After I-don't-know-how-many tries, the reset procedure finally worked, so I'm back up and running normally. I've run into this before where some specified procedure doesn't work the first time, or the second time, but out of a lack of an alternative (I like to call it persistence), I keep trying it and it finally works. And I never know why. It wasn't the procedure or it would have worked the first time. So it must have been the procedure PLUS some additional, unknowable condition. Most troubling when I can't put my finger on what actually was the cure so I can repeat it the next time. After all, this is science, right? Anyway, if your attempts to reset don't work the first time, keep trying.
