I recently had the hdd die in my series 2 Tivo and downloaded Instantcake and installed on a drive I had in an external hdd last night. I noticed the software version of the Tivo is 7.2.blah so I forced the Tivo to connect, but my software version is still the same. Will my new IC Tivo not receive software update anymore? I was under the impression that the box would function just like it use to, along with software updates. Am I stuck at 7.2 forever?
