
    will this way work for me?
    can you record video doing this way 😀

    1. Hi Saleh, yes, it will work for your phone. However, note that the this is a pre-rooted Nougat ROM and not Oreo. So, you will have to compromise with the previous Android version if you really need root.

    2. Hola que tal solo me interesa el root para liberar mi dispositivo con la versión antes mencionada, después de eso podría cargarle el twrp y poner una custom rom o volver a android 8.0 oficial

    1. Hi. This is for S8+ with BL version 5 or 4. Since yours is version 2, I suggest you go with PartCyborgROM that uses the same method. Please make sure to carefully read the whole thread and understand the process before you begin.

  81. So now I’m on nougat after successfully rooting thank you.

    But is there anyway to update to Oreo 8.0 while being rooted?

    Also I can’t use Snapchat unless I unroot and use magisk to hide the root from Snapchat is that correct?

    1. Yes, it should work. The CSC stays the same, only the system and bootloader partitions are modified.

  82. Aloha,

    I have a Samsung S8 Plus, G955USQU5ARF 8.0. Oreo on T-mobile. Was able to jailbreak it, but not successfully in rooting it. Is it due able an from where.

    Now, is jailbroken w/Samfail. Can It be rooted and from where….

  83. Also, since my phone is already running BL revision 2, won’t the SamFAIL PartCyborgRom method work for it? That method will work for the Snapdragon G955u running Android 8.0 and running BL revisions 1 & 2. I just don’t know if my security patch level from March 1st, 2018 possibly patched that exploit method? As far as I know, that root method was implemented December of 2017, but I don’t know if it was patched with the March 2018 security update or in a later security update. Or do you think I should try to update my phone and hopefully get BL revision 4 or 5 and then try this method here you have given?

    1. Hi again Tom, there’s something that I would point out here.

      Your S8+ is running Android Oreo and unfortunately, there’s no way to root it. The only root methods available, be it PartCyborgROM or this one, these are only for Nougat firmware.

      Since your phone is on V2, I suggest you opt for PartCyborgROM that supports V2 BL, but then it will take your phone back to Nougat.

    2. But I thought this article said that this root method works for both Nougat and Oreo?

    3. Scratch that. I just now realized you meant that it will take you from Oreo, back to Nougat, in order for root to work. I thought it meant root worked for Oreo also at first 😂 It’s been a long two days.. I apologize.

      Thanks for the help and guidance, I appreciate it! I’m entirely new to Samsung so this has been a bit of an adjustment. I’ve been on a rooted lollipop OnePlus X for nearly two and a half years now, so I haven’t been up on more recent developments like companies (or I should say, carriers) cracking down on bootloaders, just like I didn’t know that Samsung didn’t even use Fastboot lol.

      Anyways, thanks for the help and have a good one!

  84. My baseband version is: G955USQU2CRC5

    So I assume that I am on version 2, correct?
    So, is there a way to upgrade to version 4 or 5?
    I just bought this phone and it came with Android 8.0.0 already installed and the last security patch was March 1, 2018.
    But I do have software update/s available (I don’t know if there are multiple waiting behind one another or if it’s just one update). If I update, is it possible I’ll get one of the current revisions (4 or 5)?

    1. Hi Tom, yes you are right, the BL version of your phone is V2. Yes, once you start updating, you will reach V4 and then V5 BL eventually.

  85. Hi, if I don’t tick the re-partition then it says re-partition failed. However, If I do, it says it can’t open the specified file (Line: 1892).

    Model: G950U1UESCRF5

    I am also having troubles downgrading from 8.0 to 7.0 version for Android if you have any tips Thanks

    1. Hi Eric, at what step does this happen?

      As for downgrading, you cannot downgrade from 8.0 to 7.0 due to bootloader restrictions.

    2. It worked for me. I’m on an sm955u and I was able to downgrade from 8.0 to 7.0

    3. Hi Michelle, it will only work if both the 8.0 and 7.0 firmware have the same bootloader revision. I believe it was the same, in your situation.

  86. Is there a way to do this on snapdragon oreo with bootloader version 3? I tired using both v4 and v5 bl part 1 and obviously they failed.

    1. Hi Alan, I am sorry but it only works for BL v4 and v5. v3 is not supported.

    2. i did an upgrade on my phone and it is on version G950U1UES5CRF5, so the bootloader is now version 5, and when i tired the root odin fails on part 1 saying the re-partion operation failed. Am i missing something else?

    3. Please make sure that re-partition is not ticked under the ‘Options’ in Odin program.

    4. That’s odd. What do you see in the PIT menu that’s beside the ‘Options’ in Odin window? Also, did you choose any .pit file in Odin?
