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

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).
If your device isn’t already booted into recovery, do so:
- With the device powered off, hold Home + Volume Up + Power.
(Optional, but recommended): Tap the Backup button to create a backup.
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
(Optional): Install any additional packages using the same method.

Note: If you previously had any Google Apps package installed on your device, you must follow this step before the first boot into Android! If you did not have Google Apps installed, you must wipe the Data partition (or perform a factory reset) to install them now.
(Optional): Root the device by installing the LineageOS SU Addon (use the arm package) or using any other method you prefer.
Once installation has finished, return to the main menu, tap Reboot, and then System.
