Tutorial: iPhone 3.0 Jailbreak Using RedSn0w

By , Jun 20, 2009

This RedSn0w guide & tutorial will show you how to use RedSn0w to jailbreak your iPhone 2G, iPhone 3G, or iPod Touch 2G. Note that this step is required to unlock your iPhone 3G using UltraSn0w later on. For more information about the latest jailbreak methods for each iPhone, I recommend you read this before doing anything.

This guide is for PC users but I assume the steps are very similar on Mac. If you want to build custom firmware files with more flexibility it is suggested that you use PwnageTool on Mac OS X (PwnageTool jailbreak tutorialPwnageTool unlock guide).

1. Before doing anything, make sure you have the latest version of iTunes and the latest firmware 3.0 installed on your iPhone.

2. Create a new folder on your desktop. In this folder, download RedSn0w as well as the latest 3.0 firmware for your iPhone from our iPhone downloads page (make sure you pick the right firmware).

3. Unzip and launch RedSn0w.

4. Click “browse” and select the 3.0 firmware you downloaded in a folder in step 2.

5. Once the firmware has been successfully identified, click “next”.

6. Select “install Cydia” and click “next”.

7. Make sure your iPhone is plugged into the computer and that it is off. Click “next”.

8. RedSn0w will then guide you to put your iPhone into DFU mode. Hold down the power button for 2 seconds. Without releasing the power button, also hold down the home button for 10 seconds. Without releasing the home button, release the power button but keep holding the home button for 30 seconds.

9. If done correctly, your iPhone should reboot and the jailbreak process should start. This step may take up to 15-20 minutes so be patient.

10. Once this process is over, you will get a message saying that it is “done!”

11. Click the “finish” button and reboot your iPhone. The reboot may take up to 10 minutes so again, be patient.

12. Congratulations, you just jailbroke your iPhone 3.0 with RedSn0w. Cydia should now be on your springboard :)

    I tried everything EVERYONE said and it would work fine until it got to the downloading jailbreak data screen then it would just sit there forever! So here’s what finally worked for me:
    -Right Click Redsn0w
    -Click Properties
    -Click Compatibility
    -Click Run In Compatiblity Mode For: Windows XP (Service Pack 2)
    -Then Clicked Privilege Level : Run As Administrator
    -Clicked Apply Then OK
    Then tried again and it worked and was done within 10 minutes! 

    I’ve done everything listed above and I’m still having problems.

    When I get to the reboot stage my Redsn0w program says “not responding”. Any idea on how I can fix this?

    I using 4.3.3 (8J2) iphone and I’m using the 4.3.2 restore with Redsn0w. I’m also asked when I find the ISO in Redsn0w is my 3GS a newer model. When I view my serial number it doesnt look anything like the example ones because it ends in letters and not numbers. Other than that I can’t thing of anything else it could be.

    Any help would be appreciated.

    I bought a used unlocked iPhone 1st gen 2g, and know NOTHING about iPhones and thinking I was deleting the prev owners personal info, contacts etc…. I deleted everything! So I went a googling! I was able to “restore” from iTunes but now it wont do anything but show the apple icon and the iTunes connected icon and slide for emergency calls. I have tried EVERYTHING I could find and so far cannot get quickpwn, redsn0w, blackra1n, or any of those types to open on my pc (vista) Redsn0w opened but when I selected the restore ipsw file it says unrecognizable every-time (and I have downloaded many of them). What can I do? I hate to have just wasted $$ for a stupid mistake (I really could kick myself).

      okay, this has happened to me. just plug in your device and jailbreak with redsn0w after you do a fresh restore. this will bypass the phone activation screen.
