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.
