This is not working. Also when I press the lock button it is telling me that my data network is deactivated so I press to activate it and it turns the phone off

This might require a factory restore, the factory restore will wipe out all data from your phone except the sd card files. Let me know if you want to try this, you should connect to computer with usb and try and back up all files first.
