Ya i was exiting IE and put in Halo 4 and i guess it was trying to load it and it froze so i shut it down manually and now it just stays at the initial loading screen when i try to start it up. Ive tried taking out the hard drive and starting it up without it and its the same. ive tried it without my ethernet hooked up and ive tried holding down the sync button while it starts up as well (idk if that even does anything) but nothing changes. im also not able to start it up with my controller and ive even left the system on for multiple hours thinking it might load but nothing happens. help!
