if you can email me on [http://anthonysimpson2008@gmail.com|anthonysimpson2008@gmail.com], I will be happy to help you get you back onto your phone. I am Remote Technician, mainly PC's and Laptops, BUT I do work with Mobile Phones (Android) and Tablets. If you still require my help, please feel free to contact on my email.
