@Kiriazy

More info is needed

Have you flashed the phone, was it the original fault ?

have you checked the DSP with Eeprom Tools ?

@kiriazy

Well, then you'll have to go deeper, but you did not explain more exact what you've been doing to the phone. And you did not try to reflash, you say that you checked the software before ? What was the original fault on this phone ? I need more info than you have given, but you can try to follow this procedure and report back.

Try to follow the service manual, and check the following values :

1 : VB 3.6 V at C227/228

2 : 32.768 KHz at C220 (in my exsperince it does not matter if theres some noise at the edges of the sqaure wave, as long the freq. is ok)

3 : PWRNX at R402 is 3.6 V and drops to 0V during Press of PWR swicth

4 : VBB 2.8 V at C209/211

5 : Vxo 2.8 V at C243

6 : Vcore 1.7 V at L200 at both pads

7 : SLEEPX 2.8 V at J308

8 : PURX 2.8 V at R308 after PWR press

9 : 13 MHz at C303

Do please check all above and report back if some values are not ok.

Regards
