Snowbreeze IPSW restore problem

[Dubro]

I get to the part of the restore where it says "verifying iPhone Restore With Apple" and it bombs out with error 1602

Phone is a 3GS previously jailbroken. It was at firmware ver. 4.0.1 and it has new bootrom. I used Snowbreeze to create the ISPW then when it goes to iTunes and I press shift/restore it starts doing it's thing then bombs out with the error. please help. thanks.

Never mind. I fixed it. It was the host file. It needed to be set back to stock. Here is a good link on how to do it:
How can I reset the Hosts file back to the default?
