Hi. I was charging my FP2 (unmodified Fairphone OS, updated to 1.6.2) today when it suddenly rebooted (which is not uncommon after the update to 1.6.2). The problem this time is that after that, it went black and got stuck in a loop where the screen and charging light are black, and the phone’s vibrator just buzzes in short bursts about every 1,5 second. This has never happened before.
Whatever I try, it just does the same buzzing loop. If I take the USB cable and battery out it stops. If I put the battery back in, nothing happens until I press the power button, and the buzzing loop starts again. Same thing if I insert the USB cable, same thing if I have the battery in or not.
I’ve removed SD card and SIM cards, and no change.
I’ve tried holding the power button for 20 seconds, nothing. Tried holding the volume up when pressing power button, nothing. Same with volume down.
Tried taking the battery out for an hour, no change. Tried removing and reattaching the screen, no change.
Tried connecting the USB cable to my PC and checking ‘adb devices’ and ‘fastboot devices’, but it doesn’t get listed, since it doesn’t even seem to get that far in the boot process.
Any more ideas, or will it need to be replaced? I might also mention that this was one of the FP2:s that quite often hung with the black screen and had to be rebooted by holding the power button down.
Hi Anders, I’m having sames symptoms & issues. For me, it occurs after 1.7 release: after ~7h of normal usage the battery charge drops off suddenly to 2% and then black screen appears. THE BATTERY WAS WORKING PERFECTLY BEFORE. I plug the phone on power supply -> the loading animation remains even if I unplug the device ! Now I don’t have anymore the loading animation but the device is permanently rebooting…I have tried all what you have done: I’m stuck.
I’m not even getting the loading animation, only a black screen and the
vibrator buzzing. Do you have that too? In other case, I don’t think
this is the same error.
This morning situation is getting worse: no animation - only black screen, vibrator buzzing with FairPhone logo 'powered by androïd", loading… and black screen again with red led flashing…maybe not the same problem than yours but very similar. Do you plan to send it back for recovery ? Do you get answer from official support ? I have posted a ticket …waiting for reply
I did it but without success…I wipped all data and came back to factory settings …still rebooting in loop. I also try to update manually using SDCARD with 1.7 zip file - still the issue. I began return procedure.
