I've got an iPhone 5s which is now stuck on the Apple startup logo. I was wondering if the fantastic MacRumors community could help. I was using my iPhone, closed an app, and then the device froze on the home screen. It eventually restarted and when it turned back on, it was just displaying the Apple boot up screen, then turned off. Now, I when I boot the phone on, it goes to the screen, and then carries on showing the Apple Logo until it just turns off. I have tried restoring through iTunes, but it doesn't work. Can anyone give me any advice?
