Re: Microsoft Surface Pro 4 UEFI Unlock Request

No, I never got anywhere with it as far as unlocking the BIOS. Other than that it worked fine in Windows, but I ended up not using it very much and sold it to someone else on eBay.

The BIOS is pretty limited in settings you can adjust anyway on those devices. So you aren't missing much even if you are locked out of it, basically just secure boot. I think if I get another device in the future it will be a regular laptop.

Re: Microsoft Surface Pro 4 UEFI Unlock Request



Hi, thanks for your reply. I have tried without the -BIOS before and it complained it couldn't read that flash area or something to that affect.

I believe after writing to another member here with the same issue, that iamromroni is correct and the only way to get the full dump is to open up the tablet and read it using a physical programmer.

However, the Surface Pro 4 from what I've read is extremely difficult and time-consuming to get into without damaging it, so I'm not willing to go...

Re: Microsoft Surface Pro 4 UEFI Unlock Request



Hi imranromi, thanks for your reply. I've been trying all day but the FPT program refuses to output more than the 10240kb as shown in the attached screenshot. FPT reads the total size of the BIOS as 16384kb as you say but when I run the dump command it just not pulling all of it.

I've also been unable to find another BIOS backup tool that works on Windows 10 and the Surface Pro 4.

Any ideas?...

Microsoft Surface Pro 4 UEFI Unlock Request

Hello,

Can someone please take a look at my BIOS dump for my Surface Pro 4 and see if they can remove the password?

Re: Microsoft Surface Pro 4 clean bios backup

Hey, I'm a noob here, but it sounds like some others have had the same problem I'm having. I have a Surface Pro 4 and can't get into the UEFI BIOS settings due to a forgotten password. I can boot into Windows 10 just fine but can't make changes to the UEFI settings.

Would flashing one of these "clean" BIOSes fix that problem? If so, how do you go about flashing it manually? I've downloaded a few of them but they all seem to be of varying sizes, but the majority are 16,384KB. However, even this is significantly...
