I finished everything and there didn’t seem to be any issues, except that when I rebooted to the new OS (saw the logo and everything) the touchscreen wasn’t working (it was working before on the default phone OS). I restarted it again (and also tried to take the battery in and out), but no go. Now, after another restart the display is completely black. (I see a light indication when plugging it in to charge, and also hear an appropriate sound effect).
Since I locked the bootloader (as the instructions mention) I no longer have access with adb/fastboot from my computer. I can’t see anything and the touchscreen probably isn’t working.
I can’t think of anything else to do, so any help or input would be greatly appreciated.
I did that, and felt/heard the phone vibrate (just like when I reboot it by just pressing the power button).
It’s connected to my computer, adb devices shows nothing, however when I do fastboot -w I get:
Erasing 'userdata' FAILED (remote: 'device is locked. Cannot erase')
Just tried that.
Doing fastboot flashing unlock, I get: OKAY [ 0.081s] Finished. Total time: 0.081s
Then if I reboot the device, I still get a black screen. If I go into fastboot mode again (with power + volume down) and do fastboot -w, I still get: Erasing 'userdata' FAILED (remote: 'device is locked. Cannot erase') fastboot: error: Command failed
Yes, that’s true. I will admit my gut tells me this is a hardware issue too.
I’m trying these steps now to install the default FP3 OS, but… if it doesn’t work - am I out of luck? I’m assuming if I contact Fairphone support they’ll tell me I voided the warranty by flashing a new OS, won’t they?
Update: I installed the Fairphone OS and still no go. Now I’m not even sure whether the phone is turned on/off (I don’t get any indication when plugging it in/out of the power supply and the charging light is always off). I tried turning it off/on a few times and no luck.
Going to try reconnecting the display module as you suggested. Will update shortly.
One last try in software: Is the screen staying black if you boot (not install, only boot) the TWRP recovery? https://twrp.me/fairphone/fairphone3.html … download the IMG file to your computer, then with the phone in Fastboot Mode and connected to the computer fastboot boot filename (substitute filename with the actual filename of the IMG file) and give it about a minute to boot.
Else … If you happen to have Fairphone Angels (volunteer helpers from the Fairphone community) with a Fairphone 3 in your vicinity, you could ask whether it would be possible to test a different display module with your phone to make sure you really (only) have a faulty display.
Else … I guess it would be time to contact Fairphone support to see what they can come up with.
If there were no errors while reinstalling the stock OS, the phone is now in a supported state, and Fairphone couldn’t possibly argue that rebooting the phone or installing /e/ (official partnership and all) could kill hardware just like that. Just my opinion, of course.
