The phone will not turn on no matter what. It is not recognized by a computer, I believe that the USB port is broken. I have been having problems with the phone since replacing the screen a few months ago. The phone battery died, and it never came back on. When put on my Nokia DT-900 wireless charger, the white light on the charger comes on, but not the light on the phone. I don't know what to do at this point, any advice or help would be greatly appreciated.
