  • [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!

      You can try an update & see what happens. If it's hung up you may need to Restore.

      Backups do take forever on Window. I have my 3G synced with a Macbook. It takes 1-2 minutes on a Macbook.

      That's a choice you have to make, syncing to a previous back up only takes a few minutes really.
      It will also bring back most of your stock settings and all you notes and contacts etc.
      Make sure you don't have any hidden apps or apps in categories or web clips.

      When you download it from the front page of this thread, save it to your desktop and change the .zip to .IPSW

      You will not lose your contacts if you sync from a back-up after the jailbreak.
      There will not be a Quickpwn, this is it. Sorry

      Tried this a half dozen times and it keeps telling me it cant find the device and check out youtube on how to put your phone in DFU mode . I even tried on another computer . I wish we had QUICKPWN to do this on . I never had problems with that program .

      You have to begin each process with a clean 3.0 install. That's the reason you go into DFU mode.
      Sorry, there will be no quickpwn, this is it.

      I thought the firmware file that is given at the beginning of this thread was what we needed . Are you saying I need to restore to it first then use it again with redsnow ?
      Or do I need to totally wipe my phone and update it through itunes and then use the redsnow and the firmware file that is provided here ?
      I am sure there are others that have this problem . Thanks

      u guys dont extract it, go to ur folder where u placed it, go to tools and go to folder options, u will see 3 tabs, general, view, and search, go to view, scroll midway until u see "hide extensions for known file types" and uncheck it, then apply and u can see now that the ispw file says iPhone1,1_3.0_7A341_Restore.zip. all u do is rename the file to iPhone1,1_3.0_7A341_Restore.ispw, and then it turns to a cube type icon and its ready.

      basic directions, 1. download all the files, 2. then on the itunes 8.2 hold shift and click restore and u should have ur ispw zip file already changed to iPhone1,1_3.0_7A341_Restore.ispw. after the installation is fully restored u will see on ur iphone the emergency screen thingy,3. open redsnow and follow directions, approximately 10 mins for all these steps. just be careful and follow the directions

      Once I get to the emegency number screen , do i disconnect it so itunes wont continue from there ?

      my mistake its ipsw, not ispw, i always get those mixed up. as long as u have the cube shaped icon u should be fine

      naw u dont really need to do anything. itunes is just gonna go back to normal screen. ur iphone should show slide for emergency and the itunes cd wit the chord showing arrow to it. just run yellow snow. itunes will just recognize and a message will say the sim card inserted in this iphone does not appear to be supported. just close itunes then run redsnow. after thats done u can turn itunes back on again

      im actually redoing mine right now cuz it keeps crashin, maybe its the programs from cydia, not so stabe at the moment, i possibly recommend waiting until the developers figure why its crashing so much and if possible solutions.

      Ok for those people who are having problems with redsn0w here what you need to do. Delete redsn0w and firmware, download again. Some people try this and it worked. Try it on another computer. During jailbreak your computer detect your iphone as a new hardware that is been install. If it doesn't then, it will not work. I think thats where the problem is. As you are running redsn0w, check the bottom right coner of your taskbar, see if anything pops up. If it detect and install the driver, then you should be fine. Sorry, thats all the information I know, So far I had jailbreak 3 iphone 3G 3.0 and all works on the first time.

      go into the folder that said " redsn0w-win-0.7.1 " in that folder there is a file named " redsn0w " thats the program.
