Tivo PROM Modification Question

Hello everyone,

I'm new to the DVR community so if you could bare with me, I'd really appreciate it. I've been from a number of people that it is not possible to do a PROM modification on a Tivo Series 4, but then again, I've also heard from some that it is possible. I really dont know what to believe! Anyone know which is true?

Many Thanks,

Robert

That's a forbidden topic on this forum. There is another Tivo forum that discusses such matters but you will have to search for it because it can't be mentioned here.

I think it is safe to mention it is impossible. Indeed, on an S4, the chain of trust is not merely coded on a PROM. It is also encrypted and coded into the CPU itself.

To find the site which can't be mentioned here and learn to which models the forbidden topic can be applied and to which ones it can't, google for "omikron prom day".

First result should be a link to DDB.
