In the description here you find information on firmware update for the Helix: http://line6.com/support/page/kb/_/effects-controllers/helix/how-to-update-the-helixs-firmware-r776. If I understand this info correctly, this means that I need a running internet connection for the update.
The problem is: There is no WiFi, nor any other internet connection in our band's rehearsal room whatsoever. And I'd hate to transport the helix more often than I have to, at least until I've got a flightcase for it.
So my question is: Is there a way to download the firmware file and install it offline?
