How Can I Fix My Iphone 4 Stuck In Dfu Mode

I used the JailBreakMe.com, I went to Restore phone to remove the JailBreak. Kept receiving errors, unable to connect to device when the Apple sign came up during restore and iPhone was being prepared with the little loading bar that wasn’t filling up. Eventually I tried Tiny Umbrella and it got Stuck in DFU.

Now I am unable to Exit Recovery/DFU mode with or without Tiny Umbrella. While using Umbrella’s Fix Recovery option, it loads a black screen with a lot of coding and just stays there or goes to a white screen and stays there.

Any detailed steps would be very much appreciated.
