Hello

Check for short capacitors near the NAND. (for example: C0634)

Had the exact problem with U1202 getting really hot and of the 11 caps C0634 were the one short! Best post ever, big thanks!

Impressive Pallle, why did you feel it was the C0634, I mean what was the thinking process?

Thank you.

Hello

Because the PMIC was very hot after press the power button, the short is not in PP_VCC_MAIN or PP_BATT_VCC and the device not turn on, then the problem around the processor or NAND.
I found the C0634 problem previously and repaired with this issue 3-4 iphone6.

Curious why you decided has to be either processor or nand? Couldn't it have been any other chip/area that the pmic provides power to that's being shorted to ground?
