  • [Windows] How to Jailbreak and Unlock iPhone 2G Firmware 3.0 with RedSn0w
    This guide will teach you how to jailbreak AND unlock your iPhone 2G running 3.0 firmware using RedSn0w on Windows.

    I strongly recommend you backup and restore your iPhone 2G 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 2G 3.0 firmware file available for download here. You also need the 3.9 and 4.6 bootloader files. Download 3.9 here and 4.6 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.



    Find your iPhone 2G 3.0 firmware file you downloaded earlier. Select it and click Open.



    RedSn0w tells you that the ISPW is successfully identified. Click Next.



    There will be a quick pop up.



    Select your options to Install Cydia and Unlock. If you don't need to unlock your iPhone 2G you can de-secelct Unlock



    If you are unlocking you need to located the 3.9 and 4.6 bootloader .bin files you downloaded earlier.









    Now that you have told RedSn0w where the bootloader files are click Next.



    At this point you should make sure your iPhone 2G is plugged into your computer AND turned 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 and Unlcoked. Don't mess with your phone while all this is going on. After your phone restarts you are done!

      Not trying to give you a hard time, but your missing something. No one else has had a problem like this that they were missing. Try it again.

      If you found the zip file, extract it to your desktop, I'll see if I can find the files in the mean time.

      Try this link, it will explain how to get into DFU mode.
      Don't worry, you won't screw up your phone, it can always be restored. Good Luck

      DFU, this is the only way, if your getting a error it's not in DFU

      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 itís in restore mode.

      Alternative Method:

      Step 1. Connect iPhone to USB then listen to the sound when it connect and disconnect.

      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.

      hmm maybe I'm doing something wrong, are we supposed to restore to 3.0 and then use redsnow? Because when i use redsnow it takes like 3 seconds for it to work, and in the end it doesn't unlock nor jailbreak.

      I follow your instruccions and it makes all the sounds you mention but when i try to restore and update it gives me error 9006 and it mentions about a problem dow loading the software. Right now my phone just stays on dfu. when I try to use redsnow it sits with the pic of a hard drive and when it finishes goes in to dfu again.

      Really appreciate the help i am geting. I know we will get it

      Do you have a link to that IPSW that you used? I followed the instructions to a T and I can't get out of the first 'waiting to reboot' screen. I must've tried about 20 times now and I am certain that I entered DFU correctly...I'm going crazy here. Any help would be greatly appreciated!

      EDIT: I used Red Sn0w on my XP operated laptop and the jailbreaking worked flawlessly! I am now unlocked and jailbroken to 3.0 on my 2g iphone =) For some reason earlier, I couldn't get past 'waiting for reboot' screen on my Vista operated computer, but after trying on my XP operated laptop I was able to get past 'waiting for reboot'
