Upgrade LineageOS on tissot

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. Download the LineageOS install package that you’d like to install or build the package yourself.

    • Optionally, download additional application packages such as Google Apps (use the arm64 architecture).
  2. Make sure your computer has working adb. Setup instructions can be found here.
  3. Enable USB debugging on your device. Additionally, open Settings, then “System”, then “Developer Options”, and then either check “Rooted Debugging” (LineageOS 17.1 or above) or select “Root Access Options”, then “ADB Only”.
  4. Run adb reboot sideload.
  5. Run adb sideload /path/to/zip (inserting the path to your LineageOS package).

  6. (Optionally): If you want to install any additional add-ons, run adb reboot sideload once more, then adb sideload /path/to/zip 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”.
