Thanks for the reply, I actually figured it out.
I saved my SHSH Blobs using TinyUmbrella,then updated to 6.0 Opened redsn0w went to extras and select SHSH Blobs then Stitch. Find the 5.1.1 IPSW open it, then under blob click local and find the 5.1.1 blob you saved from Tiny Umbrella. Then it will create a custom IPSW, open TInyUmbrella then Start TSS Server and open iTunes, Shift+Restore and find the custom IPSW and wait. You might want to put it in DFU mode(iReb helps if you dont know how) when its done its on 5.1.1
Hope it helps someone
Software i used
IPSW 5.1.1 for 3gs
