[Request] Gigabyte G5 KC Bios Unlock/ Mod

It’s hard to say because I don’t actually know what this program loaded for you. Can I have a picture?


@Sweet_Kitten

Although a different browser loaded successfully, your BIOS used the genuine one anyways.

Op LoadFromFS
SetupBrowser.efi
Op Exec
Op LoadFromFS
DisplayEngine.efi
Op Exec

Because their IDs are different, new didn’t replace the other one?

The process went in a strange way, not as I expected. So, nothing really useful appeared.

But it’s a step further! There will be a third archive. Be patient.

Naxxly~3.zip (412.9 KB)
2 more items should appear. Don’t know if they’d have own logo images.

Hello Sweet_Kitten, i backed up my bios using BACKUP_Tools20h2.exe.
My Device is Gigabyte G5 GD, i5-11400H, RTX3050, bios version is FB10.

Please help me unlock my bios, thank you.

Hello.
I offered the automatic solution to community not too long ago. It is still available. Post #224.
It is simple in usage as clicking start.

i tried “Gigabyte G5 (RTX 30 Series & Intel 11th Gen & Intel 12th Gen & 2023)_MOD.zip”
Opened START.bat, got error:
“Error 621: Unsupported hardware platform. HW: Tigerlake Platform. Supported HW: Cometlake Platform”
i ignore it and let it run, after a while it says:
“FAIL!!! Already patched or no applicable patterns found.”
i came back and read the discussion and found that @Naxxly have the same problem as me, so i tried to boot Naxxly~3.zip
i got to the boot options just like Naxxly:
G5 GD
G5 GD (list of something i don’t remember)
Device Manager
both boot option show the same:


My OS is Windows 11 update latest

BTW, i tried to run the bat in WinPE


probably just WinPE missing dependencies tho.

Form browser doesn’t seem to accept any other entry than EFI_IFR_GUID_OP. Values for this opcode are vendor specific. On top of that, I don’t know how to obtain them. Those boot options led you back to shell screen because no related forms were found.

Got to figure out a way to use the custom browser. I will stop working on idea of bootable app modding for a while.

No need to try the third app version anymore, @Naxxly. It’s a failure.

I suspect it crashed on file saving. Do you have some other WinPE?

Thanks for replying, unfortunately i do not have other WinPE. So i guess i will have to wait until you figure out how to proceed? Or if you’d like to interact in real time, i have Discord:
AugustinGamarra#2762 and you can Remote View or something like that. I’m usually available at 18:00 GMT+7

It’s unlikely to happen in the near future. Having an only smartphone as primary device remote view is not a good idea. The screen is too small.

I’d suggest to try entering the command from your last screenshot manually and see if UEFIPatch generate a modified file.
I’ll send you a Discord message what else could be done. This thread getting floody.

Hello, I’m sorry to resurrect an old post, I wanted to know if it’s possible to use this Mod for G5 KE 12500h rtx 3060. I tried to use it but it says “You ought to flash the Mod manually by some SPI prog. tool”. All good? Thanks in advance.

That’s right, for new Gigabyte laptops with 12 gen CPU, the script is only capable of generating a “MOD.bin” file.

Gigabyte G5 is a Clevo barebone device. And they don’t allow to install customized BIOS anymore. I think that some register of PCH (platform controller hub) blocks operations with SPI, if CPU is NOT in SMM state. There’s no solution to this yet, unless you’re willing to help.

Thanks for the answer, I have never modified any bios, so where I can I would gladly help.

I’d need only a little of info to say whether we have a chance or not.

First of all search for the PCH SPI Flash controller in Device manager. It may be named differently depending on the chipset.
PCH SPI
If it’s displayed there it’s great. Then download RWEverything and try finding the controller as one of PCI devices in RWE. If you do this miraculously, select it from the drop-down menu and make a screenshot for me.

The only thing named SPI controller I found is this:


I tried to open RWEverything but it says Driver cannot be loaded.

Ok, I disabled core isolation and set to zero a key in regedit and now it works, A windows 11 problem. Now I have a white page on RWE. What I have to do?

PCI

I send you all of them, I can’t seem to find it.
