You need to program BIOS
The file I sent you is BIOS but it is damaged, right?
yes
program new bios
program new bios
I already wrote the file you sent me, but I did it like I write the unlocked bin file.
I don't know if it's the same as programming the BIOS?
But with that file it doesn't turn on, only with the backup locked.
With the same program that I used to make a backup as I always do.
After reading and saving the backup, do I delete the BIOS and write a new file?
just program new bios file bro !
is this the new one?
no efi pin anymore?
If it is this one, I already programmed it and it does not turn on with this one
send main 4MB bios backup
I think the file is damaged because it doesn't start, it just keeps loading on the Apple and doesn't finish starting.
Do you have a bios bin from another one that we can use?
