Got mine yesterday, freezes all the time. Firmware update was a nightmare, but somehow i got it updated. Now the software jam 2-5 min. after i've turned it on. Apparently there's a lot of bad units, so this will go back again since it's unreliable. I've followed these steps with no effect, beside the Line 6 firmware update recommendation. As i remember it came with firmware 2.65 and it was working fine. Played around 2 hours with no issues.
