Crap...Need help ASAP!

[djevolushun]

So, I was running ios5 beta 7 and decided to go back to 4.3. The problem is I was trying to go back to 4.3.3 and that was the wrong IPSW. It obviously didn't work. So, I tried to do a factory restore through iTunes and it keeps failing. I tried TinyUmbrella and that didn't work. I also tried fixrecovery43 and that didn't work. I also downloaded the IPSW for 4.3.5 and it still locks up. I need this phone to work like an hour ago and did not expect this. Can someone please help!?

EDIT: I have a factory unlocked iPhone 4 and it was on 4.3.5 when I got it.

Is there any specific error code it's giving you?

Check you host file and delete anything that has gs.apple.com in it and click restore

I did that and it worked!
