If your Kinect is not working properly like mine was. Mine kept telling me to it was powering on and off and wasn't recognizing my commands. I decided to do a factory reset of the whole console and everything is now working good again! After speaking with and Xbox support rep they told me to send it in and it would be about 30 days before i get a new one. Yea no thanks
I think with all the new updates and Titan fall dropping and the profile problem that was going on yesterday my Xbox got in a funk and just wasn't working. Try this if your system is being stupid like mine was. Hope it helps!
