Manually Installing OTA Updates on Nokia 7.1

Software updates for the Nokia 7.1, like any other Android phone, are rolled out over-the-air. And due to the nature of these OTA updates, they are rolled out in phases, which is influenced by factors like regions, carriers, etc.

And so, when the original equipment manufacturer (HMD in this case) releases a software update for your phone, it could take some time before it’s actually available for your specific unit. This time period could range from a few days to weeks.

But you can skip the waiting, and manually upgrade your phone to the latest software version right away. This could be done by download and manually installing (sideloading) the OTA update ZIP file on your Nokia 7.1 using the in-built stock recovery. Manually updating your phone using this method doesn’t require you to unlock the bootloader or do anything else that could affect your phone’s integrity.

Through this page/repository, you can download all Nokia 7.1 OTA update packages, including that of the latest December 2020 security update from here, and further follow the provided instructions to manually install it.

Prerequisites

  • To sideload an OTA, you will need a Windows, macOS, or Linux PC.
  • Manually installing OTA updates on your phone will not erase any data. However, we still strongly suggest taking a full backup of all your important data to safeguard it. You can go through this detailed post for instructions on how to do it.
  • Charge your Nokia 7.1 to a sufficient battery level. This should help prevent any sudden shutdowns during the update process.

Nokia 7.1 OTA Updates Download Links

Below, you will find direct links to download the OTA packages of the all software updates for the Nokia 7.1 (codename: CTL_sprout) released till now. These packages were captured directly from the official Google OTA servers. The links are listed in increasing order, so the latest one will be at the very bottom.

Note: You could also help us by capturing the OTA URL of an update when it arrives on your phone and sharing it with us. This would allow us to keep this page updated at all times with the new updates as they are released.

About OTA Updates

OTA updates are available in the following two forms:

  • Incremental OTA updates: These can only be installed over a specific software version and are small in size. Most OTA packages of monthly security updates are incremental in nature. For example, the V4.15M February 2021 security update can only be installed on your Nokia 7.1 only if it has the V4.15L January 2021 update installed.
  • Full OTA updates: These are much bigger in size and can be installed over any previous software version. Maintainance releases and major Android version updates are full OTAs. For example, the latest Android 10 update can be installed on your phone irrespective of the previous Android Pie software installed.

So, if you’re installing a monthly security update over a previous one, take note of the current software version installed on your Nokia 7.1 first. You can get this info by going to ‘Settings‘ > ‘About phone‘ on your phone. Then download the OTA package of the next update accordingly.

If you’re going to install a full OTA package like Android 10, then the installed software version doesn’t need to be accounted for.

How to Manually Install OTA Updates on Nokia 7.1?

To manually install software updates on your Nokia 7.1, you will need to sideload the OTA zip package via the stock recovery. The process is extremely simple. You just have to download the OTA update file, boot your phone into stock recovery mode, and enter ADB sideload command on your PC to sideload the OTA.

Follow the instructions below.

Step 1: Install ADB on your PC

The first step of the process is to install and setup ADB on your Windows, macOS, or Linux PC. ADB is basically a command-line tool used for debugging and other purposes like sideloading updates in this case.

So, start by downloading the Android platform-tools package according to your PC’s operating system from below.

Once you have downloaded the package on your PC, all you have to do is extract the ZIP file using an archive tool like 7-Zip. The extracted “platform-tools” folder should contain the required ADB binary and other related files.

To make it easier to access, move the ‘platform-tools‘ folder to the root of the C:\ drive, if you’re using a Windows PC, or to the ‘Documents’ directory if you’re using a Linux or Mac PC.

Step 2: Download the OTA Package and move it inside the ‘platform-tools’ folder

Now, download the OTA zip file of the software update that you want to install. Once downloaded, move the file to inside the “platform-tools” folder you extracted during the last step. This will allow the command-line to identify the OTA package while sideloading.

