Re: A1466 bios passWORD help

Did you erase flash, write and then verify the new ROM file?
You may also need to do a option-cmd-p-r three boots to clear any previous settings.

Yes, I did erase the flash, and reset with ALT, CMD, P, R, still only fan runs, no lights, but I downloaded another bios for the same motherboard it switches on but I cannot install the OS,, it is very very slow, what can I do now please help me I am in trouble the owner wants his MAC!!

Thanks peste it works but keeps asking me for a pin code when i try internet recovery

BIOS guides, methods, resources and tools -> https://www.badcaps.net/forum/showthread.php?t=103526 3. Password removal by laptop brand -> https://www.badcaps.net/forum/showpo...42&postcount=4
3.2. Apple -> 3.2.2. 2012 to 2017

For 2012 to 2017 machines, BIOS must be edited and reflashed to clear the password. There are 2 methods for this:

Clear out the whole SVS store. There are other stuff in this store, no idea what they are for so better avoid doing this.
Invalidate the CBF2CC32 NVRAM variable in that SVS store which contains the encrypted password. You just have to change one bit in its name, so like replace the C with an A or whatever. Note that strings are UCS-2 encoded, so in the hex editor it'll show up as 0x43 0x00 0x42 0x00 0x46 0x00 etc.

If there is an iCloud pin, you need to perform 3x PRAM reset after removing password. If FindMyMac is still enabled, you have to reinstall macOS while being disconnected from the Internet, then reconnect after logging in and bind to a new Apple account.

Re: A1466 bios passWORD help

I've removed the password from the bin file.
Let us know if this works.

Find one with clean ME firmware, use the forum search https://www.badcaps.net/forum/showth...A1466+EMC+2925 .You will need to edit in your own serial number thats on the case, and correct the fsys checksum ,see the video linked here

Hey guys! Is there someone who has A1466 EMC 2925 1.6GHz 8GB working clean bios? Sadly the original is useless, damaged. Corrosion on efi connector...
