I did the last /e/os update on my phone and after the reboot I saw the home screen for a few second and then nothing, no more display. I saw the screen for half a second a few hours later but since then full black.
All the solution that i have found need to have OEM unlock and USB debugging but I can’t access it since i can’t see the screen… (i tryed adb but it’s “unauthorized” device)
Even if i reboot the phone (by guessing where the button is) i never see any display but i feel the haptics and can turn on the light.
Any idea to fix it or recovering the data at least?
In this situation we expect to be able to reach fastboot.
With the device powered off - hold Volume Down + Power
It is unlikely you can use any fastboot command to recover data.
However you can attempt a rollback to the previous version on an A/B slot device. I suggest you search this if unfamiliar (it will not always be successful with a Custom ROM). Perhaps also a read through of the install page Install /e/OS on a Google Pixel 5a - “barbet”.
Check if you have fastboot communication
fastboot devices
Find the current slot in use (assuming this slot contains the failed update)
fastboot getvar current-slot
Expect a response like
current-slot: b
Finished. Total time: 0.000s
Now attempt to change slot (be aware of the exact slot name in case it might be _b
fastboot --set-active=<the slot you want>
From the previous example the command would be
fastboot --set-active=a
An alternative is to try
fastboot --set-active=other
Now reboot to system to see whether the old /e/ version is available.
I managed to do the roll back to version “a” previously “b”. Unfortunatly it didn’t fix the problem.
It make me think it’s more a screen problem more than a software issue since i don’t have any display in fastboot either. The fact that it happen right after the update was maybe just a coincidence?
I guess the only solution left would be changing the screen (if possible) since i can’t cast the screen on a other screen on this Pixel model apparently.
