Ok. It actually went past the recovery screen but now its just a blank screen. It still says preparing iphone for restore.

Ahh, well I just got the 1604 error after trying to "restore ". I think my host file got jacked up a while back and I couldn't figure out how to fix it.
 
Use Google to find out how to access and modifiy the hosts file for your system and remove all lines that have apple.com in them. Also redownload the IPSW. It may be corrupt.
