  • [Windows] How to Jailbreak iPhone 3G Firmware 3.0 with RedSn0w
    This guide will teach you how to Jailbreak your iPhone 3G running 3.0 firmware using RedSn0w on Windows. You can unlock your iPhone 3G AFTER following this guide by using UltraSn0w. Directions on that are here. Anyways, lets continue.

    I strongly recommend you backup and restore your iPhone 3G to 3.0 firmware via iTunes BEFORE you begin this guide. By strongly recommend I mean restore to 3.0 firmware.

    You will need RedSn0w 0.7.2 which you can download here along with the iPhone 3G 3.0 firmware file available for download here.

    Once you have downloaded everything, extract redsn0w-win_0.7.2.zip to a location on your computer. You should see redsn0w.exe. Run it.

    Click Browse.



    Browse to where ever you downloaded your iPhone 3G 3.0 firmware .ispw, select it, and click Open.



    RedSn0w tells you that the ISPW has been successfully identified. Click next.



    You'll see a little window that says patching kernal for a second.



    Select Install Cydia and click Next.



    Plug in your iPhone 3G and turn it off. Once it is off click Next.



    RedSn0w gives you instructions. We are entering DFU mode now. First hold the power button for 3 seconds.



    Keep holding the power button and start holding the home button for 10 seconds.



    Release the power button but continue holding the home button for 30 seconds.



    RedSn0w does its thing. Let it.









    Finally RedSn0w has finished loading everything onto your phone. You will see a pretty screen on your phone as it is being Jailbroken. Don't mess with your phone will all this is going on. After your phone restarts you are done!

      It's not a zip file, it's an ipsw. If it has a .zip extension rename it to .ipsw

      Compress the file.
      After compression, remove ".zip" and add ".ipsw" to the end of the file.

      after the last step, my mobile displays a message saying "Downloading Jailbreak Data" and then nothing happens and the msg stays on the screen, without jailbreaking the phone...
      Could you please let me know the reason for this..

      so i've jailbroken and unlocked my 3G twice using redsn0w and ultrasnow. i'm currently using firmware 3.0 and i'm considering an update to 3.1.2 but i still have 4.26 baseband so obviously i don't want to update through iTunes. i've already downloaded a copy of the 3.1.2 firmware but redsn0w specifically says to use your "CURRENT" firmware version. knowing that i don't want to update via iTunes can i just choose the 3.1.2 firmware in redsn0w use this as a way of updating? thanks in advance for any help you can give

      ps if the answer is yes should i restore my iphone before beginning this process or can i run redsn0w on my already jailbroken & unlocked phone?

      You need to use pwnage to upgrade without updating your BaseBand. You'll need to use a mac.

      Any guess on how long it should take? The screen has been blank for about 30 minutes and the window still says waiting to reboot.
