Can someone help me now?
I'm still getting a 1600 error.
I put my iPhone 3Gs into pwned dfu mode with iReb, made a no-bb ipsw and stitched the shsh onto it, i've flushed my dns, checked my hosts and still nothing. Please help me, ive been working on this for countless hours

Oh and im on an iPhone 3Gs new br, ios 6.0 trying to downgrade to 5.1.1
------
the phone isn't activated yet either because the sim tray is damaged. This is actually the main reason why i want to downgrade because I want to hacktivate the phone. If you guys have a way to hacktivate 6.0 please, that would help so much.

I got it to work somehow, what i did was this:
Put my phone in recovery mode and tried to restore with the no_bb ipsw that had the shsh stitched, it gave me a 1604 error so i tried it again. While it was said "preparing phone for restore" i opened ireb and used the recovery loop fixer.
after that i used ireb to put it in pwned dfu mode and tried to shift restore using the no_bb ipsw with the shsh stitched. I worked this time, but ive tried it before and it never worked until now. Im not sure if it was because of the recovery loop fixer, but it worked.
