Advertisements Hello, I'm trying to connect a Tivo Mini (A93000) to an existing network of Romaios (2) and Tivo Minis (2) - all on version 3 of the Tivo experience. This new Tivo Mini was purchased from eBay and is on v4. I deleted and reset everything on the Tivo Mini and now during Guided Setup, on the DVR selection screen it sees both Roamio boxes but both are grey out and have red circle error. When I select any of the DVRs, I'm presented with the C70 error. After spending 3 hrs on the phone with Tivo, they are saying the Mini "has been modified by a Cable company - NCTC/Mediacom" and it cannot be activated. Has anyone ever heard of this? Is there a way completely reset the box?
