Wouldn't work. What gets hashed and checked is a re-created HV loaded into memory (theory). I have a feeling atlas use temp memory, so would be tricky. Like Dwack said, trying to reverse/apply retail changes to the main HV would defeat the purpose of xebuild.I was under the impression that the HV will only have the right challenge responses if dumped off a console signed in to live!
So here is my idea may be a long shot but i don't think so someone who has atlas needs to dump there HV why signed in?
That would be the simple way there is obviously others
