Got this board slightly water damaged, It is stuck at 20V 0A.

PPBUS_G3H is 12,60V
PP3V3_S5 is 0V and no short diode mode is

PP3V3_G3H_PMU_VDDMAIN 3.3V
PP1V1_SLPS2R 1.1V
PP1V1_SLPDDR 1.1V
PP3V3_G3H_RTC 3.3V
PP1V8_SLPS2R 1.8V
PP3V3_AWAKE 3.3V
PP5V_G3S 5V
PMU_ONOFF_L 3.3 V

I must admit I really don't know at this point what signals are required for the PMIC to switch PP3V3_S5 or what condition before even getting PP3V3_S5.

Thanks

Yes I actually started with a good inspection on both sides of the board I don't see any corrosion.
I tried DFU mode Revive and Restore and it ends up with Error 4005 (can't restore the target ...gave up waiting)
Nothing change...Thanks
