  • [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!

      I'm new so cut me a break, please. I jailbroke and unlocked my 3g when yellowsn0w came out anf it was working good on fw 2.2(5G77) I think BB was 02.28.00 I'm with tmobile service. well today I got a wild hair and read the start of this post and was going to ungrade to 3.0 redsn0w and unltrasn0w. I downloaded all that was listed and opened itunes and shift / restore and opened the 3.0 file that i had downloaded. when I was restoring about 75% in i got "An unknown error occured (10)" showed up. Was I to upgrade to 3.0 or restore? I know I'm a DUMMY so please be kind and help me, you'll feel better knowing that you did... Thanks

      Why do you want to put the phone in DFU? There are instructions at iClarified.com but just wondering why you want too?

      Are yo manually trying to put it in DFU mode or do you mean Redsn*w won't put it in DFU mode for you??

      I've never had this problem. I have had where windows would say redsn*w stopped responding. In this case, I usually just have to restart my PC and it works. As far as having trouble putting it into DFU mode, never had an issue. As you following the sec's count closely?

      Also, I usually take the SIM Card out when jialbreaking. I'm not sure if it makes a difference or not.
