Microsoft Surface Pro 3 UEFI password

[RethoricalCheese]

Hey there!

I've got a few Surfaces in need of an unlock. I have opened one up and here is the dump from it. Is anybody able to remove password from it? I did not manage to find the location of it.

Thanks!

That one I have tried and it works but this way serial number will be changed and that's something I don't want.

Just edit the new working bios with dump dmi info.

Yes, that would be an option but when I just replace UUID and SN on new bios, bitlocker starts crying. When I replace the whole NVRAM on new bios, it will stay locked. Can't find password location in NVRAM.

Thank you very much, works great!

I shall try if I can maybe modify uefi from inside Windows and if I succeed, it will be made into a tool.

No luck there. Although uefitool says that Bios region has read and write access, I am only able to read but not write. Looks like SMI/SMM lock.

Better make your own dump and upload it. I can tell you what the password is.

What is the password string we are finding in the Bin files?? Can anyone inform what Hexa Decimal string are we going to remove to clear the password. Thanks in advance

No need to remove it. Use flash programming tool to read bios region and upload it. I can find and decrypt the password. This way you don't even need to remove the screen to unlock this model.

Did you have a link to a working version of the Flash programing Tool for the Surface 3?

Google TXE ME clean. There should be a result on win-raid forums. There is a link for the tools.

How did you decript a password?
I bought a Surface Pro 3 from ebay, and its BIOS/UEFI is password locked.
Can you help me with step by step instructions?

Thanks.

Hi RethoricalCheese, could you please help decrypting? I dump this BIOS region of my surface pro 3 but since I just learned this thing about UEFI thing, I couldn't get anywhere with that.
Thanks before.
