Unfotunatley, the process com.android.phone has stopped.

Hello,

My HTC ONE M8 displays the message "Unfotunatley, the process com.android.phone has stopped."

I never installed any custom rom or tampered the software, I allready applied a factory reset but i diddn´t have a effect.

It also seems that the phone won't charge... Tried several different chargers...

On the HBOOT screen it shows me this information:

***Software status: Official ***
*** Locked ***

Is there a way to fix the phone without losing it's warranty?
