We're sure you'll have a great experience with your Helix. As with anything, be sure to regularly back up your presets, and in the event anything unexpected happens while using your Helix, please perform one or more of the steps below.   If your Helix ends up in a bad state due to a failed firmware update, first perform a factory reset by holding footswitches 9+10 (Helix/LT) or encoders 5+6 (Rack) during boot up. Then reboot and enter update mode by holding down footswitches 6+12 (Helix/LT) or encoders 1+6 (Rack) Make sure to try this out on multiple computers in case of poor USB connections.       Helix Floorboard/LT   1.
