I tried upgrading my line 6 helix which was on 2.20 to the 2.30 firmware. I followed the instructions, installed HX edit, backed up then used Line6 updater to install firmware. Progress went OK, it started to install the firmware but then failed with "Firmware Update Failed. An error has occurred please try again" on the Line 6 Updater application.
I then followed the instructions about the USB and tried again - same problem.
I then followed the instructions about button 9+10 and tried again - same problem.
I then followed the instructions about button 6+12 and tried again - same problem.
I then tried using manually downloaded firmware rather than letting line6 updater download the firmware - same problem.
I am using Mac OS X 10.12.6
When I reboot helix now there is ":0" in the top left. Firmware version 2.30 does come up but then it goes in to "Boot Failure. Entered update mode!"
Helix is unusable for me now.
Does anybody have any ideas how to fix this please?
