I am one of those that things didn't go so well. I made sure that I followed the directions exactly, but the update failed and after many many tries using all of the different combinations of boot options, trying a different computer, different usb ports, different usb cable, trying to revert back to a previous version, my helix was still bricked. After opening a support ticket with Line 6, it was determined that I would have to send it in for repair. Since I bought it at Sweetwater, I will go that route for returning the unit. Man, I was really looking forward to trying out the new amps, but that will have to wait. Actually I have had issues updating in the past, but was always able to get the update to install. Still, I am very pleased with my helix. Sometimes things just go wrong. My biggest mistake was trying to update the day before Thanksgiving. I am still slapping myself over that decision. :rolleyes:
