iPhone 5s has blocked me, a black screen with the logo

Question

When Click "Reset Settings," and the iPhone 5s has blocked me, a black screen with the logo of Appel and a line appearing below.
That I can do to get it working again. I've already tried with the button "Sleep / Wake" button and the "start", pressing them both at once, and nothing, it does not unlock.
Thanks in advance for information.

Hello
This bar should indicate the progress of the restoration. If not moving after a reasonable time, connect it to iTunes and try to restore from the computer.
