I have this same kinda problem. I was trying to update to Firmware Version 2.11, but i got an "An error has ocurred. Please try again."
When i turn on Helix, its a Line 6 logo that flashes, and it says Helix Rack, when i got the floor model. Also there is this red symbol.
If i try to start it in Safe Mode (6+12), the flashing logo and rack icon is gone, but it still get the error message when i try to update.
Also i can NOT reset globals and delete presets, since this lollipop comes up.
Nothing i've read till now has worked, hope someone has a solution! Thanks :)
