Install LineageOS on nairo

Unlocking the bootloader / Installing a custom recovery

There are no recovery installation instructions for this discontinued device.

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:
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: Normally, adb will report Total xfer: 1.00x, but in some cases, even if the process succeeds the output will stop at 47% and report adb: failed to read command: Success. In some cases it will report adb: failed to read command: No error or adb: failed to read command: Undefined error: 0 which is also fine.

6. (Optionally): If you want to install any add-ons, repeat the sideload steps above for those packages in sequence.

   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.

   Note: If you want the Google Apps add-on on your device, you must follow this step before booting into LineageOS for the first time!
7. (Optionally): Root your device by installing LineageOS’ AddonSU, (use the `` package) or by using any other method you prefer.
8. Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
