Seventhson: I successfully changed the DVD key and region code of a 360. So it's all confirmed. All I did towards this was to reverse the plaintext KV (Key Vault) signature to figure out how to modify and resign the KV contents. And even this work was built on the efforts of other hackers. For example, I didn't locate the region code in the KV and a lot of the SHA1 and RC4 encryption code was reversed and documented by others way before I started looking at it. *If* the region code tests are successful, then the following people contributed *much more* to this achievement than me. Takires, TheSpecialist, Robinsod, tmbinc.