Move the Nokia 7.1 OTA Package inside the 'platform-tools' Folder

Step 3: Launch the command-line on the computer

With ADB and other platform-tools in place, you now need to launch the command-line window within the same folder. To do this:

  • On Windows: Open the platform-tools folder, then hold the SHIFT key on your PC’s keyboard and right-click on any empty space inside the folder. Then select ‘Open PowerShell window here’ or ‘Open command window here’ (Depending on Windows OS version).
    Launch PowerShell on Windows PC
  • On macOS/Linux: Launch the Terminal and use the ‘cd’ command to change its directory to the platform-tools folder. For example, if you have moved the ‘platform-tools’ folder inside the ‘Documents’ directory, then the command should look like the following:
    cd Documents/platform-tools

    Launch Terminal on macOS/Linux PC

Once you have done this, your PC should be completely ready to sideload the OTA package.

Command-line usage: When entering the commands provided below, make sure to precede them with a dot and backward slash “.\” in Windows PowerShell or with a dot and forward slash “./” in macOS/Linux Terminal.

Step 4: Verify ADB Connection between the phone and PC

Enable USB debugging on your Nokia 7.1 now and connect it to your PC via a USB cable. Next, enter the following command in the PowerShell/Terminal on your PC to ensure that your PC can communicate with your phone over the ADB interface:

adb devices

Select ‘Allow‘ if you see a prompt on your phone’s screen to allow USB debugging.

Allow USB Debugging on Nokia 7.1

The command should return a unique device ID. In case it doesn’t, it means that the proper ADB drivers are not installed, in which case, you can download and install them from here.

Step 5: Boot your Nokia 7.1 into the Stock Recovery mode

Now, to install the OTA update, you have to boot your phone into the stock recovery mode. To do this, simply issue the following command:

adb reboot recovery

Your Nokia 7.1 should now automatically boot into the stock recovery mode and you should the ‘No Command‘ screen with an Android bot as shown in the figure below. To enter the stock recovery, simply hold the Power key and tap the Volume Up key once.

Nokia 7.1 Stock Recovery 'No Command' Screen

Step 6: Enable ADB Sideloading in Stock Recovery

For the stock recovery to accept the OTA installation, you must enable ADB sideloading. To do this, use the Volume keys to move the selector to ‘Apply update from ADB‘ and press the Power key of your phone to confirm the selection.

Select 'Apply update from ADB' in Nokia 7.1 Stock Recovery

Step 7: Sideload the OTA Update on your Nokia 7.1

Now, enter the following ADB command in PowerShell/Terminal to start sideloading and install the OTA update on your Nokia 7.1:

adb sideload ota-filename.zip

Here, “ota-filename.zip” needs to be replaced with the actual filename of the OTA package you’re sideloading. For instance, if you have downloaded the OTA file of the latest February 2021 security update, then the command should look like the following:

adb sideload 985603d185fdd3febce872fa0ab2e3d6c57562f9.zip

Enter ADB Sideload Command to Install OTA Update on Nokua 7.1

As soon as you enter the command, the stock recovery will begin the OTA installation. The progress for the same should be shown at the bottom of your phone’s screen. The process could take from a couple of seconds to a few minutes to complete, depending upon the size of the file. So, leave the USB connection undisturbed.

Step 8: Reboot your Phone into the Updated OS

Once the update has been installed, use the Volume keys to move the selector to ‘Reboot system now‘ and confirm it by pressing the Power key.

Select 'Reboot system now' in Nokia 7.1 Stock Recovery

That’s it! You have just successfully updated your Nokia 7.1 to the latest software version by sideloading the OTA package. You could repeat the same process to manually upgrade your phone every time a new update is released. We will give it our best to keep the download links up-to-date.

If you face any problems while following the instructions in this guide or have any questions regarding the whole manually updating concept, please feel free to ask us. Please don’t forget to share the exact software version number currently installed on your phone while seeking help.

Enjoy your updated phone now!

    1. Thanks a lot, Fred! I am sure other readers would find it really useful. I have added the OTA link for the February 2021 update in the post.

  1. Many, many thanks! You made my day!
    My 7.1 was stuck on 4.15G and did not find any updates on its own, the support could not help me.
    After installing 4.15H via sideload, the 7.1 was able to find recent updates on its own.
    Thank you!

    1. You’re welcome! Glad the instructions helped you update your Nokia 7.1 manually.

  2. Hi,

    I tried the 415F update but alas my phone needs a full firmware download as it is stuck now in Qualcomm HS-USB Loader.

    Only real solution would be a full major firmware release as the bootloader is not unlocked and it won’t let me downgrade to any previous version.

