    My phone is running iOS 6, but I want to go back to 5.1.1. I have the blobs for 5.1.1 (but just those, no other 5.x blobs), so I think I have everything I need. What I did:

    1. Downloaded the 5.1.1 software for my device (iPhone 4 GSM, build 9B208)
    2. Downloaded redsn0w to stitch in the blobs
    3. Used redsn0w to put my device in pwned DFU mode
    4. Option + restore and selected the custom IPSW created in step 2

    It goes pretty far, but in the end I'll always the 1604 or -1 errors. I have verified that my hosts file does not have the gs.apple.com line in there (that is, it's there but commented out).

    Am I missing a step? What can I do to go back to 5.1.1? Thanks!

    EDIT: Resolved, I used the fix recovery option from redsn0w, after which my phone rebooted, did some verbose stuff and now it's running iOS 5.1.1 :)

    Can you make your "verbose stuff" a little more clear? I am having the same problem as you are, in getting the -1 or 1604 errors.

    Just use Redsn0w or TinyUmbrella to kick it out of recovery, it will then reboot.

    This worked, however now I am having a problem activating FaceTime and iMessage. It keeps trying but fails. Also, when I try and install i m z d l's proxy server it says iPhone not activated.

    If you are using your phone on un-official carrier, that is common
    If on official carrier try SAM from Cydia to get push going.
