BUT: there is no Vcc for SHF on c522,no Vsynt 2.8 v on c501 and c504 also no vtcxo on c518,VCO it self is OK.I changed CCOnt 2 times.but I think there is come CUT lines on PCB.it was foil damaged.

@dydycom:
Your post is uselise!

@GSMLight:
If you are sure that RX I/Q lines are ok then try to reclibrate phone with Wintesla.
If you want to make sure that lines are ok then remove CCONT and check lines. But I think you have done it before posting.

PS: I had few phones in past with such problems. I think it is FullFlash guy's work. Only recalibration helped.
