After carefuly reheating pcb,phone work without any problem but not ringing.
Then I have put in ultrasonic both,3-4 time washing and now can't powering on,phone is dead!
I have one time flashing after that,with main and modem flashes,but phone is still dead.

@rambo amadeus

It seems all the Ultrasonic properly have "vibrated" something loose at the board.

I would suggest the folowing

1 : Check if battery contacts are shorted !! Maybe the PA have gone to the eternal silicon fields because of all the bathing, and you by mistake did not dry the board proberly !

2 : The second thing to check on this board is the RF module. If it's a older version board, it proberly unglued !! Maybe some of the solder balls have lost connnection with the board !! Try first to reflow it with flux. Since the RF Module also are involved in the power up seqence !!

3 : Try to full restore the software. Depends on which flasher you use though, SEF or DIV or any other ?? Please post and I'll get back to you. If you use SEF you can check this thread here
