    Macbook Unlock Bios help

    Hi good people of badcaps,

    i would like to learn how to unlock Macbook Efi. I watched a tutorial on youtube, but still there are some things i am not sure about.

    I have a board from Macbook Air 820-00165-a with 8gb ram. Does ram and proc. determine which dump efi should i use? I found one clean one on the web, that one is on the picture where serial starts with C02... , mine board starts with C1MR...

    I replace the serial number on the clean one that i found on the web and it should work or is there something else that must be done?

    Thanks

              imranromi, i tried this bios, but it is locked as original. I tried to reset PRAM, but as i see it can not be reseted, until bios lock is on.

                          [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                          by zenius
                          Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                          Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                          Dell inspirion 5775 bios "Unlock Setup fail"
                          by remizbushka
                          Hi sirs. please help
                          Dell Inspiron 5775 bios locked "Unlock Setup fail"

                          ​
                          After generating the Password Recovery code, I go to the “Security” tab - “Locked Settings” - it says “Unlock Settings? I tried many wrong passwords and it shows an error to unlock settings [ Press any key ].
                          What I did:
                          I read the bios dump.
                          Downloaded the bios update to 1.6.0 from the official Dell website, extracted the dump from it, updated the bios, but the problem persisted. Please help me to solve the problem....

                          Dell Latitude 7420 BIOS Unlock Gone Wrong
                          by Jeff'sTech
                          Hello everyone.

                          I have come here with a rather specific question. I was given a Dell Latitude 7420 laptop with a busted screen, and wanted to see if I could refurbish it into my daily driver. I wanted to experiment and see if a 2-in-1 display would work as the chassis of the laptop and 2-in-1 7420 looked identical. I threw in the display and my hypothesis was correct, however, I was greeted with a locked BIOS and since I didn't know the password, I figured I'd try to unlock it somehow. I bought one of those POGO pin probe things for my CH341A programmer so I could read and make...
