I have my FP2 for 1 week now. After having troubles using the GPS with OpenOS, I switched back to 1.5.1 to discover that GPS was still unusable, so I tried to downgrade to 1.4.2 but that was not a good idea as Google Service kept notifying me that it crashed. So ultimately, I decided to go back to OpenOS and wait until the GPS could be used. Everything went well. The phone was fully charged when I switched to “airplane mode” yesterday night. This morning, phone was working fine. But then after some time. I noticed the screen was black and pushing the on/off button did not do anything. Long pressing it did reboot the phone so I thought it simply crashed (!). But it did not reboot correctly and instead, went back to black. I did this a couple of times until the phone was flat dead
I tried to battery reset it, and I did get a short sign of life : battery charged with the animation showing few seconds, then only the LED was on. Again, after few minutes, everything is back to “no sign of life”. I’ve already tried the battery reset 3 or 4 times but can’t get my phone to boot.
I’ve tried with different cables and different chargers, so I thing this is not related to Charging the FP2 / cable problems .
I also don’t thing contacts are bad, as the phone can charge a bit before dying without being moved.
