  • [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!

      When you extract the file, point it to your desktop, easier to find that way.

      Just edit it and change the file extension to .ipsw and you should be good to go.

      would base band update not help the 2G cracked phone users?

      What a wonderful guide. Everything is working except the Vibrate function. It was working on my first jailbroken. Some reasons I need to restore to factory mode and jailbreak again then the Vibration is gone.

      Anyone has solution??????

      Hi All,

      scratching my head on this one. I am trying to follow the guide but having a problem. I obviously have the 2g iphone and the following.
      Itunes 8.2
      Iphone 2.2.1 (5h11) Firmware
      red snow as per guide

      I'm trying to fllow the guide and restore my phone to the 3.0 as suggested. But everytime I go to restore everything runs fine until it prepare the iphone where it endlessly runs and then ends on the eroor 1604.
      I've tried restoring from the 3.0 download which should be used with red snow but still the same thing. At any time I can revert back to the 2.2.1 firmare just by shift+restore and choosing the firmware which works fine with no errors.

      If anyone could point me in the direction it would be appretiated.

      Thanks.

      ooh Just to add my iphone has been jailbroken before so just need the unlock.


      Update:-

      I tried a few registry cleaners, and removed the updates so itunes would load another 3.0 incase this was corrupt and followed a few guides to get rid of the error code.

      In the end i went on another pc with itunes 8.2.1 and updated from there. Unplugged where i would like to restore from i.e new phone or back up then plugged into my pc and then backed up from there.

      first off i should tell you that I am on a 1st gen iphone, went from 1.1.1 to 1.1.4 not too long ago.... now i am looking to upgrade to 3.0.

      Somebody told me i can just upgrade through itunes and it would not undo my jailbreak/unlock.....is this true?

      I d/l the necessary tools on the first page in preparation for the worst however, and I am having a few issues....

      Browsing to select the IPSW, the 3.0 restore i saved to my desktop comes up "no items match your search", Following advise i edited the names of all the extracted folders and files to end in .ipsw (which changed the icons for all of them) each one when selected in redsn0w however comes up "unable to recognize specified IPSW"

      Any help would be greatly apprectiated

      I have a little issue putting back my backed up info.

      I used this on my 1st gen Iphone, went to 3.0 and have it unlocked without any issues, but when I try to resync my 2.xx data back to my 3.0 phone it crashes the phone. Any ideas?
