Upgrade android

This is my method to upgrade to major android version.

1. Download the distro file, in my case it is the latest zip file in https://download.lineage.microg.org/alioth/
2. Reboot in sideload mode

adb -d reboot sideload

3. Upgrade to the new version

adb -d sideload <your file>

It will take some time and there will be a message on the phone to tell me that it is completed.

4. reboot the phone and that’s it
