Xbox 360 Reset Hack Yields Unsigned Code Execution
walshy007 writes "A new exploit has been shown which allows unsigned code execution on the Xbox 360 for all current models. It functions by pulsing the reset pin at a critical time during the checksumming/crypto boot process.
The exploit enables the running of Xell, a boot loader which facilitates the running of Linux, amongst other programs."
Because its your hardware, and you should have the right to do so, whether or not you have a reason to at the moment. It's about preserving that right, which seems to be going away on more and more devices over time.
It does! Xell spits out the CPU key and the DVD key at the boot console. Just have a digital camera handy!
