I just swappend the bottom module of my Fairphone 2 since it didn’t charge anymore and sat on the shelf for about a year. Now the phone turns on again, but immediately enters a boot loop: The while Fairphone logo appears for three seconds, then the phone immediately turns off again and starts over. This has been going for about 5 hours now.
Unfortunately, it seems like I can’t enter the recovery mode: When pressing the power + volume up button, the phone vibrates before the Fairphone logo appears, but nothing else happens, e.g. the screen goes black again after three seconds.
When pressing power + volume down, the Phone enters fastboot mode and my computer recognizes it using
fastboot devices. I successfully flashed TWRP 3.5.0 using
fastboot flash recovery, but that doesn’t change anything about the phones behaviour.
I have already removed the microSD and SIM card and the battery, the back cover and the bezel. Nothing helps.
I’ve read many threads in this forum on similar problems, but most of them were either solved by entering the recovery mode or by flashing TWRP. Unfortunately, that’s what I’ve already tried.
Any ideas on what I could try to further diagnose the problem? Thanks a lot in advance! The phone runs Fairphone Open, probably 18.10.0.
