Upgrade LineageOS on
Nokia 8

Basic requirements

1. Read through the instructions at least once before actually following them, so as to avoid any problems due to any missed steps!
2. You actually want to upgrade your device to the newest version - if you wish to downgrade to an earlier version of LineageOS, follow your device’s instructions for installing LineageOS the first time.

Manually upgrading LineageOS

The updater app does not support upgrades from one version of LineageOS to another, and will block installation to any update for a different version. Upgrading manually requires similar steps to installing LineageOS for the first time.

1. Download the LineageOS install package that you’d like to install or build the package yourself.
2. If you are currently using (or now want to use) an application package add-on such as Google Apps, you have the following options:
   • keep using them: Download the appropriate version now (use the arm64 architecture)
   • remove them: You can only do so by performing a factory reset, which will also remove all your data.
   • start using them: You can only do so by performing a factory reset, which will also remove all your data. Download the appropriate version now (use the arm64 architecture)
3. Make sure your computer has working adb. Setup instructions can be found here.
4. Enable USB debugging on your device.
5. Run this command to reboot into bootloader mode:

    adb -d reboot bootloader
   

   or by performing the following:

   • With the device powered off and plugged into USB port, hold Volume Down.
6. Flash the super_empty partition to retrofit dynamic partitions to your device (inserting the path to your super_empty.img file):

    fastboot wipe-super --slot=all /path/to/super_empty.img
   

   info_outline

   Note: This process only needs to be performed if you are upgrading from LineageOS versions older than 22.2 that still utilize the legacy partition layout.
   info_outline

   Note: If you get the following error: fastboot: usage: unknown command wipe-super, make sure ADB and fastboot are updated to the latest version. You need fastboot version 28.0.2 or greater.
7. Update to the latest Lineage Recovery image. Simply download the latest recovery file, named boot.img. Follow your device’s installation guide to upgrade your recovery image.
8. While you are in bootloader mode, run this command to enter recovery mode:

    fastboot reboot recovery
   

   Or by performing the following:

   • With the device powered off and plugged into a USB port, hold Volume Up. The “Powered by Android” logo will appear on the screen, keep holding it until you reach recovery mode.
9. Once you are in LineageOS recovery, select “Apply Update”, then “Apply from ADB” to put the device into sideload mode.
10. Run (inserting the path to your LineageOS package):

     adb -d sideload /path/to/zip
    

    check

    Tip: Normally, adb reports Total xfer: 1.00x, but in some cases, even if the process succeeds, the output may stop at 47% and show adb: failed to read command: Success. In other instances, it might display adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.
11. (Optionally): If you want to install any add-ons, click Advanced, then Reboot to Recovery, then when your device reboots, click Apply Update, then Apply from ADB, then run for each of those packages in sequence:

     adb -d sideload /path/to/zip
    

    info_outline

    Note: If you previously had any Google Apps add-on package installed on your device, you must install an updated package before the first boot of Android! If you did not have Google Apps installed, you must wipe the Data partition (or perform a factory reset) to install them.
    info_outline

    Note: Add-ons aren’t signed with LineageOS’s official key, and therefore when they are sideloaded, Lineage Recovery will present a screen that says Signature verification failed, this is expected, please click Continue.
12. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