    Any idea if such file will be available at all?
    I tried all the nb0 files i could find on the net for free. non of them are able to flash.

    please help
    thanks

    1. Hi again. If that’s the case and you don’t seem to have any other options, I would suggest contacting Hikari Calyx through his website.

      He is extremely experienced with bootloader unlocking, downgrading, and unbricking Nokia Android phones.

  3. Hi, please provide CTL-415E or newer full update as my phone got soft bricked during update and it I cannot downgrade to any of the previous firmwares as it says timestamp is older.

    I am stuck on android logo screen and no wipe of data helps. tried OST LA flash – not good. QLIF flash not good. ADB sideload older firmware – not good.

    only thing left is newer firmware or the same version

    FULL-OTA or FULL nb0 file is required of at least version 4.15E
    model: TA-1095

    thanks a lot
    if it is not out yet – any idea when?

    1. Hi Toma. I have added the link to the 4.15E (June update) OTA file. It’s an incremental OTA. Full OTAs are only made available for maintenance releases and major Android version upgrades.

      Do let me know how it goes.

    2. Hi Toma. OTA file of the July update (V4.15F) is now available. Have you tried it to see if it works?

    3. Unfortunately my phone is stuck on Qualcomm QFLoader Black Screen…

      i need a full firmware nb0 file which is higher than 4.15E as anything previous gives me error
      0xc3be
      ERROR: function: main: 303 Uploading Image Using Sahara Protocol Failed

      using OST 6.2.8 Tool

      please help!

    4. That doesn’t look good. Is the bootloader unlocked? Have you tried using a different cable and a USB 2.0 port?

      I tried searching for nb0, but could only find for v3.45A here.

    5. CLT-415F-0-00WW-B03 please anyonw peovide me this file i get stock hang on logo of android one from one week on nokia 7.1

    6. It’s there among the download links (the July 2020 security patch is labeled 4.15F). OTA file for the August 2020 update has been added as well.

    1. hi,
      actually my mobile is stuck on android one logo. it is last updated to April security update.
      so i tried installing may update through ADB but it reached 47% and after some time ( around 20-30mins) it is showing
      “adb: failed to read command: no error”

      and in mobile it is just showing “installing update. . .”
      any solution for this?

    2. Hi Bhavish. Simply hold the Power button for 10-15 seconds. This will force-turn off the phone. Then boot it again into the stock recovery and try sideloading again. This time, try a different USB port of your PC, preferably USB 2.0.

    3. Hi, as you said i used USB 2.0 port. and its been 1 hour and it is still stuck at 47% on cmd prompt and “installing update. . .” on mobile. not going beyond that. Is it usual to take this long to install software?

    4. Hi again. Not, not that long at all. Could you please share the exact information you see on the top of the recovery screen?

    5. hi, I even tried updating may patch using “update from SDcard” option from recovery mode. but here also same issue. It completed package verification and then simply stuck on “Installing update. . .” ( its been 45mins still stuck at installing update)

    6. That’s really odd. Maybe it’s something with the update package itself. Your Nokia 7.1 is currently on the V4.08G April 2020 security patch, right?

    7. Yes, it is currently on April security patch. and it is stuck on android one screen. (It worked fine for almost 2 weeks after updating to April patch, then it got stuck suddenly)

    8. Okay. So, there are two things you could try.

      1) Switching to the phone’s inactive slot (Where the previous software version was installed, before the April update)
      2) Performing a factory reset via the stock recovery.

      Of course, the factory reset is the secondary option.

    9. Hi sir,
      I have tried to factor reset. But it is not moving beyond “wiping data/factor reset” screen.
      I have sent you a message my mobile recovery screen image in Facebook. So, please try to help me.

      And thank you so much for replying to my comments.

    10. Hi again, as I also messaged you over at Facebook, there are only two things I can suggest given the situation.

      1) Try sideloading the V4.15C full OTA via ADB
      2) If it fails, I wouldn’t suggest meddling any further. Simply take the phone to your nearest Nokia service center and ask them this happened after the latest update installed.

      I am confident they will fix it for you.

