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.
