Sky box Sky+ box hacks cracks chipped pirate etc

I have seen lots of requests and comments posted over the years about this topic. I hope the little knowledge I have on this subject will give you some idea of how complex it is and why it's pointless (as well as illegal) trying.
Sky and Sky + boxes made by all manufactures are based on similar chip sets and processors. It is in the best interests of manufacturers and suppliers not to provide access to schematics (circuit diagrams) and details of components so as not to give anyone the opportunity to hack Sky NDS encrypted systems.

The block diagram is of the ST Omega processor and shows the multiple functions it carries out. ST along with Conexant make the majority of chips for STB's and PVR's.

As the diagram shows there are a lot of devices running the processor which all play a part in decrypting the satellite data streams. Details on some of these devices and their function is pretty much non existent and seem only available to manufacturers and developers. Some data sheets on PIC.FLASH, and the SDRAM chips can be found on the Internet but without software, plus a good knowledge of coding and programming interfaces the hacking of them is next to impossible.

Limited success in turning a Sky+ box into a subscription free pvr seems to have been achieved on the following site  Sky+ pvr Hack

I've never tried or tested any of the processes involved on this website and they do seem a bit hit and miss.
In conclusion I think for the sake of saving yourself  £10 a month you may as well save up and get a freesat HD pvr. As for hacking Sky decoders it's never going to happen. The moment they get a sniff of a problem they have too many software variables which would render a large scale hack harmless.
