Nothing to disagree with all at. However, when I jumped into this thread, the inquiry was about "The Chip With The Lifetime Information On It". Technically there is no such thing, and I never said so (my bad). There is only a PROM (or flash chip), which didn't contain the TSN before the Premiere, and a "crypto" chip. A lot of things became more integrated along the way, and more security and validation was incorporated. Then there's the matter of the integration becoming part of a non-user swappable SOC, which is BGA mounted to the board, surface mount (with all Premieres). So, to make up for me not being clear, it's the TSN that is the key to TiVo's servers associating it as a Lifetime unit, and affording it that status, AFTER all the validation internally, and a recent connection to the TiVo Service (externally). The is nothing actually inside ANY TiVo that *makes* it lifetime, only the TSN, which must be both internally and externally validated, then the unit is afforded it's status, remotely. This validation expires, just like you say, and has to be re-affirmed by a Service Connection. The only legit way to transfer LT service, is either by a rare deal being made by TiVo, which is at their discretion, and is not free, if permitted. To illegitimately transfer the status would require internal mods/hacks, to make the TiVo Service believe a non LT unit is LT. I've never heard of any success story with a Premiere. To say any more, on what I know, about how to do this to pre-Premiere models, would violate the rules of *these* forums.
