Thanks for having a try.

You do have an affected panel, and if the system isn't freezing this shows that the updated firmware worked. The version you tested ( 0x0400003c ) is a little newer than I suggested ( 0x400003a ) but that's fine. The fix carries forward.

Good; you don't have PSR manually disabled.
