I fixed the problem the other day and posted my solution in another post, but what I did was I closed hx edit and unplugged the usb from my helix and my computer. Then I turned on and off my helix , and plugged the usb back in. Then I launched the line 6 updater and selected my helix then updated it. However , it only showed me 2.92 instead of 3.0 but maybe it’ll show you 3.0
