My Helix LT has been doing the same exact thing as stated here since I bought it used. All footswitches and pedals become unresponsive randomly and I have to power off and back on to temporarily bypass the issue. I bought it with the 3.15 update and attempted to factory reset and restore from a backup several times with no luck. When 3.51 came out I was hopeful that the issue would be fixed, but unfortunately it has not. If it's a simple fix I would obviously prefer to do it myself rather than send it in and pay a bench fee and whatever other fees there might be. tonawandajon, can you confirm that the issue was fixed after you sent it in? If so, did they ever happen to give any insight as to what the problem was?
