EDIT: No “bros” here sir and better things to do with my time.
I’ve tried everything, bro, if I send you the .bin file and the pe32 can you do it for me?
What board? Bios unlock is a rather easy procedure. Basic steps:
- Open Bios file in Uefitool
- Find setup ffs program in said bios and drill down till you find the actual efi base program
- Extract it as is
- Use an ifr dump utility to extract the data
- Open the data file in your favorite text editor
- Search for ‘Lock’ untill you find the matching variable thats on the menu option for ‘Lock’. On mine if was x93.
- Then you have to load up an efi shell from bios and type:
Setup_var x93 0x00
The efi shell file you can find on this site if you look hard enough. The protected range registers is a lot harder and may be over come by jumping an FD jumper on certain boards. I also read that certain older flash utilities sometimes also can get around it but could brick the board. Manufacturers like Hp or Lenovo however make it very difficult as they dont want people causing warranty issues. I tried to do this on an Hp board and gave up. Recommend you use Chatgpt. Know thats contravercial here but I read that some hacker used it succesfully to flash linux on some embedded system so its not without benefit. I use it all the time now.

Thanks for the tip, I’ll try it here and get back to you.
