Upgrade LineageOS on mondrianwifi

Manually upgrading LineageOS

The updater app does not support upgrades from one version of LineageOS to another, and will block installation to any update for a different version. Upgrading manually requires similar steps to installing LineageOS for the first time.

  1. Build a LineageOS install package.

    • Optionally, download additional application packages such as Google Apps (use the arm architecture).
  2. If your device isn’t already booted into recovery, do so:
    • With the device powered off, hold Volume Up while booting.
  3. (Optional, but recommended): Tap the Backup button to create a backup.

  4. Sideload the LineageOS .zip package:
    • On the device, select “Advanced”, “ADB Sideload”, then swipe to begin sideload.
    • On the host machine, sideload the package using: adb sideload filename.zip
  5. (Optional): Install any additional packages using the same method.

  6. (Optional): Root the device by installing the LineageOS SU Addon (use the arm package) or using any other method you prefer.

  7. Once installation has finished, return to the main menu, tap Reboot, and then System.
