First again flash phone (MCU+PPM) and then with "FAID" and "repair IMEI" and possible "unlock with eproms 3.1" ...if still same problem again change PA!

changing PA , can cause phone not to power on again.
please, try a new battery on your phone .

post your result .............

if nor properly applied, this can cause no power on problem.

Friends,

I have seen people saying, check VBATT to PA.

What I want to know is.......should there be continuity? or should there actually be 3.6 volts on pins of PA?

I have measured in 3 or 4 phones today, and all of them had continuity, but none of them had voltage of 3.6....any suggestions?

Regards,

Raja3333
