820-3437 donor board serial number

[Blackmambo90]

Hi there, i am swapping a board on a 2017 mac air with a donor one, is it enough to replace the eeprom on it with the original to have the right sn and all the rest or there is more in to it?
Or maybe fix the dump from the donor board?

Replacing the SPI chip, will generate weird ME issues.
You need to edit the BIOS of donor board, change the serial number and fix Fsys checksum.
We have detailed information on the forum; even Youtube videos uploaded.
Use Medusa programmer, or UEFITool software.

Yes, sorry, wrote my question before looking it up

How ever now i see there will be issues with checksum

Is there a way to do it manually with out medusa?
