Hi there,
I was almost desperate about that issue. I was looking for someone to take my iPhone to an Apple Store in US, when I found this post in YouTube (

If you are experiencing the same I was, try this:
1) Hold buttons sleep + home untill iPhone turns off;
2) Open iTunes;
3) Hold home button and plug the phone to your computer. The phone will turn on and the iTunes + Arrow + cable screen will appear.;
4) iTunes will recover you phone from unsuccessful recovery process.
Thanks again to Spacemonks!!
