[Q] Handy stuck after CM update
I'm really in need of some big help. I tried to update my phone today (HTC One with OneDroid), because it said there would be a new stable (!) version. So I installed it, but then after rebooting the device, the message "Unfortunately, the process com.android.phone has stopped." pops up. I can press "OK", but it just appears again, and again, and again. I already had this bug a few times, but I was able to solve it with flashing the rom again.
To the main problem: My PC won't recognize the phone, I'm not able to load a new ROM on the sd card. Fastboot USB also doesn't seem to work.
Also, my SIM-Card doesn't seem to work, obviously there must a connection between the error message and this failure.
How can I make it visible on my PC (WIN 7 btw.) so I can load a new ROM on the phone or how can I make the error disappear?
HTC undlocked via HTC Dev.
Already tried factory reset, bug still existing, so I guess it's because of the actually unstable ROM. How can I make my PC recognize the phone?
Thanks in advance!
