Windows Users avoid iTunes 9.1

Author: BigBoss  //  Category: Jailbreak, News

It appears that Apple has released iTunes 9.1. If you are on windows, I would avoid using this. It seems to have problems with blackra1n because blackra1n uses a specific DLL that has changed.  In general, I recommend never updating iTunes. I have v8.0 still and am quite happy not having to update that horrible piece of software.

Anyways, here is a quick summary:

1) Itunes 9.1 is out
2) The new dll will mess up blackra1n running in windows. If you have a tethered jailbreak, you would be unable to rejailbreak after rebooting the iphone with blackra1n. I believe you can use redsn0w but there may be some issues with using redsn0w on an already-blackra1ned device.
3) There may be sync problems with it until you reboot.
4) Redsn0w seems OK with iTunes 9.1. So if you’re using that you should be OK.
5) OSX iTunes seems ok. Problem is blackra1n + windows only.

The old saying applies. If it’s not broken don’t fix it.  If you have already updated itunes, you can get an old version here. Your steps to install an old version are a bit tedius:

1) Uninstall the current itunes
2) reboot
3) Install new itunes

Note: it is probably also possible to locate the old itunes dll files and put them in the blackra1n folder and blackra1n would probably work again.

    You know what assuming does. You only mention Windows. What about the MAC OS? Has that not been looked at yet, or is it totally fine to update iTunes on the MAC?

    ih8snow has released “BlackBreeze”. If it’s any good, I don’t know, but it’s worth mentioning.

    iTunes 9.1 safe for overall jailbreak, unlock, PwnageTool, redsn0w mac+pc, DFU mode, saurik’s server. (blackra1n broken, not Apple’s fault)

    Problem solution:
    For Windows XP users, put Blackra1n.exe in this folder C:\Program Files\Common Files\Apple\Apple Application Support

    And run Blackra1n again…Works for me.
    The ASL.dll is located in that folder on my WinXp.
    Alternately for other OS, do a search for ASL.dll and put Blackra1n in that folder and run.

    I had a similar problem some weeks ago, with the QTCF.dll issue. I just copied my blackra1n.exe into C:\Program Files\QuickTime\QTSystem and ran blackra1n from there…Problem solved..

    Blackra1n not working after 9.1 iTunes update : my solution

    1) find your Apple Application Support :

    for example : C:\Program Files\Fichiers communs\Apple\Apple Application Support (french system)
    C:\Program Files\Common Files\Apple\Apple Application Support (english system)

    2) copy to your blackra1n directory :


    3) THAT’S ALL !! run blacra1n and enjoy your jailbroken iPhone again ;) :)

    Hope this helps :D

    PS : no need to downgrade iTunes any more …

    Go to and go to fix blackra1n for itunes 9.1 and it will solve all of your itunes 9.1 problems so go ahead and install 9.1
