black screen on iphone

[Cybertekww]

I have downloaded the xcode files, installed them and changed all the details like I have done before but the iPhone I have plugged in is just a black screen after it loads. The pokemongo spoof app opens, opens the pokemon go app and I can log in and the loading screen displays but after that it is just a black screen. Is it an issue for me or is the whole system now not working? Im stuck home and cant get out to play so want to try spoofing again.
