  • [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!

      SO i did everything right.. but maybe i messed up along the way on something!

      after i jailbreak and everything goes good.. do i restore the phone again using my back u files?? it says that i would need them later on! also
      i logged on to a Wi-Fi and thought i was gonna be able to get on cydia when i log on it keeps timing out for some reason!! and sometimes it wold just go back to home screen. the signal was more then 50% and then when i tried to log onto the app store wouldn't log in..i've logged in before so it remembered everything but still didn't log in. besides that i went to safari and still nothing...

      Let me know any feed back or if any one else is having this problem! PLZ thanks!

      when i DL everything i put it all i the redsnow file! makes it so much easier to find it. so before you start redsnow put the

      iPhone1,1_3.0_7A341_Restore.ipsw
      along with
      BL-39.bin
      BL-46.bin
      and when i mean the redsnow folder is just open the first folder that on ur desktop and put it in there don't put it where the exe. is!

      Well did you try deleting it off you computer and then re downloading it..maybe it could be cuz your using vista or are you downloading it with firefox? maybe that could be it!
    1. mike2001ny's Avatar

      u dont need to redownload. even tho its rar or zip, just rename the extension from .rar or .zip to .ipsw then the icon will change

      Help please...I have Iphone 2G 8gb, Itunes 8.2, Windows Vista Ultimate SP2 I am currently logged in as the Administrator, i even selected run as Administrator on Redsnow but still doesnt work for me. I have the correct .ipsw file (iPhone1,1_3.0_7A341_Restore.ipsw) and the bootloaders all downloaded using Firefox. I get to the last part of the redsnow where its says DONE but my phone just wont boot open. Its stuck in the background trying to boot up (dim light). Ive restarted my pc and restored from itunes several times Any other suggestions? I dont have any other computer btw.

      Thanks DevTeam and OP for redsn0w and this excellent guide.
      I now have my 2G iPhone JB and unlocked on FW 3.0.

      The only issue I had was "Restoring" to FW 3.0 through iTunes. I would always get an error after about 5 mins (can't remember the code). I got around that by restoring to FW 2.2 then after that completed successfully attempted a restore to FW 3.0 again. this worked and I could then use redsn0w to JB/unlock.

      I guess I should have put the phone into DFU mode before attempting the restore. So thanks also to blkcadi for his post (quoted below) - I will remember this for next time.

      Cheers, Phew72.

      INSTRUCTIONS
      Step 1. Turn off iPhone

      Step 2. Hold down the power and home button.

      Step 3. When you see the Apple logo, release the power button but continue holding the home button down.

      Step 4. Open iTunes and wait for it to tell you that itís in restore mode.

      Alternative Method:

      Step 1. Connect iPhone to USB then listen to the sound when it connect and disconnect.

      Step 2. Hold the home and power buttons until hear the disconnect sound then release power button.

      Step 3. Wait until you hear another sound then release home button.

      Seems like moving it to another PC with a fresh install of iTunes and a new USB port all worked well = now unlocke and activated.

      Seems like its just moody on Vista!

      Thanks for an awesome app @ dev team.

      Thanks so much for the excellent step by step guide. I was able to JB and unlock my iphone 2G. However, I encountered one problem. I noticed that my signal has only one bar. When I checked the settings of my iphone it says that Carrier and Network is "not available". Can someone please help? I would really appreciate it.

      Thanks.
