This error means that your ipsw file is corrupted. If you downloaded it from the net, try downloading it again.

To check if it is corrupted, rename the extension to .zip and open it with winzip.
If it doesn't open/extract, it is corrupted.

check this post this all is explained here

I know you said you see a blank screen for your DFU mode. However, I was trying to update before, and wasn't actually in DFU and got the 1403 error. Make sure you're in DFU (check out this video http://www.youtube.com/watch?v=fiTcKMZfyfk) and just follow the directions for winpwn (I prefer the iClarified version).
