  • [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!

      Did you follow the example on the first post, it should be there. Perhaps re-read it.
      Keep trying, you'll be good to go.

      Worked well for me. It got stuck and wouldn't go into DFU mode, but worked after the third try. Thanks for this. LOL, I didn't update to iTunes 8.2 first, so doing it now.

      Spoke too soon. Phone isn't activated. Doing again and activating prior to using redsn0w. Hopefully it works this time.

      First off you were reading the wrong thread if you have a 2G.

      Can anyone help a noobie? The 3.0 ipsw download link at in the guide is not giving me a workable firmware file. I download it, extract it, and get "file not found" Shouldn't there be an square icon with a musical note? Ive DL'd six times now from the MMI site and still no luck. Anyplace I can get the iphone 1,1_3.0_7A341 restore.ipsw file?

      Hi all, question - Okay I have not updated my phone to 3.0 yet in Itunes, now I have itunes 8.2 and do I simply click shift restore then load the ipsw for iphone 3.0 then let itunes finish, once i have the iphone 3.0 on my Iphone 3g I then start the redsnow process correct?

      Ok, I have a question.

      I just bought my first iPhone on June 10th. I upgraded to 3.0 the day it came out. I just backed up and restored my iPhone as recommended in the OP. I am now at the iPhone setup in iTunes. My question is, do I setup as a new iPhone or restore from my backup which I just made?

      Thank you.

      is your iPhone1,2_3.0_7A341_Restore.ipsw end up as a iPhone1,2_3.0_7A341_Restore.ZIP File? if so all you have to do is rename it to .ipsw and redsnow will be able to find it..do not extract that zip file..it won't work

      Yes but does it matter which one I select before using redsnow? Or is either one fine?

      Does anybody know whats up with the hanging "Waiting for reboot" screen? I'm going to wait another couple of minutes and see if any progress is made; however, I've already been waiting for about 5 mins. :/

      I know it says to wait for ultrasnow if I want to unlock, but I don't need to unlock until January 2010 when my contract runs out. So if I use this redsnow method to jailnbreak now, does that mean I will never be able to unlock with ultrasnow? Or just not until ultrasnow arrives?
