    As stated in the title, i tried to do my downgrade to 5.1.1, i have my shsh from 5.1.1. I used red snow to stitch a restore ipsw and tried to restore. I kept getting a 1604 error.. not sure of the solution. :mad:

    i tried using a different ipsw of the iphone 4 (cdma) 5.1.1 software and it still didnt work.

    I sometimes get that error.. I think it's a USB related issue. The only solution that has worked for me was to do the procedure on a different computer. In my case a cheap netbook from a few years ago worked when my more modern pc didn't.. I tried new cables, wiping USB controller from device manger, etc... Only the netbook worked (and this has happened more than once). It might be a path to explore for you, I hope it helps.

    I was having same problem when I used redsn0w. So, I came here and I found this great thread about downgrading using snow0breeze, and I tried it and it worked without any error.

    Here is the post for you:

    FYI Sn0wbreeze is PC only. I haven't tried downgrading so I have no experience to offer there.

    from the iphonewiki:

    Error 1604
    Device was not pwned (signature checks were not blocked). Custom firmware can't be restored. Can also happen when there's a problem with the IPSW.
