Hi, You need to reset your phone. Here is a link that shows you how to do it. Be aware that a hard reset will erase all of your downloaded apps and user data. http://www.hardreset.info/devices/nokia/…
Try power on button together with volume down, after vibration then release the keys after you see this sign(!). Follow this steps: volume up , volume down, power on, volume down. Wait for the phone to restart
