I have very reliable sources that explain to me that with the use of an XDk and the Cpu key you can sign and create your own Packages. Now knowing now that the CpU key is used for this maybe we can gat some progress on this

if you got the cpu key you can downgrade anyway  so what effort should that bring ? what we really need is a good way to retrieve the cpu key. |

as far as I know it's NOT just a matter of the cpu key, but you also need MS' 2048 bit signature key.

If this is true than maybe it is possible to boot linux directly by signing some loader... Of course the problem remains how to get the cpu key  |

Which is widely available on (I believe) any dev kit. I was told that if I wanted my content package signed I would just need to give him my CPU key. |

uhm.. I have a feeling you don't really know what you are talking about.
the CPU key is unique for every 360.

even then, you are completely wrong. the signature key is not available to devs, or even 99.9% of the people at MS. that key would allow anyone to sign ANY code, effectively allowing you to run homebrew and pirated games without any modification whatsoever.

using the cpu key would mean the data would only work on your console if that were the case. Dugg down.

This is a strech for me....but what about someone dumping the devkit kernel and flashing it to a retail 360 and seeing how that goes? or would the kernel be linked to the hardware of that perticular box?

if you can manage to squeeze a 64 MB flash into a 16 MB chip, sure, go ahead.
and as always, the kernel is linked to the specific hardware.

Other than the 64MB nand flash how much other hardware is different?

None, we tested a Samsung 32MB flash and that worked fine so there's no reason to think the 360 is checking the Mfr/Device ID. The comms protocol is the same for 16,32 & 64MB so it should be a drop in replacement. You could even steal the flash chip from a 360 memory card (or usb thumb drive) Now all you have do is obtain a dev console dump, patch it to work with your hardware and let us all know how |

ok, what he was reffering to is at best out of reach for the majority. However it is a valid point and something which kickstarted the xbox - obtaining a decrypted dump from a devkit. ok this time hd is different and nand dump is considerably larger. Im fairly confident devkit dumps are out there somewhere and that the same level of analysis that some on here are applying to the retail kernel, hv etc is being done (perhaps not quite as much in the public eye as here)
