Do you want to root your Snapdragon Galaxy S8 and S8 Plus? Here’s a quick and efficient tutorial to help you root Galaxy S8/S8 Plus Snapdragon using the new EDL method, provided by XDA developer jrkruse. The method works for SM-G950U/U1 and SM-G955U/U1 models sold in the US, and SM-G950W and SM-G955W models sold in Canada.
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 the current S9/Note 9 lineup. We have already seen root for the Exynos S8, and it is based on the standard rooting method involving TWRP and SuperSU/Magisk. But things tend to get a bit complicated when it comes to Snapdragon-equipped Samsung devices and rooting, largely due to the locked bootloader on the Snapdragon variants.
Root has been available for the Snapdragon models on earlier firmware builds via the SamFAIL exploit, which we also used to root Galaxy Note 8 N950U. But later revisions to the firmware and more importantly, the Bootloader version rendered the exploit useless. However, thanks to XDA’s Recognized Contributor jrkruse, we now have a working method to root Galaxy S8/S8 Plus Snapdragon with V5 and V6 Bootloaders.

Rooting Snapdragon Variants of the Samsung Galaxy S8 and Galaxy S8 Plus
Like I said earlier, rooting the Snapdragon variants of Samsung devices has always been a struggle for the community because of locked bootloaders. Unlike the Exynos variants, the bootloaders on the Snapdragon variants are not unlock-able. And hence, the generic method of flashing TWRP via ODIN and then rooting through Magisk would fail rigorously.
But it seems like the Galaxy S8/S8 Plus Snapdragon users are finally getting the desired attention from the root community. The Root for Galaxy S8/S8 Plus Snapdragon variant has been brought to the users by XDA RC and developer – jrkruse (Along with contributions from various other developers and XDA community members) through the new EDL Method. It will help you easily root your Galaxy S8/S8 Plus Snapdragon and install Safestrap recovery on it at the same time.
We have already covered a guide to root Galaxy Note 8 Snapdragon using the same method. The only difference between both the guides is the files used during the process.
Now before you go ahead and follow the instructions, take a look at the following pointers to debrief yourself with the method that will follow.
- This method will only work if your phone is using version 5 (V5) and version 6 (V6) bootloaders.
- Root on Android Pie is not possible. The procedure involves installing the Android Pie Safestrap ROM. Once that is installed, you can use Safestrap to apply modifications to your phone by flashing zips or making modifications to the system partition.
- If you really need root, you will further need to flash a pre-rooted Nougat system image on your Snapdragon Galaxy S8/S8 Plus. This means you will be forced to use the Android Nougat OS for root, so no Pie or Oreo.
- The supplied Nougat system image is pre-rooted with SuperSU and has Flashfire and Safestrap recovery pre-installed.
With that information at hand, head over to the instructions to root Galaxy S8/S8 Plus Snapdragon.
Supported Devices
The following devices with the corresponding 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.
- Samsung Galaxy S8 with model number SM-G950U, SM-G950U1, and SM-G950W are supported.
- Samsung Galaxy S8 Plus with model number SM-G955U, SM-G955U1, and SM-G955W are supported.
This process will work regardless of whether you are 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 V5 or V6.
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 “G955U1UEU6DSJ4”. The “U6” here denotes the bootloader version, which is V6.
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 TheCustomDroid.com, or any of its members shall not be held responsible for any damage caused to your device during or after following the process.
Prerequisites
- 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 and Qualcomm HS-USB QDLoader USB Drivers on your PC.
- Also, download the latest Android Platform-tools package, extract it, and add it to your Windows PC PATH (Environment Variable). Alternatively, you can also use Minimal ADB and Fastboot that automates the whole process for you.
- 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!
Once you have everything set up, you can easily root Galaxy S8/S8 Plus Snapdragon. If you’re new to the whole rooting scene, make sure to take your time and understand each and every step before you execute.
Downloads
Make sure to download the files according to the bootloader version your Galaxy S8/S8 Plus has.
Galaxy S8 (SM-G950U/U1/W)
- V5 Bootloader
- V6 Bootloader
Galaxy S8 Plus (SM-G955U/U1/W)
- V5 Bootloader
- V6 Bootloader
Steps to Root Samsung Galaxy S8/S8 Plus Snapdragon Variant
