Upgrade LineageOS on gts210wifi

Important: Please read through the instructions at least once completely before actually following them to avoid any problems because you missed something!

Warning: These instructions only apply to version upgrades. If you wish to downgrade to an earlier version of LineageOS, follow your device’s instructions for installing LineageOS the first time.

Manually upgrading LineageOS

Tip: In some cases, a newer LineageOS version may not install due to an outdated recovery. Follow your device’s installation guide to see how you can update your recovery image.

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.

Build a LineageOS install package.
- Optionally, download additional application packages such as Google Apps (use the arm architecture).
Make sure your computer has working adb. Setup instructions can be found here.
Run adb reboot sideload.
Run adb sideload /path/to/zip (inserting the path to your LineageOS package).
(Optionally): If you want to install any additional add-ons, adb sideload /path/to/zip those packages in sequence.

Note: If you previously had any Google Apps package installed on your device, you must install an updated package before the first boot of Android! If you did not have Google Apps installed, you must wipe the Data partition (or perform a factory reset) to install them.
(Optionally): Root the device by installing LineageOS’s AddonSU, use the arm package.
Once all installations are finished, run ‘adb reboot’.
