    I am trying to update my developer registered iPhone 4 to iOS 6 and keep getting this "An unknown error occurred(-1)" .

    yeah, restoring to 5.1.1 works but so far no luck in getting it to update to iOS6.

    You are on the latest and greatest iTunes right?

    If so a restore or DFU restore might be needed.

    I know this is old but I have to tell you this!
    I tried updating my Iphone to Ios6, got the recovery mode screen and then it got stuck there! Got error code 3194, ok, try again (about 10 more times) now I got error code -1. Tried google, tried EVERYTHING (dfu, tinyumbrella, ireb, irecovery,) you name it I tried it! People told me that -1 meant my baseband was fried and I could kiss my Iphone 4 goodbye (hell no)
    After 2 days of trying stuff I was fed up with software and Itunes!

    Here's what I did: I removed the battery - reinserted it - same issue
    Then I removed basically everything else (my warranty is no more anyways so that didn't bother me) followed the steps from Ifixit. Made sure to attach all the cables and whatnot really good, connected it to itunes - restored
    Oh my apple, it worked!

    Me 1 - Iphone 0

    -1 and 3194

    Same error codes here (-1) and (3194) when trying to upgrade to 6.0
    Restore to 5.1.1 also not working
    What else can I do? Also disassemble my complete iPhone?

    That's the only thing that worked and trust me I tried everything else.
    Start by just removing battery first and try if it works that simply for you!

    3194 means your host is not pointing to apple

    Download TinyUmbrella and in advanced make sure request SHSH from Cydia and Set host to cydia are UNchecked

    flush DNS or restart.

    error -1 indicates a BB UPGRADE problem, not that it is fried, if you have that and phone is in recovery kick it out of recovery with redsn0w or TinyUmbrella
