Jailbreak, Activate and Unlock Original iPhone 2G 3.1.3 Firmware Using redsn0w [Windows/Mac]

Kiran Konathala • February 10, 2010 • 2 min read

Original iPhones (metal back, silver color, referred to as 2G iPhone) are blessed with a fully unlockable baseband 04.05.04_G. It entitles the iPhone 2G to be easily hackable. So lets get the ball rolling and get to the latest 3.1.3 firmware with a full unlock, jailbreak and activation in place!

Step by Step :

Download redsn0w 0.9.3 from downloads section and extract them to your Desktop [Both Mac and Windows versions of redsn0w are available there]

Connect your iPhone 2G to your PC/Mac and launch iTunes [Update iTunes to the latest version]

Update to 3.1.3 firmware directly from iTunes itself [Just click the update button in iTunes]

Meanwhile, download 3.1.2 Stock iPhone firmware and save it on the Desktop [Make sure it is .ipsw extension and not .zip]

Once the update is done, launch redsn0w 0.9.3 and click on browse button and browse to the 3.1.2 firmware that you just downloaded [Saved on Desktop] and click Next as shown. Follow the screenshots and proceed accordingly [Make sure Unlock and Cydia are checked]

Download the bootloader files for iPhone 2G. Extract the downloaded files 39.bin and 46.bin to the desktop.

When you are prompted for the bootloader files 39.bin and 46.bin in redsn0w , browse to the respective files saved on the desktop and click Next.

Now make sure your iPhone is connected to your PC/Mac and turn it off [Hold the power and slide to power off] and click Next.

Now follow the on screen instructions carefully, it is ok to miss those on the first try. Click back and try again [The 3 steps should as prompted should be done in the time shown on redsn0w].

Now let redsn0w do its thing! You will see some images on the iPhone which means it is jailbreaking, unlocking and activating your iPhone 2G! Wait till you see the homescreen, in other words leave the iPhone alone for few minutes.

Enjoy your jailbroken, Unlocked iPhone!

  1. Thank you so much. It worked perfectly. The problem was when I downloaded the file, it downloaded as a zip file and when I extracted it, there was whole bounch of wired files. But when I clicked on it and saved it as a .ipsw file redsnow recognized it. Really appreciate your help Kiran.

  3. Which two files? there is only one folder "iPhone1,1_3.1.2_7D11_Restore" in which there are three .dmg files. one of them is 217mb and other two are 12mb. there are two other folders too.

  4. I thought you were downloading custom firmware.

    In your case, it is a stock firmware from Apple. I think Windows was automatically extracting the file that you downloaded. Right click on the download link and click on 'save as' and save the file as .ipsw. Lets see if that works. If not, I will try to help you remotely. 

  7. Thank you so much!!! I t worked for the most part and your directions are by far the clearest directions I have read. I do have a couple questions though… I am using a unlocked for Tmobile 2g and upgraded (with your instructions) to the 3.1.3 firmware. Before upgrading I was able to get internet (which I pay for through T-mobile) but i no longer have internet. How do I fix this. Also I had mms where I could send pictures but I could not receive them. This feature has also went away. Is there any way to fix this problem?

    1. Hi Jasmine. You will have to input T-Mobile's data settings in -> Settings -> General -> Network -> Cellular Data Network. In the APN field enter wap.voicestream.com, leave the username and password blank.

      For MMS :
      APN: wap.voicestream.com
      Username:
      Password:
      MMSC: 216.155.174.84/servlets/mms
      MMS Proxy 216.155.165.50:8080
      MMS Max Message Size:
      MMS UA Prof URL:

      Click Home to save.

      Install Legacy:
      1) Open Cydia
      2) Search for Legacy
      a. You should have 2 results
      b. Install first result (T-Mobile US – Postpaid/F…)
      3) Reboot Iphone.
      4) Send yourself a test MMS

      Try it and let me know!

      1. Thank you. I was able to get internet again, but I do not have the option to even add the APN for messaging because that field is not there. When I went to cydia and searched for legacy it did not appear.
        Well at least I have internet again. Thanks!

          1. For this, you tell us to enter wap.voicestream.com into the APN field… I see two APN fields, one under Cellular Data and one under Internet Tethering, which one (or both do we enter this into)???

  8. I used this for T-Mobile and I can now call/text, which is great, but i am unable to get any data services (safari, email, facebook, etc) or a WiFi connection. I had a blackberry earlier today with internet so i know i have a data plan from T-Mobile. Can anyone help????

    1. I read the info provided above by Kiran, and it worked great for making an internet connection, HOWEVER I still dont have WiFi for some reason

      1. When did you lose WiFi capability? Was it working before you followed this guide? If yes, it is highly unlikely that your WiFi is affected. I suspect a hardware issue if the issue still persist even after restoring to a fresh 3.1.3 install..

  10. Process worked great. However I'm still getting "SIM Locked" message when I try to install my AT&T sim from my current phone. Is this something they can or will fix?

  15. This didn't work for me, i followed the instructions exactly. The iphone shows the harddisk and says: "Downloading Jailbreak Data…" Then it reboots and i get back to the same emergency call only screen. What could i have done wrong? Or what else should i try?

  16. Thanks Buddy, Your Instructions were awesome. I was able to Jailbreak and unlock my Original iPhone which had Version 3.1.3 with Modem Firmware 04.05.04_G. Note: Use redsn0w 0.9.3. The Next Version redsn0w 0.9.4 doesn't work for Original iPhone.

  19. I went through the entire procedure successfully, I thought. After everything was done, I shut off the phone, inserted a T-Mobile sim and started the phone again. All my icons are there, including Cydia. However, there is "No Service." I cannot use the phone. Help!

        1. OK, I found out on the web what to do and installed it through Cydia. Performed the flash successfully for both versions 3.9 and 4.6. Software appears buggy and freezes from time to time. Stays too long on "Determining current settings." In any case, the Carrier is recognized haphazardly. Sometimes the carrier is there and sometimes it is missing with "No Service." I cannot make or receive calls even when the carrier is visible. Is there a solution for this?

          1. I would try this guide one more time verbatim. Let us start from scratch with official firmware 3.1.3 as noted in the guide. Apple cares less about iPhone 2G baseband, so it can completely be unlocked… I am hoping there is no hardware issue in your iPhone..

          2. I tried it for the third time, and this time everything appears to be working just fine. I tested phone calls with three different sims on two different carriers and they all worked. Because I followed the same procedure religiously all three times, I do not understand why it did not work before. The Bootneuter was buggy during my second attempt and hung a few times. In any case, all is well now and I thank you very much indeed for all your help.

  21. I have jailbroken and unlocked successfully, and have no need for installing any applications through Cydia. Will I need Cydia again? I would like to uninstall it. Is it okay to do that?

  22. Hi, I was able to jailbreak using Balckrain but couldn't unlock it so uninstalled blackrain and cyndia and tried to unloack again using blackrain. This time my phone wouldn't jailbreak at all, tried multiple time but all the steps runs fine but when done there is no blacksnow logo on my phone.
    Can someone please help, I am stuck here for 2 days.

    PS: I have an iphone 2g 3.1.2 on 04.05.04_G
