In short the entire encryption is based on the cpu key... So how do you expect that you could decrypt it without this key...

You could try bruteforcing it... Let us know when the bruteforce process is done (in a year or 500)

So I'm very sorry to tell you this, but you CAN NOT get your dvd key when you have the summer update.

My advise would be to get it out of the dvd drive (if you haven't erased it already) else the only thing you're box is worth is a nice dvd player Wink

Iv'e been messing around with a couple of keyvaults with known cpu keys. im in the same boat as you here a console and no drive key or cpu..8955 Roll Eyes

360 Flash Tool 0.91
(Insert cpu key as dvd key)                                  (Self Encrypted/Decrypted CPU Key?)
CPU D2250EA2C6197597DE489DEA379CA098 <> CPUDVD B432B68FB8FF96A1BBBB13EB4A4721B2

(Decrypted DVD)                                                (Encrypted DVD)
DVD 470ABA0C5CEE4EF25314CF7F5336FA25 <> DVD 211D02212208ADC436E7417E2EED7B0F

Whats interesting is that the decrypted/encrypted keys work viceversa. the nand is a lock and i dont have a key all i know about my 8955 image is this

00000000000000000000000000000000 CPU KEY
00000000000000000000000000000000 DVD KEY
