How to set up my factory locked iPhone 5s?

I have a iPhone 5S locked with T mobile USA. I updated it to iOS 8.0.2 since it is factory locked now i can't use my iPhone. I gets stuck on the set up screen. What should i do now to use my iPhone without any sim card and set up it?

I've had this problem before a loing time ago with my 3gs, i'm an android user now because of apples restrictions, youll have to hactivate it most likely: try this: http://www.dreamjb.com/2014/05/ios-71-activation-lock-hack-available.html
