Default Macbook A1466 A820-00165 CHECK my BIOS please

I have panic CPU caller, I guess it is EFI problem.

Macbook A1466

EMC 3178

A820-00165-A
serial FVFWQ0B7J1WV

May be dump was from different version A1466, because

SPI had traces of soldering and was soldered lack of contact.


In-build apple test is OK (ADP000)
I can choose download source, but during the downloading system crashes.


Here is my SPI dump attached. Help me please.
Thank you in advance.

Try the bios at posts 13 and 44 ,both have clean ME firmware ,all you need to do is add your serial number using a hex editor,and modify the fsys checksum.

https://badcaps.net/forum/showpost.p...43&postcount=5

4.3. Apple
For 2017 and older machines, serial number is stored in Fsys store of BIOS and can be edited with hexadecimal editor. Fsys checksum needs to be fixed afterwards
Search for "ssn", edit the serial number, save, open dump in UEFITool, go to the Fsys store and write down the suggested checksum in the panel on the right. Checksum is 4 bytes at the end of the Fsys store, between one zone of 0x00 either Gaid or another zone of 0xFF, it must be written in reverse order (so last 2 characters from UEFITool must be written first).

Hi,
I replaced BIOS dump, but it gives me nothing.
It is another kind of problem.
