No, it wasn't the downgrade, apparently it was the SAME version (.211). It just wouldn't take because I was doing it from CWM, not the Moto Recovery. Also, it was on the internal SD card. Moved it to the External SD, rebooted into Stock Recovery, flashed and it went off without a hitch. Thanks for the suggestion of possible cause though. :hail:
I don't think I've downloaded the downgrade zip yet. Haven't needed it since I didn't upgrade to .214. However when I saw the positive response to .215, and that it had Chrome built-in, I decided to take the plunge.
