The Custom Zune Firmware hack?

Could this be The Custom Zune Firmware Hack? Two guys from Zuney.net forum, ShaiLigum & Saulius, say they have done it: The first step was to downgrade the official Zune Firmware. But they also claim they are very close, if not already there, to load and boot a Custom Zune Firmware...


From their thread on Zuney.net :
Well, we're proud to say that Saulius and I have managed to downgrade the zunes firmware with nothing but a computer and a zune, and no problems at all!
no ZIFF cables needed, nothing.
safe to say, we believe that the first firmware mod is on its way, since we have nearly gotten the zune to transfer modded firmware onto itself.


[...] We managed to get two things:

1. Zune Certificate Authority
2. The Encryption Key

and we never tried to make our own firmware, we simply changed around the old one.
of course the 'sig check' will nullify this again, but the zune itself doesnt check for a sig, it uses a different method.
and there is really no need for a crack...our method is much much simpler than that.

[...] i double checked
theres more than one key
i got the thumbprint too


[...]the zune program checks for the exact file size of the file before sending it and booting it onto the zune. that is one of its ways of verification. if you can keep the file size proper, you are well on your way.
