Hello everyone, I recently got a Galax H310M motherboard for an old i5 7600K CPU I had lying around since I knew that it works out of the box with all LGA 1151 CPUs (6-9th gen)
I enabled TPM initially and installed Windows 11 without any warnings or issues. However I found out that Sleep S3 state was not supported. So I tried cross flashing BIOSes from different boards (Colorful H310M, Soyo H310, MSI H310M). The colorful BIOS worked perfectly and I was able to get S3 sleep state supported as well. However I was not able to enable secure boot and Intel PTT.
Since then, I have rolled back to the original Galax BIOS but no matter what I do, Intel PTT/TPM is not working anymore. I have cleared CMOS, tried with ME 11.6 - 11.7 and no matter what, it does not work. I checked with MEInfo and PTT now shows enabled in ME but disabled in FPF.

Is there any way to get PTT working again in this case?

I have no idea how it happened but it was probably the chipset was still in manufacturing mode and one of the BIOSes I flashed must have disabled PTT in FPF. I am not sure if it has locked it yet. Any help is appreciated.

Hi. Yes that is correct. I was confused as well since my activity involved cross flashing as well.

Hello everyone, so I did some checking again and with MEInfo -verbose, I can see that manufacturing mode is enabled. So to my understanding, it should still be possible to make PTT enabled in FPF and then disable manufacturing mode thus committing the change.
However, I did try flashing a checked PTT enabled ME firmware with FPT followed by fptw64 -greset but no matter what, I have not been able to enable PTT in FPF.

I referred to this thread for the instructions:
Activate PTT in ME firmware (2)

I also followed the instructions in the ME Data initialization thread but that didn't work either. I did not lock manufacturing mode yet. Any help will be greatly appreciated.
@plutomaniac - Can you please help me out? Thanks in advance.
