I don’t know how to make a normal backup of my BIOS oops! lol
Check Section D, and make a full spi dump with the Intel FPT tool from ME11 tools package

Hi @MeatWar
I read the [Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing as you recommended and I dumped the BIOS region using FPT tool. So I proceeded to mod the bios section and tried to flash it and again faced the secure flash issue. So I have tried to unlock the BIOS of ASUS Rog Flow Z13(GZ301VV) using the EFI shell from https://winraid.level1techs.com/uploads/short-url/7V4Ii92PefJm0ZRusL3oAIGHgIe.rar to set the variable for BIOS lock. But the EFI shell doesn’t run on my laptop. It ran on older PCs.
How can I find the higher version of the EFI shell that can run on my laptop. Or is there any other way to unlock the BIOS? There is no “pinmod” on my laptop motherboard.
RU.EXE + RU.EFI

Thank you, @MeatWar for your reply. I will try to find answer from your recommendation and if I get any result, I will let you know. Thanks again.
Hi MeatWar
Thank you for your advice. I found valuable info from your recommendation. But I still got an issue. I described it on [Request] Gigabyte Aero 15 OLED BIOS unlocked #664.
Could you give me advice on that? Thank you in advance.
Laptops are not my “strongest” area… in fact i kind “hate” laptop systems…wast of money especially for gamers, good for work only.
Setting a value in those variables using RU is a temporary solution for dumping with unlocked values, as soon as the system powers down/reboot the default are restored.
So most cases what users do is to flash that unlocked dump to the SPI IC, when possible with FPT tool or SPI programmer, other solution is to edit the FD by HEX editor and flashing with SPI programmer or FIT tool on ME region if FPT tool can write to the ME region only.
All these are RISK operations that can lead to a death system,
cant help more on this, good luck.
