New topic for increased visibility … to whom it may concern … from newest to oldest info …
Despite earlier contrary info, an OTA upgrade from Android 9 (Pie) to Android 10 (Q) is in the works.
According to forum user info, possibilities are still under review:
Studying different scenarii doesn’t mean it will amount to anything in the end, but it isn’t nothing either, there still might be hope.
It was clarified that the planned OTA upgrade on Fairphone 3/3+ (FP3) will be from Android 10 (Q) to Android 11 (R).
Support for /e/OS based on Android 9 (Pie) was dropped a while ago with /e/OS v1.0 on all /e/OS devices, and on Fairphone 3/3+ (FP3) no OTA upgrade from Android 9 (Pie) is coming.
The current Android version of /e/OS on a device can be seen in Settings - About phone - Android version.
Upgrading to Android 10 (Q) can be done manually via command line or via the Easy Installer and by default includes a data wipe, so user data on the phone will be deleted. Consider syncing to the cloud or backing up to a computer if necessary.
In the fringe case that the bootloader was left unlocked and should stay unlocked (with the accompanying security implications), there’s a chance that simply installing Android 10 (Q) manually via command line, making sure to not wipe any user data in the process (by not executing the
fastboot -w and
fastboot flashing lock commands), and just wiping the cache partition (by executing
fastboot erase cache) might result in a successful upgrade keeping user data and Apps (worked for me on Fairphones 2 and 3 after seeing a hint about it, but no guarantees).
Unlocking a locked bootloader for this now will not help, as this will force a factory reset (deleting user data) for security reasons, as will locking the bootloader.
When in doubt, the state of the bootloader can be seen in fastboot mode by keeping Vol - pressed while starting or rebooting the phone. It will display “DEVICE STATE - unlocked” or “DEVICE STATE - locked”. Just press the power button while the top of the screen displays “START” to reboot the phone into the OS again.
