========================================
Was watching youtube when phone goes blank. Any combination of power/volume keys did not turn on the phone. Charging the phone and no red indicator light. Connected to a PC and device was identified as "QUSB_BULK_CID" followed by a serial number. There is an XDA thread on flashing firmware in EDL mode and I tried that. But it did not help me. Looks like an hardware issue.
Last year, I had a problem with camera and solution was to replace motherboard under warranty. Now this.. hesitant to visit service center again, no point in wasting time in such **** hardware..
