Turn off the Helix and close all line6/audio software. Reinstall HX Edit (2.92) - When you get to the options section of the install, leave them all checked. Start the Helix with FS6 and FS12 pressed (update mode) and start the update again.

Maybe you use different output settings for path 1 and 2 - multi for one path and a single output block(Xlr / 1/4, ...) for the other? Depending on the global settings this can lead to diffrences in the volume on headphones.

Sometimes I had the same problem after an update. What works for me: Uninstall all line6 stuff and reboot the computer. Then check in the Windows device manger for hidden devices and uninstall all unnecessary drivers from USB sticks and USB hard drives,... (To many loaded drivers can sometimes cause problems on a USB port) But don't delete any important system drivers! Reboot again and install HX Edit - When you get to the options section of the install, leave them all checked.

the confirmation may take a few hours/days (especially on weekend), if I remember correctly (...make sure the email doesn't go to spam folder)

" Boot Failure, Entered Update Mode! with the sine waves moving below it." - This may take a while(20 minutes) when you update from 2.3 to 2.9 Try theses steps if you still have problems: Turn off the Helix and close all line6/audio software. Uninstall all line 6 software and drivers and reboot. Reinstall the HX Edit package (2.92) - When you get to the options section of the install, leave them all checked. Start the Helix with FS6 and FS12 pressed (update mode) Start the LINE 6 Updater. (...don't use a USB-HUB, try annother USB-port if it still does not work use annother computer for the update)

I had problems updating my Helix Floor from 2.91 to 2.92 (I Have tried to update in HX Edit and with the Line6 Updater). After the backup there was always an error message and the Helix lost connection. I have uninstalled everything (HX Edit, all line 6 drivers). After a reboot I have installed the HX Edit 2.92 package again and I was able to finish the update. ...maybe it's a similar problem

You are right. Disconnect the Helix and reinstall HX Edit (when you get to the options section of the install, leave them all checked). I would also try annother port (sometimes the Helix is a little picky)

OK. ...maybe a bug or something

You don't need a battery, when you use the Helix Ethernet port. It's then powerd by the Helix. Do you use different presets for the Variax and regular guitar? Then maybe the output settings (if you use Multi or XLR, 1/4) could affect the headphone volume depending on the global headphones settings. If you use the same preset, there should be no difference, when the external FRFR volume is fine. " - PS when is 2.9 coming out? :-) " This year, ...maybe :)

This happen on all presets? Maybe something is wrong with the downloaded preset? Have you installed the lastest firmware? Have you checked your global settings>footswitches? Have you tried a reset? Holding footswitch 5+6 on boot restores Global parameters. Holding footswitch 9+10 on boot restores presets, setlists, globals and IRs - Don't forget to backup!!!

If a reset (Holding footswitch 9+10 on boot) or the update mode ( holding footswitches 6 + 12 ) does not work, then it is probably a hardware defect. :( I would open a support ticket.

"Make sure that you close HX Edit first. You can't have both applications running at the same time."(VirtualGuitars) If that does not work: Disconnect the Helix. Reinstall HX Edit 2.82 (and all included drivers) and try again. ... or try a different USB port

Have you tried reinstalling HX Edit? https://line6.com/support/topic/51796-issues-updating-to-282-helix-isnt-seen/
