• In firmwares for systems from 2015 and later, you'll see "ME Region" at the top level of the hierarchy displayed upon loading the file. Right click on "ME Region", select "Extract As Is", and save that file with a .rgn extension --> REPOSITORY.RGN

I thing this is the ME region XD (https://logi.wiki/index.php/Clean_EFI_ME_Region) I see on this link. I will trying again.

post the S/N...

Dear friends., Working on MacBook Air A1466. All works fine. I restored the MacBook to macOS Monterey. Upon setup I just noticed that this is locked to a school & request me to restore to school data. I re-build the BIOS Bin files & again it is asking for the school account. Isn't this info stored on the EEPROM or somewhere else. Have I done something wrong or it going with the Serial # written onto the BIOS. Can someone kindly check what wrong am I doing as the school info is not erasing. Thanks in advance. MacBoook Air A1466 Serial # FVFWMZNBJ1WK EMC 3178 Logic Board # 820-00165-A

Don't worry dear., I forgot to do that PRAM reset. All data earsed & registered to a New user. BTW if someone can explains, is there another EEPROM hidden on the logic board, mean where does the previous data sit for a while???? I would appreciate if someone knows this & informs all the interested ones. Thanks

here it should boot faster now.

Hey! Thanks a lot, Rex98! 👏🏼👏🏼👏🏼

Hello everybody: I have a problem in the bench with an A1466. It takes a lot of time since you push the PWR until the chime sounds. After that, the machine runs perfectly. But it takes 20...30 secs to gimme the chime sound. I thought maybe it will be a problem in the BIOS (corrupted?). This machine is an A1466 EMC3178 (it has Big Sur, so maybe the firmware was updated in the process of Big Sur installation, because the original EMC was EMC2678). I'll go to update here the bin file which is (suposedly) giving me this error, so I beg your help. TIA for your always invaluable help.

The machine data is:

MacBook Air A1466 SN is: FVHYHWZAJ1WK.You can also read in the back cover EMC3178. The MoBo is 820-00165-A.
It must be the latest batch, because it has Big Sur installed without tricks. It has 8Gb RAM, and only 120Gb SSD (I'm going to change it, amongst other things, like the startup delay problem...annoying!).

EDIT: This happens even without internal SSD. Even when you reset NVRAM; the time between chimes is veeeery looong. The curious thing is that, once started, the machine works like a charm (well...with Big Sur...I don't like it, but it works normally). I was thinking about the SMC reset signal, which can be "delayed" by any reason. But all signals in the scope appears well, compared to an older, working normally board (older, of course).

here it should boot faster now.
