Ask Need Help Restoring Erased BIOS on Surface Pro 1796 (Password Locked)

[vanescar]

Hi everyone,
I have a Microsoft Surface Pro (model 1796) that was asking for a BIOS password at startup. I tried to fix this by reprogramming the BIOS, but I accidentally erased its entire contents in the process. Now I have no original BIOS (with password) to restore from, and I’m stuck.

Has anyone faced a similar issue or knows how to recover/restore the BIOS on a Surface Pro once it’s been wiped? Any suggestions, tools, or methods would be greatly appreciated. Thanks in advance!

I successfully loaded the firmware you posted, but it doesn’t see the internal drive. I also need to recover the data—how can I do that?
Look at the picture—it detects a drive, but it’s showing zero bits.

If SSD M2 it only works with Original BIOS

Happy New Year 2025!!

This isn't a laptop; it doesn't have an M.2 slot, and the SSD is soldered onto the motherboard. How can I solve this problem...?

Unfortunately, I messed up while trying to make a backup and used the wrong program, which ended up deleting the content.

now only problem SSD ?

Touch and other things work normally

I broke the flex cable for the touchscreen, so I can't test it. Anyway, for the moment, the only problem is that the HDD isn't being detected.

If you don't have the original BIOS, you need to buy a $35 patch to fix it

Sorry for not getting back to you earlier, but I have a problem. I can’t program the chip with your new instructions; I’m getting various errors and it doesn’t recognize the pins during verification. I think it might be damaged?

password deleted, but I can't boot the installed system, it seems I don't recognize the disk, could it be broken?
