Just repair it using sony update service but you'll lose all your data

This can often be seen on branded phones and happens if you put a non network simcard into the phone which makes your phone think it's been lost or stolen and whoever has it now is trying a different simcard in it and as a result of doing so for security purposes will render the phone useless without phoning your network provider and going through some security questions and if you pass a unlock code will be given
