Thank you for posting this, and it sucks to see snarky replies instead of actual help.  Rapid preset changes is not the only way this occurs.  I also have the Floor and it happened even when I first turned it on (I bought the unit used thru a major online shop, and still had the protective film on the displays) and started clicking thru all the presets to get a taste of all the tones, moving on to the next after a few strums, maybe 2-5 seconds between changes at the fastest.  Then it would completely brick before I could get thru the first factory setlist.  Nothing would work.  Not a single button, knob, footswitch, even sending the sound to my headphones ... nothing until I powered down and back up.  After going thru this a few times, I guessed it was because I had overwhelmed it by cycling thru too many presets.  Wrong!
 
	 
 
	By that time, I found a couple fav presets I could practice a few songs with, switching once or twice during a song.  This worked fine for about 45min, then the whole unit bricked just as it had before.  After attempting this several times, I noticed it continued to occur near the 45min mark.  I had searched around the bug reports within the past month and saw a similar post that also hinted this was a known problem, bricking with normal use after a certain time window.  People suggested perhaps it was due to a corrupt preset and that reloading a backup or a factory reset could possibly work (which it did, at least temporarily, for that person).  I did a factory reset, and I still run into the same issue.  In fact, the only time I have played for longer than 45min on it without it bricking is by staying on the same preset.  After that time window, if I change the preset, it bricks.  Every time.
 
	 
 
	I sure hope they figure this one out, because I can't imagine playing live with this thing someday if it's going to cut out in the middle of a set.
