Just to close the loop on this topic, I engaged both Line6 and Sweetwater (where I bought it) tech support on this and neither was able to solve the problem. I am working with Sweetwater on an exchange.

Thanks for the input on this datacommando. I tried the power on, no USB connection, with switch 2 + 3 held down. The Stomp comes up just as it did before with the additional message "Will reset Globals, Presets, IRs..." but does nothing after that. I also noticed that after the FW is updated, the Updater screen still says firmware version not available. Wonder if there is some final check or handshake that is missing. I've opened a support ticket.

OK. I have tried this on multiple computers now. A MacBook Pro, an HP laptop (Windows 10), and a Dell Inspiron PC (Windows 10). The results below were on the Dell PC with the USB cable plugged into a port on the back of the PC (direct motherboard connection hopefully). I followed your directions for uninstalling all Line6 SW and drivers then downloaded the latest HX Edit, Firmware 3.01, and the Line6 Updater 1.19. When I power on with "Page >" held down, the Line 6 Updater screen looks like this... I selected HX Stomp Unkown version then selected the version 3.01 Firmware previously downloaded (offline mode). The update progresses ... And completes with the process with the following screen... The Stomp now looks like this and I am stuck. The Stomp never resets and is not recognized via USB unless I reboot with "Page >" again (which takes me back to the top).

I too am stuck at the same point with the HX Stomp firmware upgrade. Received the unit with 2.65 and tried to update to 3.01 with the latest HX Edit (per instructions on the site). The firmware update was successful but the Stomp never started the rebuild preset step. It is stuck at the intro screen showing the current firmware release and is not recognized over USB (HX Edit shows no device connected). I have tried all of the advice listed in this thread with no success. I've tried with multiple cables, multiple USB ports, on Windows, on Mac, even different versions of firmware and they all end up at the same place. Any other ideas or am I headed toward a support ticket? Thanks.
