I have a brand new Helix. Before ever playing a note, I tried to update the firmware to 2.92. Update failed, and now the unit will not boot up. It just gives error statement "Boot Failure. Entered Update Mode!" and it is stuck there. I don't know what to do. I've tried everything I could find online, like pressing F9-F10 when it boots, but nothing. Helix Edit no longer recognizes Helix as connected to computer. Can anybody help? I guess I'm too new to this stuff.
