So TivoHD running what seemed to be fine. Going to sell device, so figured I would do a "Clean & Delete". Go through menus select "Clean & Delete" Tivo says this will take over an hour. Then reboots. Tivo has not come up since. I have since run kickstart 54. Passed all tests. Tried 56, and even though it is connected to ethernet cable right to a modem, and the cable is live with dhcp, it says bad connection. Tried kickstart 52, and the tivo just stays on "Alomost There" screen. Does not get to "Install screen". Tried 57. That went to "Almost There"screen, then rebooted about 2 mins later. Still no boot. Ideas?