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: Flash Combination Firmware File
The first step in the process is to flash the Combination Firmware on your Galaxy S8/S8 Plus corresponding to the bootloader version. To do so, follow the steps listed below.
- Download the Combination Firmware package (COMBINATION_FA70_***********.rar), corresponding to the bootloader version of your Galaxy S8/S8 Plus.
- Extract the downloaded RAR file to a suitable location on your PC.
- Launch the Odin Flash Tool on the PC by double-clicking on the ‘Modded Odin v3.13.1 Raymonf.exe’ executable file.
- Click on the ‘AP’ button in Odin and select the extracted Combination Firmware file (COMBINATION_FA70_G95********.tar.md5).
- Ensure that ‘F.Reset Time’ and ‘Auto Reboot’ is checked in the ‘Options’ tab of Odin.
- Now power off your Galaxy S8/S8 Plus completely.
- Boot your device into Download Mode. To do so, hold the Volume Down + Bixby + Power button simultaneously until you see the warning screen. Then tap the Volume Up button to enter Download Mode.
- While your S8/S8 Plus is in Download Mode, connect it to the PC using the USB cable.
- The ID:COM port in the Odin window should light up.
- Finally, click on the “Start” button in Odin to flash the Combination Firmware file on Galaxy S8/S8 Plus Snapdragon.
As soon as the flashing process finishes, your device will boot into the test OS (See the image below).
Step 2: Boot Samsung Galaxy S8/S8 Plus Snapdragon into EDL Mode
The next step is to reboot your Galaxy S8/S8 Plus into EDL mode correctly.
- With your Galaxy S8/S8 Plus booted into the test OS, swipe down from the notification panel and tap on the settings icon.
- Then enable USB debugging on your device.
- Connect your device to the PC (with USB debugging enabled) using the USB cable.
- Download ‘G95*U_Full_EDL_V*_Pie_Safestrap.rar’ file according to your Galaxy S8/S8 Plus’ model number and bootloader version.
- Extract the downloaded file on the PC.
- Double-click on the ‘Reboot_EDL.bat’ file to boot your Galaxy S8/S8 Plus Snapdragon into EDL mode.
- If you see the “Allow USB debugging” prompt on the device’s screen. Simply tap on “OK”.
Your phone should now reboot and enter the EDL Mode. The device’s screen will turn black and this is what EDL mode looks like. So, do not disconnect the device and head over to the next 3rd step below.
Step 3: Install Android Pie Safestrap ROM (System image) using ‘G95*U_Recovery.bat’ File
- Go to ‘Control Panel’ > ‘Device Manager’ on the PC and ensure that your Galaxy S8/S8 Plus is being detected as ‘Qualcomm HS-USB QDLoader 9008’.
- In case your device is recognized as ‘QHUSB_BULK’, make sure that you install the required drivers on the PC.
- Now, open the previously extracted ‘G95*U_Full_EDL_V*_Pie_Safestrap’ folder and double-click on the ‘G95*U*_Recovery.bat’ file.
- A console window will open on your PC.
- Simply enter the COM# (where “#” is the number) port number for your Galaxy S8 as shown in the console window.
- The Android Pie Safestrap ROM (System.img) will be installed on your device.
The flashing/installation process can take some time and the console window may appear to be hanged. This is normal behavior, simply wait for it until finished. Once the Android Pie system image has been successfully installed, head over to the next step below.
Step 4: Install Android Pie BL and CSC using Odin
- Force-reboot your Galaxy S8/S8 Plus Snapdragon into Download Mode.
- To do so, hold the Volume Down, Bixby, and Power buttons. Once the warning screen appears, press the Volume Up key to enter Download Mode.
- Make sure that your phone is connected to the PC while it is in Download Mode.
- Double-click the “Modded Odin v3.13.1 Raymonf.exe” file to launch the Odin Flash Tool.
- The COM port in the Odin window should light up.
- Ensure that “F.Reset Time” and “Auto Reboot” are selected under the “Options” tab in Odin.
- Click on the “BL” button and select the Android Pie BL file (BL_G95*U******.tar.md5).
- Next, click on the “CSC” button and select the Android Pie CSC file (HOME_CSC_OYN_G95*U_CACHE_V*.tar.md5).
- Finally, click on the “Start” button to install the Android Pie BL and CSC files on your device.
- Once the flashing process finishes, your Galaxy S8/S8 Plus will boot directly into the stock recovery mode.
- Now, it is important to perform a factory reset. To do so, use the Volume keys of your device to highlight the ‘Wipe data/factory reset’ option and press the Power button to select it.
The first boot might take some time, but that is normal. When your phone boots, it should be running the Android Pie ROM.
Step 5: Boot Galaxy S8/S8 Plus Snapdragon into Safestrap Recovery
