Now we just have to find a way to use the Edge Exploit to dump the encryption key for the nand, so the real fun can begin. ;)

Yeah,it is important to bear in mind that all Nand Files are encrypted. Probably we have some options. First we attack directly the Platform Security Processor (the PSP is inside the Xbox One CPU and monitored all encryption and decryption operations of the KeyVault and the PSP stored different Keys) to get important keys for decryption, or we can Hack the Host OS (if we can escape from VM), to get directly access to the PSP via Software like Xell. If we have the decryption Keys, we can decrypt all dumped Nand Files from each Xbox One and can do nasty things.
