I broke Nagra 3. Hammer and chisel on the smart card, that sorted it.
On a more serious note Nagra 3 has stood up for a while now, in numerous countries. Nagra 1 and 2 were broken elsewhere, these same places haven't managed it with Nagra 3 as yet. There is absolutely no reason at all to think that we in the UK are magically gifted or skilled and will be able to bring down Nagra 3 in weeks when they couldn't given years. Why do you think the dodgy box manufacturers and sellers here are 'diversifying' into Freesat
Quote from someone with a clue:
In terms of physical protection, the Rom180 is very anologous to the NDS line of chips. I really doubt anyone is going to be getting into them anytime soon. After 2 years the Spanish (where most of the Nagra hacking is actually done) still haven't got very far with N3 !
