Just read first post of this thread carefully.

 

• Put the modified BIOS, the prr.exe tool and the fpt.exe (along with the fparts.txt file) on the root of your prepared DOS bootable USB drive, restart your system and boot from that drive. 

 

• Execute the prr.exe, if you don't get an error message continue by pressing enter. Then flash the bios by using this command (filename.bin obviously needs to be replaced with the name of the file you want to flash). If you can't remember the name of your file, use the command dir to display all the files on your drive. Flash with this:
   

  
  fpt.exe -f filename.bin -bios

  NOTE: The name of the BIOS file mustn't exceed eight characters (not counting the extension)! That's a DOS limit, so make sure the name of your file isn't too long. Wait until the process is done. After flashing it will verify the data, in case there's something wrong with the flashed data it will tell you. In that case don't reboot, just flash again.

 I clearly didn't understand the execute the prr.exe part, that's what I wasn't doing got it working now Thanks for Help! now I can finally do whatever I want without being limited

Hi!

Just run HP tool as Administrator.

 

 

Thanks that did the trick, now Im getting the error "error 28: protected range register" how do I get past that? also, "PBR GBE regions does not exist" which I think isn't that relevant 

Hello, I'm trying to unlock my bios on my Lenovo y500 and I'm kinda stuck at the first step where I need to make a DOS USB drive. I am getting the error message "device media is write protected" when I try to use the HP tool and I googled a bunch with no luck. are you able to help me with it?

Pretty sure 5 actual posts

Is there a guide for this? it would be amazing If i can get this working since my Y500 is basically falls under the "PC" category 

will this work with the latest macOS update? and on the GT 750m ?

Sorry for being dumb but will this work with a 750m? i didnt see it listed so I asked

Im gonna try this soon
