It started slowing down suddenly, I though maybe some app was causing trouble, so I decided to reboot. But it doesn’t boot anymore. Not even with power+vol up or down. If I try to charge, the led does not turn on neither. It doesn’t respond to any input. I don’t know what to do.
I was running Fairphone Open, and I updated to Android 9 some time ago and it was running smoothly.
I recently replaced the bottom module and it was working great also.
Any idea of what could I do? I had some photos and videos stored in the microSD, but do you think I could recover what was stored on the phone’s memory?
To Alex’s list, I’d just add:
Clean contacts (beginning with battery, SIM and SD card) with isopropyl (or high-percentage) alcohol. I recently resuscitated an original FP2 battery that wasn’t responding at all (well, hardly), by cleaning the battery contacts. Since then it’s worked so well I haven’t even put the more recent battery back in!
lsusb gave me this output: Bus 002 Device 005: ID 05c6:f006 Qualcomm, Inc.
So it seems it’s recognized. But I don’t know what to do next. It doesn’t appear as a device I can mount I my file explorer.
fastboot devices / adb devices showed an empty list
Now when I charge the FP2, the LED turns red, but after some time it turns off.
I will try cleaning the contacs as @OldRoutard suggested, and if that does’t work I will try with a new battery as soon as I can get one.
That’s exactly what I had with the old battery I’ve just put back in service.
Use a cotton bud. Moisten one end with alcohol, clean the contacts with it and dry them with the other end of the bud.
Right, so searching this ID tag on the forum leads me to the following topic:
On which I see:
Searched a little bit more, here’s what a qualcomm dev says about it:
The VID-05C6 PID-F006 is the low level code communicating with the PC for trickle charging power. This occurs when normal power is not provided and only the USB cable is connected. Applying AC power to the unit will cause the device to start booting.
Which would mean that your phone isn’t charging? I’m not sure I know how to interpret that. Perhaps your battery is dead and you should try a new one. Or hopefully perhaps, it’s only the contacts. Or it’s bricked (hopefully not).
If you have no recent Backup of your data, you might want to give Volker’s suggestion a try before proceed.
Does it boot into recovery automatically? If that’s the case, I for one would try to check if the system-Partition got corrupted by executing the “Mount /system” option from the recovery menu. If the Recovery can mount the partition without any error, than that partition is probably good. If the partition does not mount without an error, I probably would consider reinstalling the whole system. (But that’s just me, probably there are smarter ways.)
If the system-partition can be mounted, I would proceed to wipe the cache-partition. This should ensure that it does not contain any corrupted data. Then I would give it try and see if it still boots into Recovery.
