This resolved the issue for me. Initially the updater was showing no progress bar, and the Helix display showed "Update message server Started". After moving to my PC rearUSB 2.0 connections, the "Installing Firmware Update" message appeared in the installer with a progress bar that slowly but steadily completed the firmware update. I'm my case the upgrade from 3.11 to 3.15 took about 10 minutes.
