Microsoft Surface laptop 4 UEFI password

[Pucek]

Hello, I have a Surface Laptop 4 with UEFI locked behind a password.

Per my understand according to the guide, for Surface Laptop 4 password cannot be decoded. The password must be removed from the dump and BIOS re-flashed. I would appreciate removing the password and also giving any materials/link regarding Surface Laptop 4 re-flashing - I could not find any details on the forum.

My Laptop:
Model: Surface LAPTOP 4, 15", i7-1185G7, 32gb RAM, 1 TB , 1979 Model
SN: 031098714957

Thank you

thhis file is different from others , looks different

A serial number must be added to every request regardless of what it is, as per the rules.
You have been given enough hints, and you have enough files to compare and find what, where and how it should be done.

Are you going to open a Microsoft dealership there?
How many of these do you have?
Also did you read the rules? Do I have to remind you to add the serial number every time?

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

[roli1980]

[roli1980]

[Vesko356]

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

[roli1980]

wouldnt know where to start

[volinakis]

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

I corrected now motherboard and laptop information.

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