It turns out the fact that I got a successful update was, perhaps, a fluke. Something is amiss with the TT3 now and it keeps losing its mind. I’m thinking it’s not stray RF since it still works fine when connected to the FT-8800. Perhaps something came loose in the cable, though, and that is throwing it off. Regardless, I’m back off the air until I can figure out the problem and come up with a solution. What a rollercoaster. :-/
