Hello, guys!

I'm having trouble modding the bios on this laptop. I've managed to flash a modded one successfully, but it doesn't show any changes made with AMIBCP. The bios has some duplicated tabs (eg. "Advanced" and "Boot" tabs) which is a bit confusing.

My main goal is to unlock CPU Power Management (or similar) in order to undervolt the CPU and GPU, which is currently done via Intel XTU upon system startup.

Bios file can be found here (X510UAR version 309):

https://www.asus.com/supportonly/F510UA/HelpDesk_BIOS/

Any help will be appreciated, thanks.

@noreplyse - Please check main BIOS page and get ME FW version, if not found there check in large window of HWINFo64 motherboard section and find ME Firmware version, let me know. If this is AMD CPU system, never mind all that, and let me know.

Hi @Lost_N_BIOS

My system's ME Firmware version is 11.8 b3390 according to HWinfo, which is the same version of FPTw I used to flash the modded bios. If it is needed for any reason, my CPU is an Intel i5 8250U.

@noreplyse - OK, great, you've already flashed a modified BIOS via FPT. That's where I was heading to help you do

Please test all three of these BIOS, let me know if any give you secondary Advanced menu. This is only a root menu unlock test, if it appears but is empty that's OK and maybe expected, we can fix. This only test to see which way of these methods, if any, work to enable the menus'
Please also continue testing, if one BIOS works and shows both advanced, still try the rest, I need report back on all three please and thanks.

If we cannot get it, you can change with AMIBCP the default value, since you already know what you want to use from using XTU, then that will be the applied settings.

Thank you @Lost_N_BIOS for modding the bios so fast.

I've tested all three of them, but none of them showed any change (apart from overwriting the SN).

About modifying the values with AMIBCP, I wanted to do it in the bios so I could edit and bench the system faster, apart from being able to edit other options and settings.

I've also tried to enable the Chipset tab, but I couldn't make it visible either.

Sorry about the serial @noreplyse - I didn't think to have you send a FPT dump, hopefully you have one you can use to restore serial/UUID etc with
Looks like I will have to look at this in assembly when time permits, all the usual easier methods did not work. I can't make any promises since I am not great at finding things in assembly, but I will try once I have time (really behind here, so may take a few days)

Oh, sorry I didn't mention that I had a backup file. I've flashed it and the SN was restored :)

I've just downgraded to BIOS v308 because v309 has compatibility issues with macOS, so I will be using that one instead. Also, I will try to modify some default voltage values with AMIBCP in order to run the cpu cooler, though I will not set aggressive values.

As for modding the bios in assembly, I really appreciate it, but if you are busy don't worry, there is no rush :)

@noreplyse - It's more about if I can find and fix in assembly, I am not good at assembly but some things I can figure out, so that is why it takes me a long time (Plus I need to catch up first).
So it's no problem, but will have to wait until I can get in there.

@noreplyse - Bumping this up for myself and you, I think I know how to unlock now and will be working on this for you in next day or so!

Hi,
to modifier this bios and unlock hidden menus,follow these instructions.
Unlock-Chipset-tab-in-ASUS
the protection in AMITSE is the same as my PC... clear ID at 8C4F3 and 8C503, change the menus at 11E2F0 and 143C10.

Yes, I know @fv1862 - thanks! That is why I bumped this thread, going to do this users BIOS now and another one similar in other thread that reminded me about this thread (I forgot, sorry @noreplyse ) - [BIOS Modding Request] ASUS VivoBook S510UF/X510UF

* Edit @noreplyse - Since these laptops do not have USB Flashback, modified BIOS will be flashed easiest via FPT, and for this I need a FPT backup first from you in order to keep all your board details in the BIOS (Serial, UUID, DTS Key etc)
Please check BIOS main page for ME FW version, or if not shown there download [url=]HWINFO64[/url] and on the main large window, on the left side expand the motherboard section and find ME then look for ME Firmware Version.
Once you've found ME FW version, go to this thread in section "C" and download the ME System Tools package that matches your main ME FW version number
Intel Management Engine: Drivers, Firmware & System Tools

Inside that package you will find Flash Programming Tool folder, and inside that a windows or Win or Win32 folder, select that Win/Win32 folder and hold shift, then press right click and choose open command windows here (Not power shell)
Then type the following command, zip the created file and send to me for modification
FPTw.exe -bios -d biosreg.bin

@fv1862 and @Lost_N_BIOS

Thank you both for helping. I will try it right away.

In the meantime, @Lost_N_BIOS , do you know how to use the BT utility? My keyboard lost its backlight and I can't use the BT Asus utility: when I try to execute the command bt -c CNFG /W DD 7C it always fails saying that there is "no support EXTF function". I know this setting must be somewhere in the NVRAM config (as I'm trying to edit the config block) but I can't find it with other utilities (as UEFITool).

PS: I'm sorry for replying a month later, I was away for a couple of weeks and totally forgot about this thread :)

EDIT:
Bios dump (v308) with FPT (ME v11) uploaded.

@ noreplyse

For backlight extract the rar and put the 2 files on BOOTABLE USB,
run FIXMYKB.BAT, you receive an error (it's OK),
then restart, and light should resume.

@fv1862

Thank you for the file, but I get the same error message and nothing happens.

The error I get is the one on the attached image.

Thanks

How to format the USB DRIVE ?
Try in FAT32, DISABLE SECURE BOOT and ENABLE CSM in bios.
