[BlueGold]

Hey i have a Macbook Mainboard here 820-01700-A.

It was a waterdamage. i clean all and all looks ok now.
I have dfu i tried dfu revive. but failed with (AMRestoreErrorDomain error -1)

did you know what i am missing?

Any chance for data? can i swap t2 and nand to new mainboard?

Something more affected by corrosion for sure.
Possibly corroded traces, or passive components (resistors, capacitors).
May also have accumulated crap underneath some BGA chips.

T2 chip? nands?

Data is encrypted and the key is stored into T2.
You can try swaping both T2 and NAND at same time, but not sure if helps.
T2 will detect all the changes in the peripherals and may enter into recovery.
