    Hi everybody,

    Is there any way to backup & restore the iPhone 3GS back to it’s original settings if something goes wrong?

    Hi guys, Ive downloaded the custom ipsw file for windows users but the zip file contains multiple files and folders rather than the usual .ipsw file itself. Please can someone enlighten me on how I can change the folder to the ipsw?

    Cheers in advance

      JFBourne11 years, 11 months ago

      Hey Brown what you have to do is unzip the first file and extract all the file inside into a folder in your desktop. Now create another folder in your desktop and name it whatever you want, example “ipsw”. Then go to the first folder you created and start unziping all those file inside. Every time you unzip a file extracted it to the second folder you created “ipsw.” Do the same for all the file inside the first folder. After you are done with all the file you will have a complete ipsw inside the ipsw folder you created.

      I have the same problem as RAJ.

      I’m stuck in restore mode with 1604 error


        thermanator11 years, 10 months ago

        I had similar error (1600) and someone told me to just restore it without putting it in restore or dfu mode and it work but i now have no cell signal and don’t know why. so maybe try that but if you know of any help for my problem please respond.

    Hey Bryan,

    Do you have a link to a working IPSW file? I have D/L countless ones only to find that they wont work. Also will it still work if you have the new baseband version 05.11.07????

    mark11 years, 11 months ago

    Hey, bryan.

    thanks m8! u just seemed to clear the CLOD 9 on myu head ;-)

    Hey Alex,

    You don’t need to download PwnageTool 3.1 at all. I was totally frustrated too, until I realized that the custom IPSW file is available on the web. Download it, and then install it as above starting at step 8.

    Scuba11 years, 12 months ago

    The above instructions are great if you are a MAC user but for windows users it seems to be more difficult to find detailed instructions on how to jail break a 3G on OS 3.1

    Scuba11 years, 12 months ago

    what you say sounds like it alex but i cant find where to put the custom restore file on my computer so that itunes 9 picks it up for me to restore to.
    I had no idea that this jail breaking thing was going to be such a mess around.

    Hello, I am a Windows user. I cannot find the download of PwnageTool 3.1 for Windows. Is this mean that I don’t need the tool to create the IPSW file and just use the custom one from the link above ? i.e. I only need to download the custom IPSW file, start iTune, backup the iPhone, restore the customed IPSW file using iTune, and then restore the data from the iTune backup ?

    Many thanks,

    Scuba12 years ago

    Im confused. where are the instructions for windows users?
