  • [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!

      okay so I thought I had 3.0 working great, using redsnOw to unlock my phone... but come to find out my phone was no longer receiving calls. It would alert me to voice mail messages but would not ring.... I have tried restoring to 2.2.1 but iTunes never successfully restores, I always get "error 20"...

      Any ideas???

      Yup, but your not gonna like it.
      Your going to have to start all over, sounds like a file got screwed up.
      Put phone in DFU mode, restore to a fresh copy of 3.0 and begin the process again. Sorry

      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.



      sry for quoting myself here, but i just wanted to show u the problem i had...

      anyways, i used another computer and it worked perfectly... dunno why, just try another pc with a fresh install of itunes 8.2... might work for u 2 hopefully...

      took your advise... i was first using vista to try to unlock/jailbreak 2g... many many tries.. it didn't work.. went to my other computer which is XP, download everything (iTunes 8.2, redsn0w, etc)

      restore with itunes, then ran redsn0w. work fine now.

      I just watched the vid, and yup he's doing it correctly, obviously it worked for him.
      Not sure what you missing. The most important thing is to have a fresh 3.0. If you fail, you have to DFU /re-install 3.0 form iTunes and begin the process.

      Before I do anything, does the iphone have to be in 3.0? or can it be 2.2 and still do jailbreak/unlock?

      So I put redid everything... I went back into DFU mode, used redsnOw, and every thing appeared to load fine. I even redownloaded all of the files just to be sure everything was okay with the files, but still I cannot receive calls, they go straight to voicemail. I can make calls... I would love to just go back 2.2.1 but when I try to restore iTunes gives me an error. I even uninstalled iTunes 8.2 just in case that was the problem with the "downgrade" but iTunes won't do anything with a3.0 phone if you don't have 8.2.

      How can I get my iPhone working again???

      ok I admit that I am feeling seriously rediculous right now. I downloaded the iPhone1,1_3.0_7A341_Restore.ipsw.zip and there is no ipsw file in it.

      Inside the unzipped folder is the following:

      .fsecentsd (folder)
      Firmware (folder)
      3 dmg files and 2 plist files

      Any help would be greatly appreciated.

      Note: Redsn0w0.7.2 is now available on the Dev-Team blog. No indications about what has changed.

      im pretty sure smothered that you change the file extension to ipsw by removing the .zip and putting ipsw. Either that or dl using a different browser. That should do it.
