New Helix updates available in Helix Posted November 1, 2015 No loss of power, it did said "could not complete update, please power off and try again" (not those exact words). Now, the problem is that since it doesn't boot anymore (it gets stuck at error -28) the USB is no longer recognized and therefore I can't do anything firmware wise, at least through the Line 6 updater :( I tried the 9+10 switches on boot, it says it will "reset Globals and restore stock Presets, Setlists and IRs..." but the ":(-28" still shows in the left top corner and it has been sitting there for the last 30 minutes. Is there a secret Kung Fu Grip that will make the Helix go back to v1.0 or anything that I can do before returning it? Helix gurus help me, you're my only hope! Right now it's the most expensive door stop I ever bought... I'm so glad I waited after my Halloween gig before trying to update the firmware! You might also try holding down the 7 & 8 footswitches (two switches on the far left bottom row) while powering up, release the footswitches after you hopefully get the firmware message on the screen. Good luck!
