So today, out of the blue, I came home, and my Tivo Premiere was at "Please wait, just a few minutes more". It then rebooted, and went back to the startup screen, then please wait just a few minutes more again. It did this at least 3 more times, at which I tried the kickstart codes. When I hit Pause, the lights stop flickering, and then they light when I press each number - I tried all the software codes, 51, 52, etc. After entering the numbers, the yellow and green lights flash back and forth, then that appears to be it. Still it keeps rebooting. Any other suggestions on what to try? Thanks!
