UNOFFICIAL TIP :

@piero

if coming from an already installed “official” /e/OS and you want to upgrade to a15 “community” (without loosing data and locked bootloader)

• using → Settings → System updater → Local_update
• or using “recovery mode” and “adb sideload”

you will face a signature mismatch, simply choose “install anyway”
A clear guide to Upgrade your /e/OS to a new Android major version without loosing /data

Files for upgrading an existing /e/ system via local update or the /e/ recovery can be found here:

Here is my report of how I switched an FP3 from T-official to A15-community: https://community.e.foundation/t/feedback-for-v3-1-1/73830/46?u=urs_lesse As I remember, data was taken over and not reset – I did not need to change the (locked) bootloader, so no factory reset was triggered.

Is it possible to reverse to official whenever available later on ?

there is yet no feedback about reverting from “community” to “official” without data loss…
But switching back to “official” with a new install (and data loss) will be possible if the command
fastboot flashing get_unlock_ability is able to return 1.
(check the possibility to enable the “allow OEM unlock” option in “–> Settings → system → Developper Options”) NEVER DISABLE IT !