Now, it is worth noting that unlike the stock recovery, the Safestrap recovery is not installed on your device’s /recovery partition. It is rather loaded directly from the bootloader. This means you will need to flash the Safestrap Recovery file to the Galaxy S8’s BL slot using Odin, every time that you want to boot your device into it.
To boot your Galaxy S8/S8 Plus Snapdragon into Safestrap Recovery, follow the instructions below.
- Power off your device completely.
- Hold the Volume Down, Bixby, and Power buttons together until you see a blue-colored warning screen.
- Simply tap the Volume Up button to enter Download Mode on your Galaxy S8.
- Connect your device to the PC while it is in Download Mode.
- Launch the modded Odin Flash Tool by Raymonf on your PC.
- Click on the “BL” button and select the “BL_ENG_BOOTLOADERS_SAFESTRAP_G95*U_V*.tar.md5” file.
- Ensure that “F.Reset Time” and “Auto Reboot” are selected in Odin’s “Options” tab.
- Finally, click on the “Start” button to flash the file.
Your Snapdragon Galaxy S8/S8 Plus should now boot into Safestrap recovery, which is based on TWRP v3.3.1-0 and offers the same UI. You can now use Safestrap it to flash mods, backup/restore a NANDroid backup, flash firmware image files, and more.
To exit Safestrap, go to ‘Reboot’ > ‘Download’ to reboot your device into Download mode and re-flash the Android Pie BL file (BL_G955*USQU****.tar.md5) using Odin.
From here on, you have two options:
- First, either stick with the current Android Pie setup and make desired modifications to the phone’s software using Safestrap recovery. This will allow you to enjoy Android Pie and One UI features, along with a more recent security patch.
- Or, proceed with the instructions to Step #6 below and flash Pre-rooted Nougat System Image to root Snapdragon Galaxy S8/S8 Plus. Choose this option if you really want to gain root access to use root-enabled apps or install audio mods like ViPER4Android, etc. The two major disadvantages with this option are that you will be forced to use Android Nougat-based Samsung Experience OS (instead of One UI) and will be stuck with an even older security patch.
The decision is solely yours to make as per your requirements.
Step 6: Install Pre-Rooted Nougat System Image to Root Galaxy S8/S8 Plus Snapdragon
To root, you will first need to download the pre-rooted Nougat ROM, extract the ‘system.img’ file from it, and then flash the system image using Safestrap recovery. You will further also need to flash the Nougat-compatible Safestrap recovery (via Safestrap itself) and then flash the fingerprint and face unlock fix (via Odin).
- Download the following files on your PC:
- Rooted_G950USQS2BRB1.rar (Galaxy S8) | Rooted_G955USQS2BRB1.rar (Galaxy S8 Plus)
- Safestrap-4.10-B03-DREAMQLTE-NOUGAT.zip
- BL_G950_FINGERPRINT_FIX_V6.tar.md5 (Galaxy S8) | BL_G955_FINGERPRINT_FIX_V6.tar.md5 (Galaxy S8 Plus)
- Extract the “system.img” file from the downloaded “Rooted_G95*USQS2BRB1.rar” file using an archive utility (like 7Zip, WinRAR, etc).
- Transfer the extracted “system.img” and “Safestrap-4.10-B03-DREAMQLTE-NOUGAT.zip” files to your Snapdragon Galaxy S8’s storage.
- Now boot your device into Safestrap recovery by following the instructions in Step 5 above.
- In Safestrap, tap on the “Install” button and then on “Install Image”.
- Navigate to your phone’s internal storage and select the “system.img” file. When prompted to select the partition, select “System Image”.
- Swipe the button on the bottom to flash the pre-rooted Nougat System Image on your Galaxy S8/S8 Plus Snapdragon.
- Now go back to the recovery’s main menu and press the “Install” button again.
- Select the “Safestrap-4.10-B03-DREAMQLTE-NOUGAT.zip” file and flash it.
- Once both the files have been flashed, go to the “Reboot” menu in Safestrap and tap on “Download” to reboot your device into Download Mode.
- Connect your phone to the PC while it is in Download Mode.
- Launch the modded Odin Flash Tool by Raymonf and select the “BL_G95*_FINGERPRINT_FIX_V6.tar.md5” file in the “BL” slot.
- Finally, click on the “Start” button to flash the file.
As soon as the process finishes, your Galaxy S8 device will reboot into the OS (system).
Important: Now, it is very important that you boot your Snapdragon Galaxy S8/S8 Plus into recovery mode and perform a factory reset. Or else, the booting process will be stuck on optimizing apps.
To do so, power off your phone first, and hold the Volume Up, Bixby, and Power buttons together to enter recovery mode. Then use the Volume buttons to select the “Wipe data/factory reset” option and press the power button to confirm.
Great! You have just been able to root Galaxy S8/S8 Plus Snapdragon using the new EDL method. If you come across any roadblocks during the process, drop a comment below, and we will be more than happy to help you out.

