820-3435-b model a1465
the chip is broken and unreadable
i have used many dumps i found online with many available chips but the machine refuse to turn on!
I have gotten many chips from different board of different model but cant find chip for same model so i have been using all chips i could lay my hands on but cant get the real chip that broke cos i cant find the name writen on it.

My question is can chip determines the power or the file i programme?

2: Could it be wrong files all that i have been trying ?

I need help pls

You can use UEFITool or FIT (flash image tool) to find the flash chip JEDEC ID in the VSCC table ,then search for it on google.

If you don't have a 820-3435 donor board you can take SPI ROM from 820-3437 donor board.
Of course you'll need to clean ME region and edit serial number, but it will at least turn on (not boot macOS though).
