No boot, no itune
I have an iPhone 6 from my daughter no boot.
It stop power on after charging with third party charger, cable was burn....
Since i replace U1700,:
- it was stucked on apple logo if i hold power button during 2sec.
- it's not recognize by itune
- plug and unplug to an official charger is detect by the phone.
i try with new dock flex, same result.
There is no short on vcc_batt and vcc_main
i test this voltage:
PP_GPU 0V ????
RESET_1.8_L 1.77v---- 0.7v before u1700 replace
is it normal that pp_gpu has no voltage before boot(some people say that)?
i test the line but no short (63 Ohms)
do you thinks u1700 is not replace correctly ( it's my 1st microsoldering)
Do you think i need to replace PMIC?
since there is no short on pp_gpu do i need to take off L1213-L1214 to continu testing ?
I dont know what to do first...
If it's normal that pp_gpu has no voltage before boot i need to verify u1700, if not i need to replace PMIC , is it right ?
ps: never third party charger again :-)
