Install LineageOS on PL2

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

Temporarily booting 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-17.1-20210122-recovery-PL2.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 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
   

   check

   Tip: If you see no permissions fastboot while on Linux or macOS, try running fastboot as root.
   check

   Tip: Some devices have buggy USB support while in bootloader mode, if you see fastboot hanging with no output when using commands such as fastboot getvar .. , fastboot boot ..., fastboot flash ... you may want to try a different USB port (preferably a USB Type-A 2.0 one) or a USB hub.
5. Temporarily flash a recovery on your device by typing:

   fastboot flash boot <recovery_filename>.img
   

   info_outline

   Note: Newer fastboot releases dropped legacy A/B support, so it might attempt to flash to boot__a / boot__b rather than boot_a / boot_b if you try to flash boot. In this case, you must manually specify which slot to flash to based on what slot fastboot failed to flash to. For example, if fastboot fails to flash to boot__a, you must flash to boot_a.
   check

   Tip: The file may not be named identically to what stands in this command, so adjust accordingly.
6. 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. Download the LineageOS installation package that you would like to install or build the package yourself.
   • Optionally, download additional application packages such as Google Apps (use the arm64 architecture).
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:
   • 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.
     check

     Tip: If the process succeeds the output will stop at 47% and report adb: failed to read command: Success.

6. (Optionally): If you want to install any additional add-ons, click Advanced, then Reboot to Recovery, then when your device reboots, click Apply Update, then Apply from ADB, then adb sideload filename.zip those packages in sequence.

   info_outline

   Note: Additional 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.

   Note: If you want Google Apps on your device, you must follow this step before booting into LineageOS for the first time!
7. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
