The serial was replaced, look for 123456789012 and replace it to your serial
Im about to try this one now because mine gives AHT Error 5101D, and no friggin info on the net about this code. Its NOT related to Firewall because it isn't connected to LAN/WIFI.
I've reballed the SMC, but same issue. So the only thing to try is BIOS/EFI reflash with another one. Already put my original SSN in to it.

Although that got rid of AHT Error 5101D, its in a different keyboard language and wont accept my WiFi password.
Also wont detect SSD. Pretty bad BIOS you put up there.
