My white iphone 4 won't reset?

Okay so when I try to turn on my iphone, it says I need to hook it up to itunes, we'll me as well as serval other people have tried but it just won't restore. When you hook it up to iTunes it says it needs to be restore and it will go through the process but at the end it will say iphone can't be restore.
The iTunes is updated on my computer, and the iPhone isn't updated to iOS 7.
Can anyone help me? Please?

You can try putting your iPhone in recovery mode. You can do this by holding the power button and home button at the same time until the iTunes logo comes on. From there you can restore the iPhone through iTunes.
