Install LineageOS on
Nokia 6.1 Plus

DRG

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. Make sure your computer has adb and fastboot. Setup instructions can be found here.
  3. Enable USB debugging on your device.
  4. Make sure that your model is actually listed in the “Supported models” section here (exact match required!)
  5. Boot your device with the stock OS at least once and check every functionality.
  6. LineageOS is provided as-is with no warranty. While we attempt to verify everything works you are installing this at your own risk!

Pre-Install Notice

Unofficial bootloader unlocks for this device tend to leave the device in a strange state. This can cause a false data-corruption notice when updating LineageOS via the built-in Updater app.

To mitigate this issue, reflash the latest stock firmware for your model before starting.

Unlocking the bootloader

Installing Lineage Recovery using fastboot

  1. Build a LineageOS installation package. The recovery will be built as part of it!
  2. Connect your device to your PC via USB if it isn’t already.
  3. If your device isn’t already in fastboot mode, on the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb -d reboot bootloader
    

    You can also boot into fastboot mode via a key combination:

    • With the device powered off and plugged into USB port, hold Volume Down + Power.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    

    If you don’t get any output or an error:

    • on Windows: make sure the device appears in the device manager without a triangle. Try other drivers until the command above works!
    • on Linux or macOS: If you see no permissions fastboot try running fastboot as root. When the output is empty, check your USB cable (preferably use a USB Type-A 2.0 one or a USB hub) and port!
  5. Flash recovery onto your device:
    fastboot flash boot boot.img
    
  6. Now reboot into recovery to verify the installation. Do not reboot into the existing OS, since it will overwrite the recovery you just installed!
    • With the device powered off and plugged into USB port, hold Volume Up + Power. Keep holding both buttons until the “Android One” logo appears on the screen, then release Power but keep holding Volume Up.

Installing LineageOS from recovery

  1. Build a LineageOS installation package.
  2. If you are not in recovery, reboot into recovery:
    • With the device powered off and plugged into USB port, hold Volume Up + Power. Keep holding both buttons until the “Android One” logo appears on the screen, then release Power but keep holding Volume Up.
  3. Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one).
  4. Return to the main menu.
  5. Sideload the LineageOS .zip package but do not reboot before you read/followed the rest of the instructions!
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb -d sideload filename.zip.

Installing Add-Ons

  1. Click Apply Update, then Apply from ADB, then adb -d sideload filename.zip for all desired packages in sequence.
    When presented with a screen that says Signature verification failed, click Yes. It is expected as add-ons aren’t signed with LineageOS’s official key!

All set!

Once you have installed everything successfully, you can now reboot your device into the OS for the first time!

  • Click the back arrow in the top left of the screen, then “Reboot system now”.
