  • [Windows] How to Jailbreak and Unlock iPhone 2G Firmware 3.0 with RedSn0w
    This guide will teach you how to jailbreak AND unlock your iPhone 2G running 3.0 firmware using RedSn0w on Windows.

    I strongly recommend you backup and restore your iPhone 2G 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 2G 3.0 firmware file available for download here. You also need the 3.9 and 4.6 bootloader files. Download 3.9 here and 4.6 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.



    Find your iPhone 2G 3.0 firmware file you downloaded earlier. Select it and click Open.



    RedSn0w tells you that the ISPW is successfully identified. Click Next.



    There will be a quick pop up.



    Select your options to Install Cydia and Unlock. If you don't need to unlock your iPhone 2G you can de-secelct Unlock



    If you are unlocking you need to located the 3.9 and 4.6 bootloader .bin files you downloaded earlier.









    Now that you have told RedSn0w where the bootloader files are click Next.



    At this point you should make sure your iPhone 2G is plugged into your computer AND turned 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 and Unlcoked. Don't mess with your phone while all this is going on. After your phone restarts you are done!

      Did you have your SIM in the phone when you ran RedSn0w?

      The usual cause of this is downloading the wrong FW or FW from 'dodgy' sites'
      Links to the FW direct from Apple can be found at iCommunity - Jailbreak information at a glance - download the FW from there and try again.

      OK, I do not know what I am doing wrong.

      I had a friend unlock and jail break my ipgone 2G on two different occasions with issue. He even gave me the program so that I could do it myself.

      Now that I have tried to do it myself, I can not get it to work.

      My problem is that it hangs on the bootneuter 2.1 install. I dont know where this program is coming from, as it wasnt there when my friend did it.

      I have tried about 4 or 5 different times to unlock and jailbreak it, and each and every time it hangs on the bootneuter....

      HELP!!!!

      Well, I finally figured it out...

      I used itunes and iPhone1,1_3.0_7A341_Restore to UNLOCK the Iphone. I then used redsn0w-win_0.7.2 to Jailbreak it.

      The problem I had was, I was using redsn0w-win_0.7.2 to BOTH unlock and jailbreak and it was trying to also install bootneuter 2.1 which was freezing.

      Somehow using itunes with iPhone1,1_3.0_7A341_Restore to UNLOCK and then using redsn0w-win_0.7.2 to jailbrake, it doesnt try to install Bootneuter.

      So there ya have it... Saved myself 35 bucks... Now to restore everything......

      I've done everything said, and it been perfect but in the step where I have to turn off my phone, it's not working. It's not turning off or going on DFU mode

      I've had my 2G iphone jailbroken and unlocked using redsnow (3.1.2) for months now. Yesterday I did the Cydia update that popped up but it gave me an error. I cleared out of Cydia and did a reboot using SBSettings.

      Since that point I've just had the pineapple on my screen and my phone won't actually make it to a usable spot.

      I'm not sure how to get it into DFU mode for a re-jailbreak.

      Any suggestions?

      Worked perfectly on my 2g, I followed these steps:
      - Got the firmware 3.0.
      - put phone in DFU mode with ITunes Running, it said phone in recovery mode.
      - shift-click restore selecting your firmware 3.0
      - when done, ran redsn0w and your steps.
      - That is it.
      - During the unlock, bootneuter ran.
      - Phone is unlocked now no errors.

      Thanks for the steps.

      LOL! I think it's funny to see uber old threads get the bump.

      Shiva, you should get 3.1.2 since iOS4 isn't supported for first gens.

      Actually nothing. I remembered reading though the dev team was working on a way to get iOS4 onto first gen iphones. If they do, chances are it would work the same way for 3G and 3GS.

      He/She would need to be on 3.1.2 jailbroken

      You don't need to be JB on a 3G to JB/Unlock iOS4
      You certainly won't need to be on a 2G - but AFAIK no one on the Dev Team is working on iOS4 for the 2G

      Without knowing what phone and FW and what you have used it is very difficult to advise.

      Has anybody recently and successfully jailbroken/unlocked an iphone 2g (1st gen) for use with AT&T prepaid sim?

      I have done everything with blackra1n and redsn0w. I have the cydia app and bootneuter app on springboard. I really think the phone is jailbroken and unlocked but I keep getting the no service message....

      I did all the jailbreak/unlock with the already activated prepaid SIM in the iphone.

      What else am I supposed to do? Or will this work at all??

      I am desperate now. lol