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.
Do I need to flash this BL_G950_FINGERPRINT_FIX_V6.tar.md5, out of caution because Im on V5.
Hi Fadli. Yes, you need to flash it. Don’t worry about the filename.
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
Hi Bayu, is it showing a black screen with or without the notification LED glowing?
Can magisk root be installed using this method?
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
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.
my phone was formated so I need to recover my files
what is Bootloader v5 or v6
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 ❤️
Like can i change my imei number when i put my mobile to test os screen? Without gaining root ?
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?
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 ..
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.
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
Hi Ermias. That’s correct. That’s the file mismatch error you’re getting.
Is your phone the G955U model or the G955U1?
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
Hi Antonio. Please open the dialer on your phone and enter *#1234#. Let me know the software information it shows on the screen.
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
I have a sm-g950w but idk the bootloader version…
My baseband version is G950WVLS7CSK1
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.
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?
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?
Does VoLTE work ?
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.
Oh one more thing. Making backups and restoring backups. How wold one do that without loosing safestarp ?
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.
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
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. 🙂
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
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.
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.
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
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.
Can I root with a bootloader: G955U1UES7DSK4
Android 9.0
SM-G955U1
Thank
Hi Herguri. No, the V7 bootloader is not yet supported.
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
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).
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!
Hi Pagani. There’s no confirmation by the developer on V7 yet. But I am sure it will be supported soon.
Hi,
My baseband version is: G955USQS7DSK2
So I assume that I am on a BL v7, correct?
Does this method work for BL v7?
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.
I tried several times but it didn’t work use odin v3.13
one : 1.0
AV : 9
BV : G955U1UES6DSJ1
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.
Still waiting 🙁
Hi Frnk. Sorry to keep you waiting. I am trying my best to complete it. Have a lot of impending posts to do.
Hi Frnk. The guide has been updated to reflect the new instructions along with the corresponding files.
Is the root for V6 available??
Yes, however, this post is not yet updated with the latest method and files. Please check this XDA thread for now.
Hi Mitch. The guide has been updated and should work for V6 bootloader now.
Yeah. I went through the process twice. It’s stuck on the wifi setup. It says “turning on wifi”
Hi tj15401. Which bootloader was your phone using before you started with the instructions?
I used the Note 8 method and everything seems well except that wifi will not turn on…any suggestions?
That’s great, TJ15401! Did you perform a factory reset after performing the whole procedure?
Can I root with a bootloader: g955usqu6dsh8
Android 9.0
G955U
Hi Tyler. Yes, you can root using this method.
Can I use this for G955USQU6DSG7?
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.
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
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.
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
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.
Hi bro.. this method is successfully ..im 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
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.
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
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?
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
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?
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..
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.
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 ..
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.
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 🙂
Hi. Is it the Chinese/Hong Kong variant?
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

