    Microsoft Surface laptop 4 UEFI password

    Hi all

    I've got 2 Surface 4 laptops that need to be unlocked. Is anybody able to remove password from it or supply a working BIOS? I've had a look around the board and only found one chip that looks to be it a winbond 25R256JWPQ.

    Thanks!

                            Here's the unlocked dump for you too, be careful with the programming, erase the chip first and use verification:

                                  why don't you compare locked dump against unlocked file by Vesko356? You'll figure out how to do it yourself ...

                                  Start by opening the files in hex editor and compare both to see the difference.
