  • [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!

      I have a 3G. I installed 3.0. After running redsnow and following all instructions-it crashes right after the power/home+power/home button sequence. I have tried using 0.7.0 and 8.0. I am running Vista. Is there away to Jailbreak my phone and avoid this crash?

      Yes

      I plug in the phone, then power off. Then click next and follow the instructions.

      No, redsnow closes down. Unexpected error in the program.

      I have downloaded both redsnow and firmware from multiple sites and used both Explorer and Firefox to download each. Still same result.

      Sorry the program shuts down and gives error message. Computer is fine.

      iPhone1,2_3.0_7A341_Restore.ipsw, now. Started out trying iPhone1,2_3.0.1_7A400_Restore.ipsw, but that had its own set of problems.

      can you verify the firmware version on your 3g phone? perhaps that does not match with the restore version your using. also keep in mind that iPhone1,2_3.0_7A341_Restore.ipsw is for 3g and iPhone1,1_3.0_7A341_Restore.ipswif for 2g.

      Does AppTappInstaller help by chance?

      Where do I go under settings to check the firmware version?

      apptapinstaller is a very old installer used for jailbroken phones to install apps.

      i remember my redsnow crashing similar to yours before. i believe i was running the 2G firmware with redsnow with a 3G firmware phone, thus causing redsnow to crash.

      There is a conflict with installing both Cydia and Icy, you will have to restore and re-jailbreak your phone and install only Cydia, sorry.

      Put in DFU mode, restore in iTunes and then run the jailbreak again this time only install Cydia.
      In case you need them here are directions on DFU.
      DFU mode
      INSTRUCTIONS
      Step 1. Turn off iPhone
      Step 2. Hold down the power and home button.
      Step 3. When you see the Apple logo, release the power button but continue holding the home button down.
      Step 4. Open iTunes and wait for it to tell you that it detects iPhone in restore/recovery mode.

      Alternative Method:
      Step 1. Connect iPhone to USB then listen to the sound when it connects and disconnects.
      Step 2. Hold the home and power buttons until hear the disconnect sound then release power button.
      Step 3. Wait until you hear another sound then release home button.
