Check network resistor near the LED on the right side of COBBA. Replace it. There are two there, replace the one on top.

To ARC:
If hardware ok, try flash with old SW.
4.02 or 4.18.
I have this problem to last week.
Phone was damaged with sw.
i flashed with 4.35 -> no result , but with 4.02 phone worked correctly :-)
Post you result !
Good Luck
