Schematics A2141 820-01700 X970

the macbook was not turning on.

had a burnt mark on u8600 near it's corner

it wouldn't go from 5v to 20v

I applied 8v to ppbus_g3h, after that the Mac went from 5v to 20v

but u8600 was getting very hot, I took it out and tested it out this NAND has internal short to GND on PP1V8_SSD1. so bye bye DATA recovery.

did anyone here has fixed SSD problems on T2 MacBooks?

I think I somehow damaged U4770 trying to use a modded CH341A to pull .bin, I've done it a few times already no problem and I don't see any damage but I kept gettting errors detecting the chip (MX25U3235F) and after hours of messing with progammer and software I checked the chip and pin 2 value is off, I wasn't able to read so my question is it possible to purchase a new chip and flash with new .bin?

The 4mb file you see is just non-BIOS information.
