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!

  2. I just bought this iphone 2g off ebay.. had a broken screen and i replaced it.. umm.. stuck on needing to activate it.. figured this would work.. but not sure what the firmware is.. can anyone help?

  3. hi, i just followed ur instruction and surprisingly it really works and i really thank u for that…these past few days i was so excited i kept on using my phone but i only noticed one problem… how do i desactivate the internet connection coz it's eating up my load since then… i would really appreciate if u can help me please
    my iPhone 2G version is 3.1.3(7E18) [just what the redsnow outcome],
    model MA712LL,
    modem firmware 04.05.04_G
    and i'm using Windows XP

      1. sorry but i'm not really good on this is there any exact app to download from cydia coz i'm only getting themes on mine…tnx again

  4. Followed the instructions exactly! THANK YOU SO MUCH i've been trying to unlock and jailbreak my phone for days using blacRa1n and various other methods….this one worked on the first try easily!

    THANKS YOU my Iphone 2g is now working under T-mobile =)

  5. Seems to have worked on upgrade, thank you. Now i'm working on mms. thank you very much this was an easy to follow guide, and it worked like a charm!

  6. ok I tried this, and it worked, kinda. my phone is now upgraded to 3.1.3. I don't have service anymore. I'm using a 2g iphone using 3.1.3 firmware. I'm wanting to get mms working on my iphone. Any help would be great. thanks again

    1. Let me clarify a little more. I was using 2g with 3.1 firmware on att prepaid service. I was needing to upgrade to 3.1.2, so I could enable mms on it. After doing the above, it is now upgraded to 3.1.3 and I have no service. I'm using windows xp pro. Thanks

      1. Nevermind. I don't know what I did, but it is now working. I went to try to restore to the file above. My computer shut down in the middle of the process and my iphone wouldn't do anything but show the connect to itunes logo. I restored to a new status, then followed the above thinking it wouldn't work and that I'd be back to where I was before my computer crash. Once the phone was completed, I noticed that I had service, and it is running 3.1.2. I sent a test message and it worked! Bad side, I lost everything except my contacts on my sim card, but since I'm still learning how to use it to its full potential, its not that bad *whew*.

        Thanks again, and any insights as to your interpretation would be great, but not necessary.

        1. Hi Greg. With iTunes, you always have to let it sync and perform a full backup just in case. That way, all your data is backed up at all times. Just connect the iPhone to your PC / Mac every now and then and you are golden! Congrats on graduating iPhone 101!

          1. yeah it gave me an option to restore to a backed up, but I didn't know if that would put me back to where I was before, so I decided to just lose everything and restart. Yeah it's a pain to put everything back on there, and I haven't learned everything about iTunes yet, but i'll get there. I've had this phone for about 2 weeks now and I'm still learning about it. It is very complex and very useful. Thanks again for the help. Greatly appreciated!

  7. I bought iPhone 3gs and for "x" or "y" reason Now is 3.1.3(7E18); firmware 05.12.01 (I installed itune 9 on XP operation system) and I don’t know what I need to do… to unlock… I am really new in this matter… is my first iphone, (I was very happy with Siemens SX66 but it was broken) I did not know about all this complication on iPhone… (I want to cry… hihihi) anyway I studied a lot about… but what I need to do exactly?, it is recommendable to reboot? In order to get the original 3.1.2 & 05.08 or whichever it had originally on my iPhone. (I don’t know which version had originally but on the box, the serial no is: 84946DN… I read that with 46 before D, is possible to know)… then with this action will be possible to install jailbrake? and Cydia? sorry for my TV soap opera… somebody could help me…

      1. Kiran: Thks so much for your answer… believe me… I am very new in this matter and I don’t know where I need to looking for this file…? Cydia is not inside of my iPhone now…? maybe I can not find the file on it…, or maybe exist some procedure to do it…? I mean install Cydia and looking for the SHSH file…

  8. Huurreeeyyy…!!!
    I have iphone 2G and was i strickly follow all procedure as given above with redsn0w 0.9.3 and all that stuff.Thanks a lot..Appreciate to all those who is working hard and passing technology.

  9. BRILLIANT!  So simple and worked perfectly.  thank you.  I was preparing for ages to get this done but these instructions were clear and simple!

  10. Hey. I followed what ever you said here.
    But when i selected the corresponding firmware on redsn0w, it says IPSW is not identified.
    I have a iphone 2g. Please help. 

  11. I have the same problem as Prateek. When I click and download "3.1.2 Stock iPhone firmware" there is no .ipsw file. Of course, I extracted the zip file. Also the link to redsn0w is not working for windows users. Ihave 2g iPhone too. I appreciate if you can help us. Thanks.

  12. Did you join the 2 files using hj_split? What is the exact filesize – 217MB? In Windows, you have to enable extensions for folders and then if you still don't see .ipsw, rename it… Let me know!

  13. Which 2 files? When I extract the 3.1.2 zip file there are three .dmg files in the "iPhone1,1_3.1.2_7D11_Restore" folder one is 217mb and the other two are 12mb. There are also 2 folders. Thanks.
