bart877ie, I tried your steps but I don't get the prompt you mention at (6) - is your phone rooted?

No, it is stock. No software alterations were made. GPS is still working without issues. It is almost impossible to get lock/fix inside the building, but outside it works very well. I was driving and cycling and everything is as it should be.

Is your device still unable to fix/lock to GPS? I have done factory reset today and GPS was unable to get fix. But when I recreated those steps it started to work.

Hi everyone, just received my Crystal 4GB and to my sad surprise the GSM module (or antenna) is not working correctly, so the can't log to network. It logs occasionally for couple seconds to drop the connection again. One way or another, I didn't manage to make any single call. All other function seem to be working well. I have updated phone to the latest firmware and checked several sim cards that were working well on other phones placed next to Crystal. Any suggestion on what to do would be appreciated.

I'm having this error too, but I'm pretty much sure it's because I enabled root in Developer optio ...

I have disabled root but I still have the same error, I tried to update using recovery but this is what I receive, I absolutely cannot do a factory reset and reinstall everything on two phones, this is madness.

It seems your boot partition has been modified.
There's also "OEM unlocking" switch in Developer options which unlocks the bootloader.
Did you maybe enabled that option? It might be the reason for the error message you receive.

I have not experience all those issue that I saw here. Dialer is ok, camera is ok for my needs. 4G is present when signal is at minim. GPS loose the signal from time to time. The problem is with very low signal with wi-fi 2-3 m close to the router. And of course the battery sucks. Another issue, when inserted audio jack, the screen has white cloud in that area. I'll try tomorow to fix GPS with engineer mode.
