I purchased AERO 16 YE5 this time.
It has i9-12900hk (alder lake) and uses 16.0 for FPT.
With FPT 16.0. The DUMP.ROM was created by entering the FPTW.EXE-BIOS-DUMP.ROM command.
This was modified through UEFITOOL 0.28 and IFREXTRACTOR, which was stored as DUMP2.ROM. (For the purpose of releasing the hidden function)
FPTW after modification.I tried to flash EXE-BIOS-F, but it was blocked by error 167 FPRR.
I'm ru.efi and grubshell.The values of fprr and bioslock were modified using efi. It was confirmed as 0x73D for FPRR and 0X1C for BIOS LOCK. (I already disabled SCCUREBOOT OPTIONS.)
(Check with setup IFR.TXT)
When writing ru.efi, go to the corresponding value, enter 00, and CTRL + W.
(When writing ru, writing was done without any problems.)
When using GRUBSHELL.EFI, SETUP_VAR 0x73d 0x0 was used.
(I received the phrase can't set variable using efi here.)

This link is the creation of the DUMP.ROM of the notebook using fptw.exe-d biosregmod.bin-bios.

What can I do to FPRR disable?
It's only way to do ch341a programmer?
Above all, I wonder what I set wrong.


Edit by Fernando: Thread title customized and shortened

I FOUND SOMETHING WRONG.

0x3D954 Form: UEFI Variables Protection, Form ID: 0x284E {01 86 4E 28 01 1F}
0x3D95A Setting: Password protection of Runtime Variables, Variable: 0xC24 {05 91 05 1F 06 1F 1D 05 01 00 24 0C 10 10 00 01 00}

I think it makes cannot use ru.efi(for change pchsetup). how to disable it?
