    help!! Clean key and ME region imac A1312.

    Greetings friends, please I need your help, an iMac A1312 2010 with EFi key arrives at my workshop, but I do not feel confident to edit the efi bios, I am a newbie, I need to clear the key and the ME region zone.
    Greetings and a fraternal hug.

    PS: it is original bios read with the programmer.

    Change RAM configuration and do 3x PRAM reset.

      Hello friends, a fraternal hug, I request your help, a 27 "imac arrived for service, the client accidentally blocked his computer but has problems activating it, he does not remember the secret words !! 😪.
      I have taken a backup of the original BIOS, I have followed the guides, but I see that the $ SVS is not found! Please, someone help me by modifying the bios, cleaning ME regios and efi lock.

          I have done the process, but when I get the BIOS backup I see that it is different, it is UEFI !!, and it does not work.

              I have the original BIOS, just make a copy, I don't have the motherboard number, I'm going to disarm, but the bios is shared.

                I have the same problem.
                After I have tried to change the ram and the combination keys it didn't work.
                So I decided to do it by the hardware methode. I did that before a few time on mackbooks.

                But with this one I can't find $svs in the original bios dump file (hexadicimal)

                board model is an 820-2828-A A1312

                Any help would be great!
