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.
1. Holding footswitch 5+6 on boot restores Global parameters
2. Holding footswitch 7+8 on boot restores presets and setlists ”THIS WILL OVERWRITE ALL USER PRESETS AND SETLISTS
3. Holding footswitch 8+9 on boot restores presets, setlists, and IRs ”THIS WILL OVERWRITE ALL USER PRESETS AND SETLISTS
4. Holding footswitch 9+10 on boot restores presets, setlists, globals and IRs (restores factory bundle) "THIS WILL OVERWRITE ALL USER PRESETS AND SETLISTS
5. Holding footswitch 10+11 on boot will rebuild your presets in the latest loaded firmware
6. Helix can now restore by clearing only the current preset instead of wiping out all presets. While holding footswitches 11 + 12
7. Helix can now, after firmware 1.06.5, enter update mode manually by holding footswitches 6 + 12
Since the rack doesn't have footswitches, you'll instead hold down a combination of the 6 encoders that are below the main LCD screen as you're booting up.
