Are you 100% sure you are in the new pwned dfu mode? Did you use redsn0w 0.9.6b2 or pwnagetool 4.1.2

Your error suggests that you aren't

Redsn0w 0.9.6b2 on windows you mean?

And you made the custom IPSW yourself using pwnagetool 4.1.2 on a mac?

Don't trust custom IPSW you download from the net.

You know we can't do that.. (it's illegal to share custom IPSW) Run a copy of 10.5 or 10.6 virtualized on your windows machine and make the IPSWs yourself

when i download its original firmware from iclarified its download 4,1 but in dmg format how to get its ipsw
