Yesterday evening our S3 OLED went into an endless reboot cycle. It gives us the "Wait, Powering Up" screen for a couple minutes, and then boots again, with same result. I tried to do a kickstart, but it just reboots to the same cycle after I enter the kickstart code. Does this simply mean that the hard drive is completely dead? Or is it just mostly dead, with a chance of being saved (would hate to lose all those shows)? Is there maybe something else going on with the tivo itself? The unit has a lifetime sub, and quite honestly I like it much better than our premiere, so I'd like to save it. If it is simply a case of replacing the hard drive and all will be well, does anyone have a disk image for model 648250B, and is it difficult to do? If it is not difficult, I'd rather do it myself to save some cost. Thank you.
