Default [Q] portable Hotspot not working(Note 2)

Hi, I have a problem with my note 2. I have looked everywhere and I cannot find a solution to this. So, the problem is that when I turn the portable hotspot feature on, it works but it automatically turns off in 2 seconds. I also noticed that when I try turning it on, the other settings buttons do not work either.(WiFi toggle on button, bluetooth etc) I am running 4.3 rooted( no roms) help will be appreciated
thanks
