Unlocking the debug mode one the Xbox One is quite an easy process, and you do not need to hack the Xbox One to do so. Simply Go to "System" and press then press LB, RB, LT and RT. This should unlock the developer settings on the Xbox One. You will however need a legitimate SDK licence for this to be of any use, however who knows what this could lead to in the future.
