I'm having problems with my TiVo HD. I started having guide updating issues a few months ago. Restarting the TiVo normally fixed if for 2 weeks. Last week I got the SO3 error. Trying to fix it I tried to run Guided Setup again thinking it would start over, how wrong I was. I'm now stuck at the guided setup. Tech support has no helpful information other than to keep trying to connect to TiVo at less busy hours. I've tried the kickstart 54, all hard drives passed, I've tried the kickstart 57 no issues. I've tried changing my zip code, no luck. I've changed to antennae instead of cable, no luck. I've tried dial up, wireless usb, and back to ethernet, no luck. The TiVo keeps getting stuck on the loading part of the connection process. Any clues on how to get out of this loop?
