A2159 (820-01598) no pp3v3_s5

[vinse]

hello guys i'm working on A2159 board 820-01598
this board was waterdamage
the U6903 was corroded i remove and reballed it (no new spar for change )
so the PP3V3_G3H_RTC is back and steady
for troubleshoot i use the
power diagram from this forum

i get 20v and all voltages from PPBUS to PMU_ONOFF_L (3.3)
but no PP3v3_S5 and no other voltage after that .

i tryed to go to dfu mode but no success ( to restor the T2 )

voltage without battery goes from 0,0 to 0,1000 and back to 0,0890
with battery act as charging but no boot and the trackpad is cliking

if try to restore it with apple configuration. Im able to get it into DFU mode but when I start restoring it come up with the fault:
The operation couldn't be completed. (AMRestoreErrorDomain error 9 - Failed to receive message from device, might be connection problem with USB host. (Communication error, possibly USB disconnection)) [AMRestoreErrorDomain – 0x9 (9)]
And the fan start to work for 10-20 seconds on the dead MacBook. Any idea please? Thanks
