[HELP 3GS] Firmware is Corrupt

[Jawo]

Does anybody here knows how what the heck just happened when I tried to update my iPhone 3gs with 3.x.x version to 4.2.1?

IT SAYS THE FIRMWARE IS CORRUPT! What should I do? download another? or did I missed sumthing?

Yes, download the .ipsw again. The one you have may have gotten got corrupted during the download.
