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. Visit Lenovo’s ZUI official unlocking website, where you’ll be asked to fill in some device and contact information.
  2. Follow the instructions and get your unlock file.

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

  4. Connect the device to your PC via USB.
  5. 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 powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
  6. Once the device is in fastboot mode, verify your PC finds it by typing:
    fastboot devices
    
  7. Now type the following command to unlock the bootloader:

    fastboot flash unlock sn.img
    

    Where sn.img is the bootloader unlock file you received in the email.

  8. Next, use your second unlock command

    fastboot oem unlock-go
    
  9. Wait for the bootloader unlocking process to complete. Once finished, you can check if bootloader is successfully unlocked by typing:
    fastboot getvar unlocked
    

    Verify that the response is unlocked: yes. In that case, you can now install third-party firmware.

  10. If the device doesn’t automatically reboot, reboot it. It should now be unlocked.
  11. 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-18.1-20210617-recovery-zippo.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 powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then release.
  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 powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then select recovery mode by pressing volume button, press the power button to reboot to recovery.

Installing LineageOS from recovery

  1. Download the LineageOS installation package that you would like to install or build the package yourself.
    • Optionally, download an application package add-on such as Google Apps (use the arm64 architecture).
  2. If you are not in recovery, reboot into recovery:
    • With the device powered off, hold Volume Down + Power. Keep holding both buttons until the word “FASTBOOT” appears on the screen, then select recovery mode by pressing volume button, press the power button to reboot to recovery.
  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”.
