    Hi guys, i have one Macbook pro 13 Retina Late 2013 and he have broke EFI (BIOS) chip, i solder him out and make original dump back up via my mini programmer, all what i need good and clean EFI dump for my mac.

    Info about my system: Macbook pro 13 Retina Late 2013

    Model: A1502
    EMC: 2678

    Motherboard model: 820-3536-A

    Please help me to find that file, apple.com doesn't content anything like that, i don't need BIOS update file with .dmg extension,i need .bin with dump and of course without EFI lock.

    If people are interesting how to do that i can make post with photo and explanation how to open, disassemble, and chip programming.

    to my knowledge no dump files are available and you would also need to change the proprietary TPM chip apple uses to verify its Apples hardware on the motherboard to match it. ive cooked one once and the only option was a board replacement. the ONLY people I know good with the firmware are the coders over at various hackintosh forums

    I make investigation and find some solution, i make back up from my original EFI image and modify him via hex editor and delete password line in .bin file, it was a little bit tricky but finaly i do that. Today i will program my chip one more time with mod EFI file and solder back on mobo.

    Later i tell if it suceesfull or not.
