Even if there is a private HD fix. I suspect extracting the necessary info from the box is way beyond most people.
at first who told you about this is icam issue ? icam use the chipset to do some things
yes there is private hd fix for long time but not for sale even the man who did it keept it only for its private customers
extracting the necessary info from the box is way beyond most people - not exactly and is depend on something
btw i think the most part of sky uk *** firmware is encrypted by cpu on almost all receivers like amstrad samsung pace and multiroom stb but the hack wasnt done by decrypting this firmware
you can decompress a part of it and find CFE also some vxworks parts but thats just a part to other most important part are not compressed and even nor encrypt with usuall alghoritm this is data keyed by cpu which is holding full camcrypt
well if you can dig with it then maybe we can talk about to do somet things later
