Hello I need some help, I am currently trying to mod my bios using a mix of AMIBCP tool and UEFITool. I am not sure how to get passed hp's signature restriction. My original plan was to use hp's bios recovery usb but replace the stock bios with my modded bios but it errors out every time I try flashing. Any ideas on what to do, also any suggestions on how to mod the bios in the first place, im not confident in my abilities. I can send the bios or a link to hp's drivers for my laptop looking up my laptop should allow you to find it tho. All I am trying to do with my mod is allow for me to open up the hidden advanced menu so i can mess with the fclk clock and my ram. Any help on any part would be greatly appreciated. If you have more questions that you need me to answer before you can help also let me know I will answer to the best of my abilities.

Well its only erroring out because the signature file that comes with the bios doesnt match anymore, i tested just flashing the normal bios and it works so that method would work if HP's security could be bypassed. How do you suggest I do it instead?

alright here is the exact picture of the error, i can re do the bios flash to get another log file if additional info is needed.

Well the bios utility inside of windows asks if i want to do a bios update, make a recovery usb, or download the bios. So i made a recovery usb then i replaced the bios that it had included with the modded bios i made. In windows everything is fine. Then i go to use it and it opens up and starts trying to update the bios this is what it says on the screen. Then It lets me exit and i go back into windows and on the usb drive is a log txt file with the picture i sent previously. If you want I can send u a link to the driver page if you want to see and download the bios utility for urself?

Bios update would just kick me out of windows and update the bios I can try it again but i was not sure on how to swap in my edited bios. I will try it again and let u know if i can manage that. Do you think it would work going through this rather than the usb method, wouldnt it just have the same signature checks?

I checked it does not save the file to any spot on my drive that i am able to access i have even looked through hidden system files like System Volume Information or in where windows stores the drivers. No luck with either.

Sure id love it if you could do that. Also in my msg above i was referring to the option u mentioned in ur previous msg.

"It would, if I don't patch. Do you want me to send you an edited bios update?" Do you need me to send anything to you for u to be able to do that?