With this info can I use this post’s files to root my phone?
Thank you in advance
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.
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?
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.
This method didn’t work for V6. Are there any files coming soon to rescue folks on V6? Thanks.
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.
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!
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.
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
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
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.
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.
Baseband version is G955USQU5CRK1
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 ?
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!
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.
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.

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.

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”.
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!!!
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.
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?
Hi Guido. Did the ‘Advanced Calling’ feature work on unrooted Nougat OS before?
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!!
hi bro Which file i should download Samsung Or google or both of them ?
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.
How do I unroot so I can have a clean stock 7.0 rom?
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.
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.
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”.
can i use this method to root my s8 plus running pie
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.
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.
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?
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.
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.
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

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
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. 🙂
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.
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.
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?
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.
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.
Do I download both the Samsung SamFail, and the google SamFail files or just one or the other?
Hi ART. Either of them, depending upon what you want.
Hey there .. thanks for the great tutorial .. just wanna ask that is there anyway to upgrade to oreo without loosing root privileges?
Hi. I am afraid you can’t. Root can only be achieved on Snapdragon variants with Nougat.
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: “https://forum.xda-developers.com/galaxy-s8+/development/root-t3909782” , and also tried the instruction by jrkruse foudn here: “https://forum.xda-developers.com/verizon-galaxy-s8+/development/root-using-odin-modified-firmware-t3693790” 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.

Can i root from android pie? and you can upload video on youtube to help root. Sorry my english very bad
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.
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?
you mean u hv your phone rooted on pie?
i can flash this?…i have android pie
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.
Does this work with the 9550 u?
CAN I USE THIS METHOD WITH LOCKED BOOOTLOADER SM-G955U1 TRACKFONE MODEL?
pls I hv this bootloader G955USQS5CR5 pls is that version 5
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.
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.
thanks for your reply …is it for only oreo or nougat?
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) ^^)
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.
Hi Brian! You’re welcome and thank you for such kind words. I am glad the tutorial was helpful.
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
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.
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?
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?
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?
Hello, it worked very fine, the only thing is that the face unlock function does not work, is there any fix for that issue?
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?
I’m with the same problem. How do i fix it?
do you know how to fix fail message on odin
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!
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).
Hi Miles. In that case, simply re-flash the stock firmware for T-Mobile and then re-root your phone using this process.
How do I re-flash a stock firmware (ex. T-Mobile) if I wanted to go back to stock rom??
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.
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
Are there any kernels that work with this?
Are there any roms that are compatible with this root?
I am sorry, but no.
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?
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.
Hy Dhananjay,
how to check my bootloader version?
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.
I have a G955USQU5CSA4 with this method work for me>

