  • [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 think we are setting ourselves up for disappointment if we expect the stupid questions not to happen.

      In this case, stupid questions are the ones that get asked despite some great documentation. Careful research can save fits of fear and aggravation all around. Follow these guides carefully and you will do OK. Good luck and if you have questions after reading everything, the community ois very supportive and will answer it all. Above all, don't panic. Many have done this before and we are here to help.

      Anyone install Mobile Substrate and then try opening iTunes to purchase a song? It doesn't work. If you uninstall Mobile Substrate it works again.

      Somebody help me!

      I open redsnow and hit browse then click on the firmware file. iphone1,2blahblahblah.ipsw. It shows it as a zipped fil and when I click on it to select it as the file to open, it says "No searches matched." Showing an empty folder.


      If I try to extract the files from the folder it pops up messages saying that a file already exists under that name.

      What am I doing wrong?

      I have been having issues getting the firmware via ZIP files since yesterday. I've extracted two and neither worked. RedSn0w didn't recognize the firmware when I found it. I also tried to restore my phone to the firmware and it gives me an error via iTunes.

      I am having the same problem. If I extract zip files I get a bunch of different folders. What am I doing wrong? Thanks again for any help

      you need to use firefox and click on the links in the directions to use redsn0w if u use firefox it will not download into a zip file hope that helps, but i will also add if u use swirlymms to mms message do not use redsn0w or any other jailbreak because swirly has not updated to 3.0 OS yet wish i would have known before going to 3.0

      Yes but when I download via Firefox it sets the downloaded file to automatically open via iTunes. What should I change that to? What program should I open redsnow with.

      Im so confused. Maybe I'll just try IE or something.

      well that sucks it must not work for 3.0 then but i will say when i updated to 2.2.1 it worked but took a reasonable amount of time to do so!

      can you just save the file to your desktop and extract using winzip or whatever you have?

      I am computer illiterate. I have no clue wtf Winzip even is.

      I just want the damn files to open so I can jailbreak the stupid phone. I'm starting to think it isn't even worth the trouble. 3 hours and I can't even get the programs downloaded.
