I got a second hand FP2 which has a reboot problem. If it is switched on it starts booting. It comes to the stage where “Change is in your hands” is shown for some seconds, but then it reboots again.
I was able to install latest Fairphone Open using fastboot. So it should not be a problem related to any app. I can boot into TWRP without problems. But if I try to boot into the system this leads to the reboot cycle again.
So I believe this is not a software or installation problem, but somewhere hardware related. Any hints how I can identify the hardware component which is causing the reboot?
BTW: I’ve swapped the battery with another FP2 without a change in the behaviour. So the battery does not seem to be the problem.
@Johannes speaking of bottom modules: I opened a support ticket asking for a replacement module via the form on fairphone.com a couple of days ago (so no direct email), but I didn’t receive a confirmation email. Is this normal?
@zone42 sorry if this doesn’t fit here, but I don’t want to open yet another topic regarding bottom modules, and since it is a simple yes/no question, I think it won’t distract too much from the topic here
Any system modifications (root / openGapps / …)? Is the google app still enabled?
Solutions depend on your setup: e.g. if you did have openGapps installed, flash it again from recovery before booting (but after the update).
Some issues are caused by incompatibilities between user data and the upgrade process (e.g. the openGAPPs case). The nuclear option (i.e. destroy the data) to solve those is, when in fastboot mode (see manual upgrade instructions): fastboot format userdata
I just did a fastboot format userdata, followed by flashing of FP2-gms-17.11.2-manual.zip through fastboot. I still seem to be stuck on the boot screen…
Hard reset I already did… so I’m clueless as to why I’m having problems.
openGapps I never installed since I was using the non-open FP2 OS. More than a year ago I attempted to root the FP2. SuperSU would install, but I never managed to obtain root. Is this something that might cause my problems? Even after format userdata, factory reset and wipe of everything except microSD?
I’ll post the contents on the root folder in a bit.
