Hello!
This macbook pro got repaired (water damaged) finally figured out what was wrong with it, (visible water damage in SSD areas). Replaced a few caps and now we got power then after a day or so the power stopped. Tested the board it gets 20.0V and then rises to 1.22 amps then restarts. So we tried DFU mode and it was able to boot into DFU mode and the board would get 2.89 amps. Nextly it wont do this without DFU. Tried doing a restore and also revive and DFU mode gives me and ERROR that the restore cannot go into recovery mode so yup SSD is the issue.
Tested caps C9074,C9073 and so on for this area for PPBUS_G3H_SSD0 and I am getting voltage on this rail side.
But when trying to test for voltage on PP2v5_NAND_SSD0
There is no voltage present and the entire row of
C9094,C9095,C9096, etc. have no voltage present. So I am assuming there is a short in this area that has failed. can someone help me understand PP2v5_NAND_SSD0 in this area? Also the board gets power and gets hot and turns on in loop sequence which it lets me get into DFU mode but this means the recovery is not working because portion of the SSD area is not working. Any suggestions?
