  • [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!

      On my first attempt, redsn0w crashed during the "Uploading Kernel" stage.
      I didn't panic.

      I waited for a few minutes before I turned the iphone off. I left it plugged in, and I turned it back on; everything was OK, but the jailbreak failed.

      I turned it off, waited for a few minutes, and tried again.

      Much Success!

      it seems like most bugs are worked out now. yesterday i jailbroke 3g it worked fine but winterboard would only apply half of the themes i had and the 5icondock kept bunching up to the left(big problem for most), the phone just ran slower than normal so this morning i restored and re-jailbroke again using redsnOw and everything works fine. the only "problem" i have is tweaking themes via ssh i go to library/themes and it gives me a error message about wrong folder, but i located it in the stash folder... weird!

      any ideas anybody?
      most browsers add the .zip file extension to the downloaded file, especially on a windows pc. Find the file and rename it, in the rename..ONLY delete the .zip that follows the .ispw and the file icon should change and it should be recognizable and working at this point. Hope this helps
      Example: original file "filename".ispw.zip corrected file "filename".ispw

      Im still struggling, even after redownloading redsn0w and iPhone1,2_3.0_7A341_Restore.ipsw.

      I can get the phone into DFU mode and I get as far as the image below and nothing.



      Any help would be appreciated.

      Everything went...pretty much flawlessly for me, except that apps that I had both "unhidden" using Poof and also unhidden using the "enable restrictions" hack are not visible. Unfortunately for me, this also includes Cydia.

      UPDATE: problem solved. I simply toggled "enable restrictions" one more time, and all was well. Winterboard, 5 icon dock, everything working. Btw, I copied and pasted the above paragraph (I'm on my phone). Yay 3.0!

      I then cancel cancel the operation, then re-open redsn0w and go through the procedure again. It then goes through all 3 stages and gives me the following.



      And then stays on a backlit screen with nothing happening.

      try to restore your iphone to a fresh version of 3.0 using itune then jailbreak using redsnow again

      So the jailbreak worked perfectly fine. But now iTunes is telling me it can't communicate with my phone and to restore it. If pwnplayer was working this would be a non issue, but it isn't yet. Since I currently rely on my phone as my main portable media player I'm kinda stuck now. Any help?

      What browsers do this? Opera never has, I can't think of an instance where FF has either, but FF is just a weird browser anyways so I guess it could be an FF issue.

      Unfortunately, I have heard that there will not be any quickpwn anymore. Kinda bums me cause it's always been more stable.
