Xbox360 Hacked

Xbox 360 Hacked

A Hacker under the nickname SeventhSon has discovered a method to alter both the DVD key and game region code on Microsoft's Xbox 360, at least for the Hypervisor exploitable 4532 and 4548 kernels. A great part of this hack also involves desoldering your Xbox flash chip something that only the technologically handy will try.

I successfully changed the DVD key and region code of a 360. So it's all confirmed.

As for landmarks and interweb fame. All I did towards this was to reverse the plaintext KV 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.

The following assumes you have the correct 1BL key and CPU key set in the flashtool.
1. Dump the NAND from the US 360 (528-bytes-per-page)
2. Open in the latest flashtool (v0.8) and click [extract]
3. Edit extracted KV.bin and change 16-bits at offset 0xB8 from 0x00FF to 0x02FE
4. Open in flashtool and click [patch], check the "patch keyvault" box and select the KV.bin modified in step 3
5. Click [OK] and choose output file
6. Flash output image back to the NAND of the US 360
7. Try an EU game or two.

No! The games are region locked, ie a US/NTSC game will not run in a PAL/Europe system. This hack allows you to play any region of game in any console ;) (obviously the 360 has to be flashed with the Xtreme firmware 1st)

I was gonna ask the same thing. Im a little bit somewhat hesitant to do anything to my 360 or for that matter, PS3, to allow burnt games or other regional games to be played on them. Unless you can read japanese and german and all that stuff, no since in playing PAL games, except perhaps if England gets one we dont
