Jailbreak and Unlock iPhone 2G With 3.1.3 Firmware Using Redsn0w

Written By Sam on 3 February 2010

Apple released the 3.1.3 version (7E18) of the iPhone OS which updates the baseband of iPhone 3GS and 3G to 05.12.01. There were no tools available until now to jailbreak and unlock iPhone 3G/3GS with 3.1.3 Firmware. Even if you have different models of iPhone or iPod Touch it is better to stay away from latest iPhone OS 3.1.3.

If you have accidentally updated your iPhone 2G to 3.1.3 firmware, you can still jailbreak and unlock it as the baseband of iPhone 2G is not changed with the latest 3.1.3 firmware. Below is the procedure to jailbreak and unlock iPhone 2G with redsn0w.

How to jailbreak and Unlock iPhone 2G With 3.1.3 firmware using redsn0w

  • Download the latest version of iTunes and update your iPhone to the latest 3.1.3 Firmware if you haven’t already done it.
  • Download redsn0w 0.9.3 for Windows or Mac based on your OS and also download iPhone OS 3.1.2 IPSW file(Yes we need a 3.1.2 firmware also!).
  • Now run redsn0w and browse to the original iPhone OS 3.1.2 .ipsw file(Be Clear, it is iPhone 3.1.2 IPSW and not 3.1.3). Redsn0w will check if the firmware is valid and will then patch it.
  • As we are using a iPhone 2G, we need to select “Install Cydia” and “Unlock” to unlock your iPhone 2G.
  • If you are interested in customizing your iPhone you can choose any/all of the “Custom boot logo”, “Verbose boot” and “Custom recovery logo”, else you can skip this step.
  • Now redsn0w will show you some instructions to enter into DFU mode.
    • Hold down the “Power” button and immediately without releasing the power button, also hold down the “Home” button. Without releasing the “Home” button, release the “Power” button but keep holding the “Home” button for 30 seconds.
  • Your iPhone will reboot once it is jailbroken
  • Once you are done with jailbreaking your iPhone 2G on 3.1.3 firmware you can unlock it by using BootNeuter app from Cydia.

We are warning you again that this 3.1.3 Firmware jailbreak is strictly for iPhone 2G old models. If you have got an iPhone 3GS/3G or iPod Touch 3G/2G newer model do not attempt to upgrade your firmware to 3.1.3.

    I cant browse to the original iPhone OS 3.1.2 .ipsw file which is on my desktop! It doesnt show up when i browse it!

  2. julia says:

    Yes and I put the 3.1.2 folder on my desktop when I downloaded it. When I then started the redsnow and wanted to browse the 3.1.2 folder it didnt show up, and no one of the files are ipsw files.
    Maybe that is the problem?

  3. connor says:

    I f im upgrading from my previously Unlocked 2g, then how is it possible to use Bootneuter to unlock via cydia…Surely i will not be able to connect to cydia and install B/N if my phone is NOT NOW unlocked and wont accept my sim card.

    Im on orange etwork just now but if i update with redsnow will i be locked back to 02??? How can i install bootneuter if my orange sim is not accepted..Please any help appreciated

    • Sergio says:

      Well i have an 8 GB 2G iphone running 3.1.3, I unlocked it and jailbroke it at the same time with redsn0w. After jailbreaking it will automatically go into bootneuter and do its thing.There is no need for you to do anything. Once redsn0w is running, and in about ten mins youll have an activated, unlocked and jailbroken iphone 2G.

      • Minray says:

        what if you already jailbreak with cydia.

  4. ela says:

    i accidently up updated my iphone 3gs 3.1.2 to 3.1.3(7E18) as soon as you details on to jailbreak please email me thanks

  5. julia says:

    Which file am i suppose to browse??

    • Samrat P says:

      You need to browse the original 3.1.2 firmware for your model. Just download it from the web.

      • julia says:

        But it doesnt want to browse the whole folder.. just each file, and when i tried to browse a file it said that redsnow was unable to recognize specified ipsw file..

      • Samrat P says:

        You need to browse just a single 3.1.2 ipsw file that you have downloaded from the net. If that is the correct file then redsn0w will validate it and then patch it

  6. julia says:

    non of these files could be browsed… i btw changed all files to ispw. manually because they weren’t in that form when i downloaded the firmware

  7. Dan says:

    Did this twice and seemed to got through the process normally, but it did not put the Cydia icon on the phone. Not sure what to do now?

