Jailbreak and Unlock iPhone 2G OS 3.1.3 with Redsn0w

3 February 2010 by Vinay 19 Comments

Apple unexpectedly released a firmware 3.1.3. With this new release, Apple update the baseband of the iPhone 3G and 3Gs and as usual the iPhone 2G baseband is unchanged. You can do this guide on any iPod, and on the iPhone EDGE aka iPhone 2G. Procedure is same like you jailbreaked your iPhone 2G 3.1.2 with a little change described below.

Download for iPhone Jailbreak

Windows Version
Mac Version
iPhone OS 3.1.3 Download Here
iPhone OS 3.1.2 Download Here

Step 1. If you have not already, download the original firmware 3.1.2 and 3.1.3 on the desktop of your computer. In case of unlocking an iPhone EDGE, be sure you also have the two files Bootloader: bl39.bin and bl46.bin

Step 2. Connect the iPhone to PC or Mac and update your iPhone 2G to firmware 3.1.3

Step 3. Launch the application and click on Browse. Select the original firmware 3.1.2 [select 3.1.2 not the 3.1.3] from the desktop of your computer and then click on Next

Step 4. It will start an automatic process (and very fast) which will be downloaded and patched the kernel.

Following a new screen will appear. Cydia is already selected.

Install Cydia: Main reason why we jailbreak iPhone.
Verbose Boot: Will allow you to replace the boot with the apple (boot chart) with the verbose mode, or the ability to see everything that is loaded at startup;
Custom Boot Logo: Bore with classic apple startup, change with your face or whatever else. Size should be 320X480.
Recovery Custom Logo: A logo that will replace the classic Recovery;
Already Pwned: Select if you want to install the verbose boot or change the boot and recovery logos on an iPhone on which has already been to jailbreak;

Step 5. Now you will be asked to put the iPhone in Recovery Mode (iPhone 3GS) or DFU (the other iPhone / iPod).

How to put your iPhone in recovery mode :

Turn the device completely off and disconnect it from cable/dock.
Hold down the home button.
While holding down the home button connect to a computer with a cable (easiest) or dock.
Keep holding down the home button until you see a connect-to-iTunes screen You are now in recovery mode.

To escape Recovery Mode and power the phone off simply hold down power and home buttons for ten seconds.

How to put your iPhone in DFU mode :

Connect your iPhone to your computer.
Turn iPhone off.
Hold power and home together for 10 seconds (exactly).
Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
A few seconds later iTunes should detect your iPhone.
If the Restore Logo is present on the screen, you are in Recovery Mode, not DFU.

Step 6. Once you are in recovery mode/dfu mode redsn0w will start another automated process to complete the Jailbreak.

Hi, I had an iphone 2g 3.1.2 – i used blackra1n, cydia, and bootneuter. I jailbreaked. But after I ran bootneuter it said TMobile in the corner but only said “Connect to Itunes”. I then connected to itunes to restore it, but accidentally upgraded to 3.1.3. My baseband is 04.05.04, and when I put the Tmobile card in it still says TMobile in the corner and “Connect to Itunes”. WHAT DO I DO NOW??? RUN BLACKRA1N AGAIN? OR RUN REDSNOW?? PLEASE HELP!

Whenever I download the Ipsw files and extract the Zip I don’t ever get the actual ipsw, just a bunch of .dmg and a couple folders. Any ideas on what I do?

I’m using iPhone 2G OS 3.1.3

Can anyone please help? I have a 2G and followed the instructions however in redsnow it asks to hold down power and home until that message goes away, which I did (instead of the DFU instructions here).

The problem is that the phone is still not unlocked *wails* and I don’t know what to do. I tried following the DFU instructions too, but it just loaded up in itunes as recovery mode and redsnow didn’t continue on at all.

I am satisfied with your idea. But I lost the carrier section in network menu, that’s why I am not able to activate any sim card in iphone. What will I do ? Please suggest.

Thanks.
