Asus TUF 15 FA506LI :
CPU : Intel i5-10300H
GPU : NVIDIA GeForce GTX 1650
htt–ps:/–/w–w–w.asus.–co–m/uk/supportonly/FX506LI/HelpDesk_BIOS/
I am using the latest 3.07 BIOS.
I would like to have an option unlock CFG and ideally as much hidden features as possible.
For example save advanced mode view, lock fn key and such things if available.
I would like to be able to unlock CFG is possible to be able to undervolt.
I checked CFG as described here:
htt–ps:/–/dortania.github.io/OpenCore-Post-Install/misc/msr-lock.html#what-is-cfg-lock
I get a response that shows the firmware does not support it.
I hope it can be added (was not allowed to add links so removing – should work).
Thank you

by the way, I tried the method under Annex here htt–ps:/–/ww–w.win-raid.com/t455f16-Guide-How-to-flash-a-modded-AMI-UEFI-BIOS.html to make a dump but I cannot boot the USB stick.
in the mean time version 3.09 is out, direct link:

let me know

hi, is there any reason why this shows Win32/YmaccoAA5F trojan in it? Please don’t ask people to run malware. Nobody else asked this before, so I hope you have a really good reason for trying this?
@openminded
Hi friend, i have more better things to do than to make this wrongs you said, this is a false positive as the tool has to read the Eeprom and checks the Vulnerability og the Eeprom, so antivirus thinks that it is a malaware.
You can unpacking the tool by WinRar and can look into what is ! there are a series batch programs to read all the eeprom and ACPI etc.
You can thrust me as i am a modder not a thief …
Let me know

Hi, thank you for the quick response. Apologies, but I have to be careful and I cannot see the publisher and such.
I also cannot check your profile because I cannot see it because of having a recent account I suppose.
I tried to upload the file but the limit is 6mb so it is here : https://www.sendspace.com/file/7cmf5c
It would be great if anyone can share instructions on how to do these things?
I am happy to learn and help out, I have some experience with modifying dsl files.
Thanks for your time, cheers
Hi friend, so your eeprom is write protect …
Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable
Protected Range Registers.

You can try to use RU Shell to change the NVRAM variables to unlock the eeprom :

Hi
I would like to request your help in unlocking BIOS menu for this laptop.
CPU: i5-10300h GPU: GTX1650ti mobile bios ver: latest 310
The dump.rom file is in the link:
Thank you for your help.
Hi, please take some pictures of the menu currently visible in the BIOS
Hi
Thanks for the reply.
I uploaded them here:
I hope these are enough. If not please tell me what else to send.
to you, report the results
I tried to flash it but “Error 167: Protected Range Registers are currently set by BIOS” happened so I’m trying to follow this guide:
“[Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing”
and followed it to where it says “At the EFI Shell, run “setup_var 0x*** 0x^^” command”
but an error happens saying it can’t find the value I found in this file:
“https://drive.google.com/file/d/1MsDRWSH0sMZ1PwXLEaxuGNjUiuTYZUNp/view?usp=sharing”
It seems I’m stuck here.
Can you help me out?
BIOS lock appears to be disabled in the BIOS you sent.
BIOS lock, located at position 0x17 in PchSetup.
Check this location with ru.exe, 01→00. If it is already 00 then you may need a sop8 programmer to refresh.
I tried with GRUB first:
“https://drive.google.com/file/d/1uM5B0vaiARLDlcIeR0VZ87631RB_ZFOV/view?usp=sharing”
This is RU.efi:
“https://drive.google.com/file/d/1iiYtNwqyyNxT9f9ZFo9zFlXhNqL3M_UM/view?usp=sharing” it seems neither PchSetup or cpuSetup exit or I’m doing something wrong.
Edit: I updated GRUB to latest version and tried setting “Me FW Image Re-Flash” from the guide to 0x01. This is the result:
“https://drive.google.com/file/d/1byzARqhmvIxPmN94clGzpGeQ5jq5m4VK/view?usp=sharing”
The first command gave an error but the second one seemed to change it but it got reset to the original value?
Blockquote GRUB：
“ 5.jpeg - Google Drive ”
Maybe it’s 0x1 (not 0x01?)
Blockquote This is RU.efi:
“6.jpeg - Google Drive” it seems neither PchSetup or cpuSetup exit or I’m doing something wrong.
yes it goes into the wrong place 。Sorry for so long, I have forgotten.
So I found one, the lock is at pchsetup (0x17)
It worked!!
The problem with RU.efi was the version I used. I downloaded an older version and the all UEFI variables names showed up. From there I found PchSetup changed the value of 0x17 from 0x1 to 0x0, saved it and then rebooted.
On windows I flashed the rom you sent me successfully.
Lastly I went to BIOS and all the settings showed up.
Thank you very much for your help.
