How to get iPhone 4 (iOS6) back to normal?

I recently updated my iPhone 4 to iOS6 firmware, shortly after I jailbroke it with redsn0w 0.9.13dev4, everything was fine, I even installed Cydia, but from Cydia I tried integrating a package that would allow me to have Siri. As soon as I download everything and tried rebooting the phone, it went haywire. Now it's stuck with the Apple logo on the screen, I've tried using the Just Boot option, the Recovery Fix option and I've tried re-jailbreaking it, but everything fails.iTunes won't even let me restore it, every time I try it brings up Error 3194. I'd just like to be able to use the phone again, whether it's jailbroken or not doesn't matter, Any solutions or suggestions will be greatly appreciated!

You've probably bricked your phone- it's in a state where the operating system files don't match what it expects, so it doesn't boot. If you don't have a full recovery to fall back on or screwed up the boot process to get to the recovery, there's nothing you can do. The reason it's termed "bricked" is because that's what you've got, a nice multi-hundred-dollar paperwight.

You might want to search the internet for that error code to see if someone else found a fix, but that's why every post about jailbreaking or rooting phones says it's at your own risk.
