    Default help; 3gs 4.2.1 jailbreak

    hello,
    i bought one iphone 3gs with firmware 4.2.1 and base band 05.15.04 which was not jailbroken.So i went through redsn0w procedure to upgrade to 06.05 and i encountered following problems
    1)it stucked on uploading ramdisk
    2)after few tries it went through it and stucked on Flashing base band
    after that with few tries somehow it went into recovery mode

    then tried to restore back to downloade 4.2.1 restore file through itune but it gave error 1015 and again went into recovery mode.

    so now my problem is it's going in recovery all the time even if i switch it on and it is not connected to pc.

    i tried so many times but it stucks on flashing base band and not going through.

    pls help me out ...

    Sounds like you had issues with either your computer or your USB ports.
    You should try another USB port or another computer.

    Is it old or new bootrom 3GS? http://theiphonewiki.com/wiki/index....ootrom_version

    Also, read http://www.hackint0sh.org/f204/196391.htm to understand why you get the 1015 error and how to avoid it.

    I gave you the answer in the thread I linked to, you need a 4.1 SHSH and a 4.1 custom IPSW made with pwnagetool - that's the only way you are going to get out of this mess.

    This requires access to a Mac to make the custom IPSW (Pwnagetool is mac only) - the custom IPSW restore technique for 4.1 does not work if you don't have a 4.1 SHSH saved.
    Plus if you failed to save your 4.1 SHSH before Apple stopped signing 4.1 restores in early December 2010 - you can now never get a 4.1 SHSH

    No one has yet published a way to restore a new bootrom 3GS to iOS 4.2.1 when you have loaded the iPad baseband.

    In other words... you get 1 chance to jailbreak/update the iPad baseband on iOS 4.2.1 with a new bootrom 3GS, once you get it working - then you are limited to a tethered jailbreak (every time you reboot the iPhone you need to run redsn0w and select "just boot pwned for now")

    Once you load the iPad baseband on iOS 4.2.1 3GS/new bootrom, you need to be EXTREMELY careful to avoid doing anything that screws up the iPhone to the point where you require a restore (because it will always fail with error 1015)

    hello,

    i tried redsn0w jailbreak again then few updated things are
    1)if i try to install cydia only then it goes through all the process and stucks on apple logo for a while and goes back to that itune+usb wire (recovery)sign
    2)when i try to just tethered boot option then also it goes through all process and stucks on pineapple sign ,again comes back to recovery sign
    3)and when i try install cydia and ipad band both selected that time it stucks on flashing band(dont interrupt)and goes back to recovery mode.

    is that so my iphone band is already upgraded?so what to do next?

    pls help me out

    The SHSH is unique to your phone and a specific iOS version - it's impossible to use someone else's SHSH, also if you bought the phone after 3rd december, then you could not request a 4.1 SHSH.

    Your mistake was not to jailbreak directly but to then try and restore an original 4.2.1 IPSW

    You need to make your own custom IPSW. It's illegal to share custom IPSW.
    I am unsure if it will work for a new bootrom 3GS anyway.

    Yes your baseband is most likely already updated.
    TinyUmbrella can check this.

    Really good news.

    Put in the SIM card you want to use with this phone. Run redsn0w and select "install cydia"
    Then after the redsn0w process is finished, it should boot up to the springboard screen. If Cydia icon is white run Redsn0w again, use the "just boot tethered for now" option
    Install ultrasn0w from Cydia, reboot.
    run Redsn0w again, use the "just boot tethered for now" option.

    There are a few command line options you can use to create a script to semi-automate the "just boot tethered for now" option.
