Thread: HELP! Cannot enter into PWNED DFU mode through redsn0w as it doesnt recognize my ipsw

    Default HELP! Cannot enter into PWNED DFU mode through redsn0w as it doesnt recognize my ipsw
    If someone can please help me out id greatly appreciate it.
    I have a jailbroken and unlocked iPhone 4 running on 4.0.2 that i'm trying to upgrade to 4.3.3 while keeping the baseband.
    I get error 21 or 1600 when trying to restore to custom 4.3.3 in iTunes so I read that I need to get my phone into a Pwned DFU mode first then I can custom restore. I have a Mac so I can only use redsn0w (not iREB). I downloaded a stock 4.0.2 IPSW and redsn0w version 0.9.6 rc16 but every time i try to load ipsw i get a message that my ipsw cannot be recognized.
    I tried using a stock 4.0 ipsw - no luck
    Tried using an earlier version of redsn0w (0.9.5 beta 3 and 1, separately) and either 4.0.2 ipsw or 4.0 and get the same message.

    someone pls help!!
    i have no idea how to get into pwned dfu mode

    I believe redsn0w might not recognize 4.0.2 but will recognize 4.0. Try that. Or use the latest redsn0w with a 4.3.3 ipsw.

    I tried both. Using 4.0 and 4.3.3 - still nothing

    Buddy, unfortunately I was on the _SAME_ situation as you.

    I had to go to a windows machine, install itunes, run ireb, put the device into pwned DFU mode, unplug it, plug it back into the Mac and continue the process and restore to a 4.3.3 CUSTOM firmware without disturbing the BB.

    Best of luck for you, don't be tempted for the easy way of the 6.15.00 BB and fight for your GPS.

    Alexandra1 .... You want to load 4.3.3 ... and ... preserve your BB .... and you have a Mac ?!??!???

    Why not use the latest pwnage (PwnageTool_4.3.3.1)? It will build a custom firmware (doesn't update the baseband), activate option (if necessary), and provide a countdown timer to enter pwnd-DFU mode. Everything in one utility . Option / select custom firmware to load with iTunes.

    @ Alexandra : To just enter pwned dfu , try Redsn0w RC6 and browse to stock 4.1 ipsw. Once you are in DFU mode, you can now restore to custom firmware of 4.3.3

    Here is the link to Redsn0w RC6 : here
