I know this is an old post, but I'm in a similar place. Upgraded to Commercial, registered product, and flash still fails. Here is what I see:

Status shows a green check, so I selected Test for the first time.

It ran through Simulate ECM memory erase
Then Simulate reflash and 2K of 224K
Reflash failed ... aborting
Total time 00:11
Data compressed 29.2%
Clear emission related DICs
FSP interface okay
Auto detect PCM
PCM not detected


Help!
