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
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.
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?
I send you all of them, I can’t seem to find it.
I think it’s device 1F, function 5. Could you show it to me?
Thanks. Device ID on the summary screen confirms that it’s the SPI controller.
It’s a step futher. Now we know what blocks writing operations, at least. This topic helped much to acquire the problem. Next, gotta find out which way to change the value on offset 0xDC.
/// PCH BIOS Spec Flash Security Recommendation
BIOS needs to enable the BIOS Lock Enable (BLE) feature of the PCH by setting SPI/eSPI/LPC PCI offset DCh[1].
When this bit is set, attempts to write the Write Protect Disable (WPD) offset DCh[0] in PCH will cause a SMI which will allow the BIOS to verify that the write is from a valid source. When this bit (BLE) is set BIOS Lock Enable feature, EISS is locked down.
BIOS needs to enable the “Enable in SMM.STS” (EISS) feature of the PCH by setting SPI PCI offset DCh[5].
When this bit is set, the BIOS region is not writable until SMM sets the InSMM.STS bit, to ensure BIOS can only be modified from SMM.
But I not sure what to do with the other bits, reset or leave as is. Will let you know when I come up with something.

Sure, Thanks for the help 
Thus bit 0 has to be set, bits 1 and 5 cleared. Value AAh become 89h. BIOS Control (BIOS_SPI_BC) – Offset dc - 1.2 - ID:615146 | Intel® 400 Series Chipset On-Package Platform Controller Hub
But here’s the catch… bit 1 can’t be cleared until the “PLTRST#” (total reset) event is occured. And this bit doesn’t allow to clear bit 5.
The main question is how to perform the total reset without the laptop being shut down? If the laptop is restarted, the BIOS will lock itself again. Sad to admit, but the answer is nohow. The BIOS region is not writable until the CPU enters the SMM state, which occurs when official update starts.
