Reflashed Surface Pro 4 BIOS to remove UEFI password. Now it boots SLOW

I have a Surface Pro 4 that was UEFI locked.

It worked normally, but you just couldn't get into BIOS without a password.

I stole the BIOS from another identical board and flashed it. I didn't edit the BIOS at all.

Now when I turn it on it takes 30 seconds to get Surface logo (before I flashed it took 1 second)

Then it takes about 15 seconds before you get the Windows 10 spinning dots. (normally it's almost immediate)

Once it's booted into Windows 10 it runs normally. I have also tried a fresh install of Win 10 since the BIOS flash.


I am not very experienced with BIOS flashing. Was there something I needed to edit in the donor BIOS to make this work correctly? Clear ME?

You should upload original locked bios, get it unlocked and flash that.

Surface Pro 4 - UEFI password removal please?

Could someone remove the password from this dump?

Also, if you have time can you point me to any resources that I can learn to do it myself?

No, it's still locked.

I have a clean ME dump for this BIOS. Would that help?

I can't use the clean ME BIOS directly though, because it makes the touch screen stop working. There must be something in the original BIOS that allows touch to function... I somehow need to combine them I think.

Nah, don't mess with ME and such.
Try this.

YES! Thank you.

Touch works, starts up fast, and no more BIOS password.

Can you tell me how you did it?

EDIT: I ran it though hex compare. The only difference between the two files are a single character at offset 00606620. Is that all it takes?

Re: Surface Pro 4 - UEFI password removal please?

Yes, that's all it takes. The tricky part is knowing the exact byte to modify
