So my phone keeps restarting and once it loads up it has a x by the data bars. if i click on data is says data networked blocked. i did root my phone a few months back but then unrooted it but still had super user stuck on phone. had no problems until recently vm had my account update and i believe that was the core of my problems. it auto updated it and everything was fine for a few days until my my phone froze and i restarded it then this happens. i managed to get it back working after numerous restart but then my phone froze again and the same thing. i tried factory resetting it but has not helped but now i have no data bars on top and but if i click data still says data network blocked. the on off button is very slow now takes a few seconds for the screen to shut off and or go back on. phone seems very slow to when i touch the screen. when i go to the network screen it is just blank then goes back to the home screen. Any suggestions would be really appreciated.
