Macbook A2179 - 820-01958


Device Stuck at Apple Logo. No Chime. No Loading Bar.
PPBUS_G3H is at 12.6V

Sadly i see that the U8700 Nand chip is damaged. There is small corossion on top of it and it has turned a little grayish on that area.
How to check to confirm that it is a NAND issue.

Wont go into Macos Recovery
