Basic requirements

  1. Make sure your computer has adb and fastboot. Setup instructions can be found here.
  2. Enable USB debugging on your device.

Unlocking the bootloader

  1. Enable OEM unlock in the Developer options under device Settings, if present.

  2. Connect the device to your PC via USB.
  3. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb reboot bootloader
    

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

    • With the device unplugged, plug in the device while holding the Side Button until Recovery is displayed. Now, click the Side Button to highlight “Advanced”, then long press the Side Button to select it. Then click the Side Button to select “Reboot Bootloader”, then long press the Side Button to select it.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  5. Now type the following command to unlock the bootloader:

    fastboot flashing unlock
    
  6. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
  7. Since the device resets completely, you will need to re-enable USB debugging to continue.

Installing a custom recovery using fastboot

  1. Download a custom recovery - you can download Lineage Recovery. Simply download the latest recovery file, named something like lineage-18.1-20211119-recovery-deadpool.img.

  2. Connect your device to your PC via USB.
  3. On the computer, open a command prompt (on Windows) or terminal (on Linux or macOS) window, and type:
    adb reboot bootloader
    

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

    • With the device unplugged, plug in the device while holding the Side Button until Recovery is displayed. Now, click the Side Button to highlight “Advanced”, then long press the Side Button to select it. Then click the Side Button to select “Reboot Bootloader”, then long press the Side Button to select it.
  4. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  5. Flash recovery onto your device:
    fastboot flash recovery <recovery_filename>.img
    
  6. Now reboot into recovery to verify the installation:
    • With the device unplugged, plug in the device while holding the Side Button until Recovery is displayed.

Installing LineageOS from recovery

  1. Download the LineageOS installation package that you would like to install or build the package yourself.
  2. If you are not in recovery, reboot into recovery:
    • With the device unplugged, plug in the device while holding the Side Button until Recovery is displayed.
  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:
    • On the device, select “Apply Update”, then “Apply from ADB” to begin sideload.
    • On the host machine, sideload the package using: adb sideload filename.zip.
  6. (Optionally): If you want to install any add-ons, repeat the sideload steps above for those packages in sequence.

  7. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
