[REQUEST] CLEAR ME BIOS for rebrand of the ASUS H610M2 FPT

[hwdiags]

• Did you try to boot without your diagnostic device?

OMG, I try to boot without your diagnostic card. It has done… Damn. Learned

So, I still have a trouble that why MB can’t boot with diagnostic card is inserted?
I think the good backup bios has problem. I will borrow new good board to check and confirm here.

Thanks @lfb6

Thanks for the feedback- good to hear that it worked! From firmware side there wasn’t any reason for boot problems any longer.

When you clean the ME you remove the software TPM config residing in the ME. So- possibly- first start the ME looks for a hardware device before enabling the software TPM in the ME. Finding ‘something’ in the TPM- socket which might answer but not in the way ME is expecting- booting stops?

For learning… what kind of app you use to convert binary to xml, like your picture above? FIT?
Can I extract Me region from stock BIOS file by UEFI tool directly (because I see in UEFI Tool show detail section separately) then put it in FIT decompress folder to built ClearMe? How can you do that?

[lfb6]

All FIT versions save their settings as xml- file. How did you reload your settings when cleaning an ME if not from the saved xml- file?

I use UEFIToolNE for extracting since it displys the strucure much better (but no difference for a complete region)

To replace a region you have to use UEFITool 0.25 or 0.28:

You can’t use an extracted ME region in FIT, but replacing it in UEFITool is a lot easier. For your identical H610 boards you’d have to do the cleaning once and you could simply use the same cleaned ME region extracted from outimage (never booted / showing configured and not initialized in MEA) for all the boards.

Understood. Thanks @lfb6 at all

NVRAM (already reset to empty stock NVRAM in the second file I attached earlier - “2.bin”),

Last question that how to reset to empty stock?

[lfb6]

Use UEFIToolNE for structure and adresses und UEFITool 0.25 or 0.28 for replacing an EFI volume.

For this kind of bios region with two NVRAM volumes: Fille the space for the second volume completely with “FF”, here from 0x530000 to 0x55FFFF (including)

For the first NVRAM volume:

• Fill the space between first entry after defaults (including it) to the last line of the guid store with FF- last line of GUID store should correspond to the GUID of the defaults volume.
  OR
• Extract the NVRAM volume of a stock bios with UEFITOOL or UEFITOOLNE “extract as is”, save it, open the bios dump you’re working on in UEFITool 0.25/0.28 and “replaces as is” the first NVRAM volume with the one you extracted and saved from a stock bios.
