Upgrade LineageOS on gta4xlBack to the overview
If the vendor provided multiple updates for that version, e.g. security updates, make sure you are on the latest!

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.
- Download the LineageOS install package that you’d like to install or build the package yourself.
Make sure your computer has working
adb. Setup instructions can be found here.
adb reboot sideload.Important: The device may reboot to a blank black screen, fear not, this is a known bug on some recoveries, proceed with the instructions.
adb sideload /path/to/zip(inserting the path to your LineageOS package).
- (Optionally): If you want to install any add-ons, click
Apply Update, then
Apply from ADB, then
adb sideload /path/to/zipthose packages in sequence.Note: If you previously had any Google Apps add-on 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.
- Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.
