    Hello, I need an unlocked bios for MacBook Pro A1708, EMC 3164, Serial number: C02VQNXAHV22, unfortunately the current memory is damaged and it is not possible to read the old firmware, the previous memory had an EFI lock.

    Thank you in advance
    Post #56 has clean ME firmware and is a good bios to use, just need to add your serial to that bios and change the fsys checksum.

      I did everything like in the video and unfortunately the firmware does not want to be uploaded, an error appears during verification in the programming program

            Unfortunately, after soldering the chip, the MacBook does not turn on and shows no signs of life, I only noticed that the disk heats up terribly

              The disk meaning the bios chip ? , is the replacement chip the same voltage at the old one

                        sorry that I've missed my introduction for new board members. Would someone please be so kind, to have a look on the locked EFI/BIOS (... and unlock it)?

                            Hello Masters.

                            I got 1 bios working with my macbook pro A1708. It got display. But now after installing new Os High Sierra 13.6 it is very slow on booting and legging in os too. some keys are not working in os. In the recovery every key works fine. Can some one tell me the problem? Is it ME Region Problem?
