At this point, I'm really looking for any custom DELL tech support utilities to diagnose or log the TPM update utility progress. The message "Update Failed, Blocked by TPM FW Policy" isn't detailed enough.
I'm beginning to believe I may have a TPM chip problem, such as the chip thinks it's already been flashed the max amount of times. I'd like to find out what the Self Test values mean: {255, 1, 2, 5...}
Yes I've tried about every OS / BIOS / HW / TPM setting combinations and system resets that I can think of. I'm sort of an IT specialist too, so I'm well versed in DELL PC's and have successfully updated other T3620's at my workplace. (we have hundreds).
I've even tried stepping back the BIOS FW from 2.19.0 all the way back to 2.3.0 and it made no difference. My BIOS has only ever shown TPM 1.2 and not the TPM 1.2/2.0 that some of the documentation references.
Something else of interest. DELL has already stated it won't have full driver support for the T3620 and Windows 11.
I tested a Windows 11 installation, and although the systems seemed to respond normally, these are the only devices that the installation didn't find drivers for.

The replacement motherboard came tonight. 0MWYPT revision A02.
It had BIOS revision 2.12.0 installed with TPM 1.2 v5.81.2.1
The TPM 2.0 v1.3.2.8 flash update was successful !!!!!!!!!!
A couple things I noticed. This replacement board BIOS had a "Trusted Execution" option under the Virtualization category that my prior BIOS did not, but it wasn't checked. This system also reports the TPM manufacturer as NTC.
