New XBox 360 Downgrade hack

[Paul] let me know about a new way to get a hacked kernel on a XBox 360. A new timing attack will soon allow you to install an older kernel with without having the CPU key which was the catch 22 situation before. The proof of concept ressurected a bricked XBox by doing some interesting things to one of the NAND (memory) blocks on the machine.
Great news for the homebrew/hacking scene!

    Surely you mean without the key?

    Looks like the advent of proper x360 homebrew, awesome!

    I love seeing people reverse engineer consoles like this. I wonder what the xbox360 engineers think… its gotta be amusing to see how people break into something you’ve designed to keep people out :)
