I have the same as above. Restarted but Helix is no longer recognized. Helix continues to show "Boot Failure, entered Update Model" and editor does not see the helix.
Tried various iterations of turning stuff on and off: no effect.
Tried moving off of my powered USB hub (only mouse and helix on computer): No effect on Helix or update, successful in raising my concern I really screwed this up.
Updater was updated prior to starting the update (running 1.17)
Backup completed before update.
