Update error resolution with ASL.dll blackra1n

Some users have reported the occurrence of a particular error after
updating iTunes to version 9.1. More specifically, performing some
programs after updating iTunes to the latest version was
an error indicating a missing ASL.dll. This
problem, keeping in theme iPhone has plagued some users intent to
Blackra1n use to run the jailbreak your device.

The solution to this problem, as regards the implementation of Blackra1n is quite simple. It will simply copy the executable of the tool designed by GeoHot Common Files within the directory located within Program Files. More precisely, the paths to copy the executable Blackra1n depending on the version of operating system currently in use are:

Windows 32bit: C:Program FilesCommon FilesAppleApple Application Support
Windows 64bit: 64 Bit – C:Program Files (x86)Common FilesAppleApple Application Support

Once copied Blackra1n in the right path you can run it from there or create a desktop shortcut to solve the problem calmly and run the jailbreak.

  19. Tyler says:

    This absolutely worked without a doubt! Thsi problem occured for me after having upgraded from Vista to Windows 7. When I connected the iPhone, it gave some message about having to restore it. Your choices were as either a new phone, or your old phone settings. Anyway, after using the above solution, I can confirm that not only does it work, but that all jailbroken settings were retained after such a backup.

  20. TJ says:

    Thanks for the solution…

  22. charles says:

    Bacily what this is saying is copy one of the codes, go to my computer, paste it in the address bar, find the asl.dll click it, and open it with blackrain(youll have to fin it, ie.desktop,my documents etc.)

    hope this cleared it up

    another solution is to: just go to blackra1n website and instead of downloading the program just run it and it will work the only thing is you will need to be connected to the internet to do it.

    Thanks!! :)

  76. David says:

    Thanks man for all your work, your pretty darn good with computers, and electronics keep up the good work. Thanks Again.

  77. AndyO says:

    You should also be able to resolve this by adding the location C:Program FilesCommon FilesAppleApple Application Support to your PATH environment variable. Right click My Computer > Properties > Advanced > Environment Variables. In the bottom pane look for the entry called Path, select it, click Edit, then at the end just put in “;C:Program FilesCommon FilesAppleApple Application Support”. Important to note that is a semicolon at the front as it uses semicolons as delimiters, and of course don’t put in the double quotes. If you’re using 64 bit Windows use the 64 bit path. You may need to restart windows.

  78. Kong says:

    This works well.. Thanks!!

  79. Samman says:

    it says needs admisistrator permisson even though im am administrator…

  80. Miladintjuh says:

    how long should it take?
    it says 30secs, i left my ipod in for 3 min. still doesnt work!
    please email me@ scouting_m@hotmail.com

  81. big c says:

    nice one worked

  82. waitlessc ayc says:

    To clarify for newbies: re-install the blackra1n.exe and select “Save” (not “Run), then click C: and then Program Files and then Common Files, etc., etc.

    Then go back to that “Apple Application Support” folder you saved it in and open it. When you run it this time it will work :)

  83. clubba says:
