    Dell Optiplex Micro Plus 7020 Help needed: BIOS Clean ME and BootGuard Disable

    Dell Optiplex Micro Plus 7020

    Reg Model: D15U

    Service Tag: 8L0LG94

    Express: 18685049224

    Motherboard 232014-1 N25VK$HA

    Hi everyone,
    I'm facing a bit of a situation here and would appreciate some help from the experts.
    I received a unit that was BIOS password protected. Unfortunately, during the initial dump, there was a verification error that I didn't catch in time, resulting in a corrupted original file. I tried flashing another BIOS chip with a different dump, but the device is now a "no power/no display" state.
    Fortunately, I have an identical unit (same model, same motherboard version/revision) and I have just performed a verified backup of its working BIOS.

    I need help with two things on this working dump:
    1. Clean ME Region: To ensure compatibility and avoid initialization delays or shutdown issues.
    2. Disable BootGuard: If possible, to allow the modified BIOS to run without signature issues.

    I have attached the working dump from the twin machine below.
    Thanks in advance for any help! And a friendly reminder to everyone: always double-check your verify logs before erasing the chip!

    The bios is split across two chips. The ME firmware can`t be cleaned without joining the two together. Post the other dump.

        Dell OptiPlex Micro Plus 7020 BIOS password removal
        by orizon
        Hi everyone,

        I need help clearing the BIOS master password on a Dell OptiPlex Micro Plus 7020.
        I have already extracted the 16MB dump using a CH341A Pro programmer and a SOIC8 clip. The NVRAM area seems to be encrypted.

        - Model: Dell OptiPlex Micro Plus 7020
        - Chip size: 16MB (128Mb)
        - BIOS Chip: Winbond 25Q128JV

        I've attached my original locked dump. Could someone please patch it or clear the password for me?

        Thank you so much in advance!...