  4. Hi,
    My Nokia 7.1 is stuck on Androidone screen.
    I tried factory reset, but didnt work and it was stuck on wiping data for more than 4 hours.
    I am trying to update through adb, in expectation that it would resolve some problem, CTL-408G-0-00WW-B01-update.zip but adb serving not going beyound 47%.
    any resolution for my problem.

    1. Hi Satish. How did you phone get stuck on the Android One screen? After performing an update or randomly by itself?

      Also, could you please share the exact info you see on the top-left of the stock recovery screen (in yellow color)?

  5. Hello, my installation is successful but then i get messages like
    “e: can’t open /logfs”
    and after the reboot I have only try again or factory reset as options.
    Can you please help me? I can’t find anything online.
    Thanks

    1. Hi Fani. May I know which update was installed on your phone before you tried this?

      Also, which file did you exactly download and install? Please share this info with me.

  6. Hi Dhananjay! Have the same problem here and cant install the OTA update (getting the message: Update package is older than the current build, expected the build newer than timestamp 1582814602 but package has timestamp 1573729404 and downgraded not allowed). The firmware build number is 00WW_4_08F. Would you please help? Originally I got an error as described here. I managed to wipe the phone (dunno why I did it though) but when it comes down to installing OTA update I get the message above and can’t do anything else.

    1. UPD: Just realized the packages won’t work for me as I have 4_08F… any ideas when F > G will be available?

    2. Yes, you can’t sideload an update that’s already installed on the phone.

      I have just added the link for the V4.08G May 2020 update. Please take a look at the downloads section above.

    3. Hi Dhananjay,

      many thanks for the support on android dev topics.
      Please note that “b032610a4b09631b9bd12d04d18e04eccec177a6.zip” after renaming and ADB update, gives error-> “Package is for source build 00WW_4_08F but expected 00W_4_08G”. Could you please provide the correct 00W_4_08G file?

      Greetings

      Petros

    4. Hi Petros. Thanks for the kind words, and you’re most welcome.

      Could you please go to ‘Settings’ > ‘About phone’ on your phone and let me know the exact info it shows under the build number section?

    5. Hi Dhananjay,

      Unfortunately the phone is now stuck in Android Recovery.
      Indication “Cannot load Android system” and “enablefilecrypto_failed” at the bottom of the screen. The only info I can get is-> 10/QKQ1.190828.002/00W_4_08F from the same screen. As I have this problem, I try with ADB update to flash ROM/patch to avoid factory reset. I should keep the data.
      I hope the above info helped.

      Kind Regards,

      Petros

    6. Some additional info. Following your instruction and getting to the full Android Recovery menu (Apply update from ADB, SD Card ), I just realize that different version info is presented. That is 10/QKQ1.190828.002/00W_4_08G. While in the block screen with options Try Again, Factory Reset 10/QKQ1.190828.002/00W_4_08F is presented.

      Is it possible that difference is leading to the problem?
      Thank you in advance

      Kind Regards,

      Petros

    7. Hi Petros. Can you share a photo of the info shown on the top of the stock recovery screen? The info will be in yellow color, at the top-left of the recovery screen.

    8. Hi Nicke. The OTA file for the May update is not available yet. As soon as it is, I will update the post with the download link.

    1. Hi Ajay. Downgrading is only possible if the bootloader of your phone is unlocked.

    1. Hi Ajay. When you downloaded the OTA package (29ad191f90eedc643ed008dc06c81ed3c5b5565a.zip), did it show .zip at the end or not?

    2. update package is older than the current build,expected a build newer than timestamp 1582814602 but package has timestamp 1573729404 and downgrade not allowed………..ab yeh show ho rha h sir …ab ky kre..plzz help sir

    3. Hi Ajay. Which firmware build number do you currently have installed on your Nokia 7.1? Please go to ‘Settings’ > ‘About phone’, check that, and let me know.

    4. Ajay. First off, keep holding the power key for 6-10 seconds to power off your phone. As soon as the screen goes black, hold the Volume Up and Power key together.

      You should then see the ‘No Command’ screen. On that screen, hold the Power button and tap the Volume Up key once.

      In doing so, you will boot your Nokia 7.1 into the stock recovery mode. On the top left of the screen, you should see some info regarding the phone in yellow-colored text.

      Please share that exact info with me. If you want, you can contact me via our Facebook page. I will try and help you as quick as possible.