version android after flash?
Hi Lester. It will be BRB1 build based on Nougat.
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!
Hi AustinL. Have you tried re-doing the process from step 1?
One more thing, did you have a V4 or V5 bootloader?
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!
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?
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.
Hi Michael. What error does it show when you try to flash G955W firmware using Odin?
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
SetupConnection..
initialization..
Set PIT file..
DO NOT TURN OFF TARGET!!
Get PIT for mapping..
Firmware update start..
SingleDownload.
{Then the Window Pops up “Odin stopped working”}
I am using the stock firmware for my device and carrier. (downloaded from updato.com) 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.
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.
Hi Dhananjay,
Awesome! Thank you so much for your help. It worked perfectly!
Thx
S8+ snap của tôi đang là android 8.0 nếu giờ root thành công theo samfail thì sẽ về hệ android 7.0 à
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.
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.
Thx
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.
Hi again, Michael. I am glad it worked. I have updated the Odin article with the link to the patched version as well.
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.
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.
Would just like to say thank you. This worked perfectly. Took maybe 10 mins before I could use my phone again.
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)?
any method for s8 950u v5 ?
“FAIL! SHA256 is invalid”
g955u bl v5
i used the last version of odin
please help me
I have the same device and had the same issue. Use the PrinceComsy Version. Working like a Charm
i faced same problem but solved
use Odin “PrinceComsy”
Hi Bilal. Thanks for pointing that out. I have updated the instructions accordingly.
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.
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.
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.
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.
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.
Thanks
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.
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.
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!
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?
mine is G955USQS5CRI4, and i always get this error (using BL_V5):

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
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.
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

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 …
Hi, Shadokeeper. By any chance, is the ‘Auto Reboot’ option unchecked in the ‘Options’ tab of Odin tool? Please check and let me know.
my phone is “g955usqu5crk1” lasted update
will this way work for me?
can you record video doing this way 😀
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.
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
g955usqs2brb1 qualcomm snapdragon 835 will work? for tmobile
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.
Can I update from nougat 7.0 to oreo 8.0 after I rooted it?
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?
Hi, is there a way to make it work on G955W ( Canadian carriers ) ?
Yes, it should work. The CSC stays the same, only the system and bootloader partitions are modified.
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….
Hi !
Noob question but better than a dumb one. For my device it is currently running 8.0.0
Baseband is G955USQU5CRIB
Should this method work for me ?
I tried it and on the download page it didn’t reboot and it did give me the messages below while it was plugged in
Look forward to hearing from you !

Hi Red. Yes, this method will work for your model.
Did you use the correct files? I mean did you use BL_V4_PART_1.tar or BL_V5_PART_1.tar
Also, which Odin version did you use?
which one should we use for that baseband? V4 or V5?
device currently running 8.0.0 really work?
no need to downgrade?
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?
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.
But I thought this article said that this root method works for both Nougat and Oreo?
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!
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)?
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.
When I opened the Odin application a message about having the proper binary used. Then after clicking past the message, while on the first step with flashing the BL I came across a sha256 message so I then downloaded a patched version of Odin , same version, however I am stuck at the setupconnection message and it has not progressed at all.
Hi Brandon, please try using this one.
Ive tried this one as well as the other one, they both stop on the bootloader step with this error message, my baseband version is g955usqu5crk1if that matters
por error se me desconecto el movil, intente empezar el proceso pero ahora me marca este error

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
Hi Eric, at what step does this happen?
As for downgrading, you cannot downgrade from 8.0 to 7.0 due to bootloader restrictions.
It worked for me. I’m on an sm955u and I was able to downgrade from 8.0 to 7.0
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.
Alright I flashed everything worked great. It was for my gf. She can’t remember her Gmail password and now I am looking at frp. She changed her password 47 days ago. Any help on frp 8plus would be great guys…
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.
Thanks
Hi Alan, I am sorry but it only works for BL v4 and v5. v3 is not supported.
Thought so. Is there a way to upgrade the bootloader to 4 or 5?
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?
Thanks
Please make sure that re-partition is not ticked under the ‘Options’ in Odin program.
It is not checked, and i am still getting that same error
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?
