currently the device asks for bitlocker key or uefi system password no other option.
So i don't think i can enter EFI shell since USB boot is disabled.
The only solutions i see are.
1. Remove the internal ssd format and fresh install win10 then use as is without Linux and USB boot lock UEFI menu lock.
2. Remove the internal ssd format and fresh install win10 then remove the UEFI/BIOS chip and try to get the password removed somehow to gain full access to UEFI menu(not sure it is possible for this model since no resource online has declared success everyone faced issues even after multiple trial and errors.).

I've tried to do everything that DeathBringer suggested, but nothing seems to work for me. I get the following error:

error: ../../grub-core/fs/fshelp.c/258:file '/efi/grub/i386-pc/normal.mod' not found.

Hello there DeathBringer, can you please tell me how to decrypt the password from the image? I found a way to dump the bios image without creating the bootable USB drive with UEFI Shell & CHIPSEC. I was able to ran 'fptw64' from a live cd to dump the image. thanks in advance.

Firmware for all these devices don't store passwords in coded form. They have only hashes.

Hey! ..be honest, if you are here to share some of the little knowledge that you know, make sure you do it right, otherwise don't even make a move.

I've been reading a few of your comments, and what you did is make users do a lot of things they did not had to do. and for what I know there is a Surface bios password decryptor out there, and many are already using it because they already have the tool. I know few forums with users who are helping users to the decrypt the bios on surface 1, 2, 3, 4, etc. so please don't come telling me the same junk you already told everyone here: "No, password can't be decrypted in this case." ..there are only to answers. 1.) you have no idea how is done. 2.) you're too selfish to share. thats all. but thanks anyway.

I just want to leave this forum by telling all of those few that were following this guys recommendations.. that you don't have to do all of that in order to bring the password from the bios. you do not need to read the aspects of the surface. the main issue you already know is that the surface is bios locked thats all. so the next step is to unlock it, that it. and for that you will need to get the bios image. anyway.
