First of all you need to power off your device. Then you turn your device back on But you hold the power Button volume down button and home button at the same time then a warning screen will show up asking you to release everything and hold the volume up button. After you complete this process your phone will be back to normal and you can root it if you like. I would recommend KingRoot for routing your device. Hope this helps
