Microsoft Surface laptop 4 UEFI password

[Rickkap]

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!

The serial number is wrong, check it again and add the correct one

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 ...

[roli1980]

wouldnt know where to start

[Vesko356]

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

[roli1980]

did that , seems differences in all

[roli1980]

anyone unlock thhis one please

[volinakis]

wouldnt know where to start

as Vesko356 said ... he gave you both the fish and the rod ...
