Hi, I had my iPhone jailbroken, and they cant be shut down or you'll have to restore them. I tried restoring it, it took 3 hours. When it was done it didn't turn back on. All I saw was the apple logo. I tried to do it again, but now the phone won't turn on. The apple logo won't even appear. I need help!

Hi good Night,

I did try all the recommendations but my Iphone 4S isnt giving me the option to connect it to itunes. Once I remove my hands from the sleep and Home button, the phone goes blank again and the option to restore on itunes disappears.

Help Please
