I have only one SHSH blobs saved on cydia for ipod4,1-5.1 , so I downloaded related IPSW.
Unfortunately neither iFaith nor sn0wbreeze support this version of iOS. so I tried to stitch the SHSH blobs to IPSW with redsn0w

I tried to restore my custom IPSW,
when TU is started I got error (11) with iTunes
and while it's closed I got error (3194). I have to say that I remove all gs.apple.com lines from hosts.

Now what should I do? How can I restore this device?
I'm just close to give up
