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. Someone please help! I have an iphone 2g. I used redsnow and followed step by step instructions. For some reason it seems to only be working halfway. I cannot access the home screen…only the emergency call screen and it says t-mobile up by the signal bars. I can make and receive calls. If a text comes in it pops up for just a few seconds then disappears…never to be seen again. I have been working on this for 3 weeks now and it is driving me insane.

  2. Just fine!
    Did exactly what I was told, it did exactly what I expected: I have it upgraded to 3.1.3!
    Thanks.

    (I had a unlocked/jail-broken 2G in iOS 3.1.2, if you wondered. I was skeptical to upgrade to this one. Out to install AmplitubeFree!! :P)

    1. YOUR LUCKY WHEN MY ONE SAID THE PHONE WILL DO THE REST MY PHONE JUSY WHENT WHITE THEN WHENT BACK TO NORMAL BUT IT STILL DIDNT WORK SO IF U KNOW WHAT I DID WRONGE PLZZZZZ COMMENT BACK
      🙂

  3. Hy all,i have Iphone 2G and i want sim unlock,and follows these steps.Every steps is okay,because in the end my iphone is stuck at " Downloading Jailbreak Data…" Screen, what i can do? (sry for my bad english languages)
    Somebody help me please! 🙂

    : in the end (after the "uploading ramdisk"),i can click on the finish button,but my phone is stuck in downloading jailbreak data.

    Thanks thanks!

    1. hello…
      i was also facing the same problem..but i finally have solved it….
      first of all download your desired firmware and it to a desired location
      then open your i tunes and put your iphone in DFU mode..(if you dont know if a DFU mode is searc on google) then itines will recognize your iphone in recovery mode..
      hold the shift button and click restore(while holding the shift key)
      browse to the place where you have saved your firmware
      click ok…the i-tunes will restore your phone and then you can unlock it using redsnow or blackr1n…hope it help you….thanks

  4. Notice all these instructions on the Internet have some sort of a flaw. This one says download redsn0w 9.3 and Firmware 3.1.2. That is fine. But if you look at the dialog boxes here you will see that redsn0w 9.2 is running not 9.3. Which is the right one remains to be discovered. I have tried both and have not been able to achieve what these instructions say I can.

    I would be happy, now after weeks of frustration, to simply ship my iPhone to someone, pay their fees and get this done and over with.

  5. Hi I have iphone 2g and wanted to unlock my sim but when I was running redsn0w at the beginning where you have to browse for the 3.1.2 update it stood "Unable to recognize specified IPSW" when I was browsing the right file! please help mee!!!!!

  6. Followed your steps got right to the end when it says waiting to reboot and i waited about an hour and it still did't work.
    Any ideas If you do PLEASE COMMENT BACK!!!!!
    THX..

  7. WHEN IT SAYS THAT THE PHONE WILL DO THE REST HOW LONG DOES IT TAKE COZ MY WHENT WHITE THEN WHENT BACK TO NORMAL SO IF U KNOW WHY THIS HAPPEND PLZ COMMENT BACK
    CHEERS 🙂

  8. I just followed these instructions and it worked perfect!! I didn't use the bootloader files from above link, found them elsewhere…But IT WORKED!!!! Thank you soooo much…first time I've ever done this:)

  9. so i did everything and i've done this 4 times with different websites and ive done the same exact thing. my iphone 2g, 3.1.3 version (win) is unlocked and everything except on my phone it says "no sim" even though i have it in there.

    does anyone know what may be wrong? i have a tmobile sim card

  10. So when i follow all these instructions, it should take the iphone to like where i can get to the music and everything? What if it says connect to iTunes? Then what?1 HELPPPPPPPPPPPPPP<3

        1. Good thing you mentioned AT&T Go Phone – All you have to do is call AT&T and ask them to enable your SIM card for iPhone 2G. That is what I did for my sister's iPhone 3G. So call them and request them. If they give a hard time, try again, trust me it works!

          p.s : You should disable data yourself, you can use SBSettings via Cydia for that…

  11. Kiran,
    thanks for writting one of the most sensible manual on jail breaking. I have a 2nd hand iphone 2g which I purchased from ebay. Before I proceed with the above steps, I have the following queries & will appreciate if you can help solve them
    1) will I be able to sync my iphone with itunes AFTER I folllow all the above steps.
    2) If not, how can I deete the existing contacts & manage my iphone apps?
