seriously, is it even possible?
that guy who created ixtreme has been saying that firmware is undetectable over and over up until a few days ago.
let's face it. ms has all the money in the world.
they can find a way to detect anything if they really wanted to.
it's no different than Nintendo, Sony, or m$ claiming their console is unhackable, yes m$ has a new method for now, sure the new fw won't be detectable, but eventually m$ will find another exploit in their own system to find what fw your on and ban you, it's the risk you take when modding your 360
