Device is stuck on a white screen with a black Apple logo, and isn't recognized in iTunes.

Hello Lissy5555,

Thanks for using Apple Support Communities.

I see that your iPhone is unresponsive and will not boot past the Apple logo. I know this must be frustrating, as I would feel that way if my iPhone wasn't working, so in order to get this resolved please follow the steps in the support link below.

If your iPhone, iPad, or iPod touch doesn‘t respond or won‘t turn on

Cheers.
