  • [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!

      Now i have to install the Cydia Apps only
      I just found this site, my bro gave to me, i'm having problems with my unlocked/jailbroken 2g iphone.. so you had ur's alrdy jailbrkn/unlocked and when u upgraded to 3.0 it stayed that way?

      I restored to 3.0 successfully. The only glitch is that it won't connect to wifi automatically. I have to manually go into settings and choose my wireless ssid manually every single time! Very annoying. Anybody experiencing this? Any ideas?

      Hey Guys
      thanks for all that time you invest to help us und bring us tools like redsn0w and so on.

      Unfortunately I got some probs with redsn0w
      After updating my iPhone 2G to firmware 3.0 via iTunes (version 8.2) I quit iTunes in order to use redsn0w.

      Following the instructions step by step I entered DFU-Mode. No probs till here! The first and the second step after entering DFU-Mode seem to work, but after those the tool gets stuck waiting for reboot (more than 10 Minutes). To make it clear: this is the second 'Waiting for reboot' after entering DFU-Mode.

      The phone doesn't do anything while redsn0w waits.
      After quiting redsn0w the phonescreen stays black and the only way to bring that brick back to life is restoring via iTunes

      I tryed several times and downloaded all files again from the opening post of this thread but its always the same problem

      I'm using Windows Vista Business x64... Is it necessary to run redsn0w as admin??

      Did I do something wrong??
      Has anybody an idea how to solve this??

      Any Help is appreciated!!
      Thanks

      This worked fabulously on my iPhone 2G 16GB.

      Just one little question. I have a 1G 4GB phone that I would like to unlock. I am under the impression this phone is infact a first gen and my 16 GB is a 2nd gen... is this right? Will RedSnow unlock the 1st gen phone too?

      doesn't matter what size it has 4,8,16 gig, it's still 1st gen iphone, 2nd gen gsm standart, it means supports EDGE. this is nothing to do with iphone but network. other than 3G and 3G S, all of them actually 1st gen iphone but 2nd gen GSM or cellular network...

      Like many other people here, everything with redsnow worked fine until the very end, when it froze on me, showing a little loading icon at the bottom.

      Now however, the pc wont recognise my phone at all! How am i supposed to attempt to unlock my phone now?

      you'll have to put the phone in DFU mode/restore to a fresh copy and start the process over. Good luck

      make sure you know where you saved it so when you run redsnow you'll know where to locate the file
      Correct I'm using IE......I've always use IE to download the firmware file with no problem (Granted I've always used Quickpwn). How all the sudden would the browser make a difference?

      Ok, I have something to add to the list of issues being encountered:

      I am able to update my iPhone 2G to 3.0 OS using iTunes, and then able to follwo the steps in redsn0w - the phone responds right up until the last reboot where it displays a solid white screen and redsn0w indicates that its done...what does this mean?

      It does not recover from this condition even after 15mins - strange - only way to get it back is to switch the phone off after which i get the activate emergency screen. Prior to this the phone was unlocked and jailbroken using QPwn 2.2

      Any help is appreciated.

      "Unlocking" allows you to use it on other carriers (like T-Mobile). So yes, you need to do it.
