I just upgraded from 5.0.12 to 5.0.16C, and everything seemed OK until I noticed that the Z-Wave antenna had reset to internal instead of external.
When I tried to change it back to external, I got the attached Z-Wave error message, and when I checked the Z-Wave firmware information, I'm sure it was showing a Bootloader Version before the upgrade (I think it was 1.03, but now 0.00).
I tried power cycling a couple of times and reloading the 5.0.16C firmware again, but got the same results.
Any thoughts?
