hello are you still here 
Could you share bios file link. Look mega.nz link is broken. thank
Hi BDMaster
I am trying to modify the bios of ASUS laptop (rog flow z13). I dumped the bios with FPT and found
FPRR VarOffset - 0x73D
BIOS Lock VarOffset - 0x1C
So I used RU.efi to unlock it, that is, I changed the variables in PchSetup and checked if they were changed after reboot.
But I still got this error when I tried to flash the modified bios
Protected range Registers are currently set by bios, preventing flash access. Please contact…
I also disabled the secureboot.
So I tried to unlock Dell OptiPlex 7010 Desktop PC, Intel Core i9-13900K, surprisingly I got the same variable offset for this desktop.
FPRR VarOffset - 0x73D
BIOS Lock VarOffset - 0x1C
And they were already set to 0, but the same error when flashing the bios.
Please teach me what I missed.
