are the backup kernel programed or hardcoded
in some chip on the 360?
my guess would be hardcoded, but we probably wont know until the second kernel update via Live
If its hardcoded the next question, is it replacable
doubtful, remember all these critical components on the processor itself, would be next to impossible for anyone to remove and replace components
and if its programmed, can we reprogram it ?
if this is the case then yeah, im sure we can figure a way to program it, however my worries still lie with hypervisor, if we program both the backup and the primary kernel they will both fail hash and signature checks, so the hypervisor will just throw the whole system into a reflashing loop and you wont be able to do anything with the system
One other question, the backup
kernal in the box, is it encrypted, compressed, both or plain code
it will definately be encrypted, i would say not compressed though, theres not much to compress on it, and its likely so small they wouldnt risk corruption just say to a couple kb
