Hi guys hope all is well.
I recently purchased a iphone 5s from someone. And it was fine for two weeks.. then i plugged it to itunes,
and it restarted!!

Now it is asking for icloud username and password!

I cannot get through with mine! whats happened?
I have checked so much online as apparently there is a bypass!
Can someone please help???
