For what it's worth, my Spider v 120 was stuck on the logo screen. I tried everything but nothing worked until I turned off amp and held the amp and fx buttons at the same time while turning on the amp. Surprisingly, the screen said ready for update, so I started the Line6 installer. Now the V 120 was now selectable, where it was not every other time I tried to access it from the installer. I selected the V 120 and then selected the update that was listed. After the update the amp works fine.
