Advertisements Tivo Spec: Tivo S3 with no cable cards, no external HD, uses cable and antenna and Tivo wireless card. I am wondering if anyone else is having the same issue. I have Tivo S3 for 2 years and it started happening 2 weeks ago. Tivo froze and started to reboot, remote is non responsive. I had to unplug the power and try to reboot it. It refused to reboot. So I purchased InstantCake and burn a new 750GB HD. It boots up fine and I was able to set it up and use it for a few more days then the same thing happens. I bought a brand new 1TB HD and used instantCake again. This time it only lasted 2 days and Tivo rebooted and could not finish reboot. Everything seems to be pointing to Tivo software update, because after using instantcake, Tivo boots up normal and everything works fine, but after a few days getting all the updates, issue comes right back. I have tried to instantcake 3 different HDs. I really doubt it's the problem with the HD. I really hope someone on this forum can help me, I am so frustrated! Thanks in advance!
