RSA and BoxKey extraction

Hello, I'm new to this forum but I've been reading a lot of these topics on the internet.

I've bought a Vu+ and installed OsCam Ymod. I could use clines to watch M*vi$tar+ channels (from Spain), but now I've paid a white card. I've received the original cisco C20 to use it, but I prefer to see my channels from Vu+ so I can interact automatically with my device.

I've tried to extract RSA and Box Key from the C20 to use them in the Oscam Ymod, but I've found that the jtag seems to be turned off and I can't access the keys. Could anyone help me to get those keys?
