MacBook Air 2015 (820-00165-A)

[andrew_puma]

Hello, I need help. Brought to repair the macbook with the problem there is no way to install osx. The password from Efi was lost. In another service, the password was reset. But the serial numbers do not match the back cover. another dump is recorded. there is no native.
The installation hangs.
What to do?
sorry for my bad english

The BIOS got fucked with. Try to get the original dump. You need the original ME region for it to work properly.
You could try to put a clean ME but it's known to cause issues sometimes on Macbooks.

There is no original dump. Filled dump with pure ME. But without result. the installation also does not start.
Can you check my dump that I wrote down?

Try the Blank Board Serialiser to program a new serial.

Try to look for small components with tiny corrosion, especially on some mosfets. I had similar issues when Q8062 had corrosion on it. Had to replace it with the donor board component.
Also, although on different board, I had the similar issue with boot freezing on 820-3662, in that case I had to replace and rewire the Q1920 due to few pads being ripped off.
