Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I would advise you first off, to try a Factory Reset. (If you need guidance as to where it's to be found or how it's done, let me know - in vague general terms, such a function is usually at the end of the Setup menu, and can be called 'Reset All?')
