and at the moment, xboxhacker.net has dumped the hypervisor, and examining it for it's own vulnerabilities so that they may find a 'universal' exploit that works with all xbox 360 kernals, that is, until m$ decides to update those too. but did m$ really blow efuses so that you cannot downgrade your kernal? and if just about everything can be updated(or reflashed) by microsoft, once we find a vulnerability(a good solid one, that requires a game, and perhaps only a Burnt CD-R) we can begin to make kernal or dash replacement chips, and work on some Bios loaders(Pheonix, nkpatcher?) which will eventually lead us to ultimate modding on the xbox 360