  8. REMFAGE says:

    Upgraded to 3.1.3 and unlock…

    thanks a lot……

  9. chinarep says:

    I was just given a 2G today and accidentally downloaded 3.1.3 but followed everything Samrat P said and it worked just fine. Make sure you download 3.1.2 ipsw file and possibly need 3.9 and 4.6 binary downloads. Then follow the screen. took me twice to get the power button and home button steps but then worked perfect.

  10. dominic says:

    Ran redsn0w0.9.3, pressed “browse” iPod2,1_3.1.2_7D11_Restore.ipsw, Is it MC Model? I pressed NO. Checked Install Cydia, Verbose boot. Pressed next and I’m stuck where it says “Please connect your device in Recovery Mode” I know what recovery mode is. I can’t press Next >

    =[

  11. Lauren Williams says:

    I have a iphone 2g that i bought from a friend and she had it recently upgraded to the 3.1.3 firmware. i got thru the jailbreaking process just fine, the cydia app shows up in my apps, but i go thru cydia and can’t find the bootneuter app!

    Appreciate advices. Thanks

  18. Cb says:

    yes .. did that several times .. redsn0w successfully identified the iphone1,1_3.1.2_7D11_Restore.ipsw. Once it reaches “preparing ramdisk”, it issues error message when “preparing ramdisk”

    I run the program and click “Finished”, and then the window closes, and my device is off. When I turn it on, Cydia is nowhere to be found. Help?

  21. John says:

    I tried to download the 3.1.2 ipsw file from multiple locations, and after I extracted the files from the compressed folder, there were no ipsw formatted files within the folder. I tried downloading from alternate sources from the web, and the same deal. Is there anyway anyone can tell me why this is, or simply email me the ipsw file as an attachment to bsuplaya@sbcglobal.net. It would be greatly appreciated. Been battling this problem for a month.

  22. gwava says:

    I had a lot of trouble updating my iphone. The first time I jailbroke it no problem but when it finished the phone got stuck in a reboot loop. I put the phone in DFU mode but itunes had a really hard time recognizing it (getting the DFU timing just right is VERY important). I connected the iphone through a USB hub which seemed to work. Right now I am just trying to rejailbrake (after probably 5 hours) that I will try to unlock it after. I think choosing to install cydia and unlock at the same time isn’t working.

    Hi,

    I have an apple iphone 2G running which accidentally got upgraded to 3.1.3. It was a jailbroken and unlocked iphone and now it is stuck at the ’emergency’ calls only screen. I am able to make and receive calls but nothing else works. When I connect to itunes it says that the ‘sim is incorrect’. Could someone kindly guide me as to what shall I be doing in this case. I tried the above mentioned steps but redsn0w 0.9.4 says ‘rest of the process takes place on your device’ and my iphone screen goes blue for sometime, reboots and comes back to the previous ’emergency calls’ screen. Please help!!

    Hey there.,
    i have an iphone 2g (and live in australia) that i baught unlocked and jailbroken in singapore. i found a websight and upgraded the firmware to 2.2.1 a while ago…

    so if i want to upgrade this firmware to 3.1.3, do i follow this entire procedure? the reason i ask is because you say that this procedure unlocks and jailbreaks when my iphone is already both of these?

    • jas says:

      First, you need to restore the 3.1.3 ipsw from itunes. Once updated, your device is non unlocked and jailbroken anymore. Therefore, you need to use redsnow to unlock and jailbreak it again. There, your 3.1.3 unlocked and jailbroken successfully.

      Hope this helps 🙂

    I have a 2G with 3.1.3. If I unlock it using redsnow, will I be able to use the iphone with Tracfone? There are two issues: 1) they always ask for the SEI as well as SIM when adding service, and 2) the phone displays minutes & cal time left before buying more time.

    Hi Suresh. You need to put in an AT&T SIM card and activate the iPhone with iTunes.

  36. Big Mike says:

    I spent the weekend working on this. I have an iPhone 2g and I jailbroke and unlocked it following your instructions. I have done it numerous times but each time i insert a working at&t sim card either it locks me out (connect to iTunes or call for emergency) or it never finds the network. It stays searching. Any suggestions? I have restored and re done many times

  37. Cristiano says:

    Can someone tell me whether if I could use a SIM from another network after jail broken?.(not AT&T).Cos im outside USA?
