I have an FP3 with valuable data here in front of me which is stuck at the splash screen of iodé (because of the personal data I don’t want to factory-reset it). When it stays there for some time it even gets warm, but it does not boot up. It was just restarted at some time and without any sign of a problem before it got stuck there.
What I have tried so far:
remove SIM-cards and µSD-Card → doesn’t help
insert a different battery
start in safe mode (after FP-writing disappears vol- → doesn’t work (stays stuck there, too)
boot into fastboot → works, but doesn’t help: tried to switch slots, but neither of them boots beyond splash screen. what else could I do there?
boot into recovery → works, but I can’t push/pull anything as I always get
error: device unauthorized.
This adb server’s $ADB_VENDOR_KEYS is not set
Try ‘adb kill-server’ if that seems wrong.
Otherwise check for a confirmation dialog on your device.
(killing adb server of course didn’t help). I guess debug mode isn’t enabled?
sideload iode-3.4-20221215-FP3.zip → works, but doesn’t start either. (I hope this step didn’t delete the data?) → still stuck
I have run out of ideas and my friends is becoming really sad
In this case you could try to simply boot TWRP with fastboot and see whether it asks for the decryption password of the user data, which would be the unlock password/PIN for the Android lock screen (I don’t know whether the bottom of this page still helps with unlock patterns, or if TWRP is able to prompt a pattern UI).
If TWRP asks for the password (should be the case up to Android 11 *), and if the correct password can be provided, TWRP should be able to decrypt the data partition, and you should be able to copy the whole Internal Storage to a computer via USB.
(* At least in /e/OS based on Android 12 the encryption changed to a type TWRP can’t decrypt currently.)
Happy New Year!
Unfortunately, this didn’t do the trick either.
The place of the phone which is becoming warm is (when I have the opened phone lying in front of me) seems to be the place left of the battery above the µSD-slot. Which part is this, do you know? Maybe it is not a software-problem but a hardware one?
Last message: the FP is running again. but not with iodé and I could not save the data.
I finally flashed the original A11 and because it still did not boot (unsurprisingly) did a factory reset
Obviously not a hardware but a software problem.
