on windows 10 found i needed to install the latest hx edit in order for windows to detect the helix again after the OK prompt on the firmware update now running the update again
would recommend to others backup with hxedit old version , then update hxedit ( which grabs the new line6 updater ) and then run the updater this should then allow the update to complete ok which mine does now seem to have and is now updating.
I had waited for ages previously and then turned off the helix and closed the updater and got stuck in boot mode , the fix was downloading the new hxedit which downloads new windows 10 usb drivers
