These are instructions on how to jailbreak your iPhone 3GS on the 3.1.2 iPhone firmware using RedSn0w for Windows. If you are already on firmware 3.1.2, do NOT update to firmware 3.1.3. The Mac version of this tutorial is here. The 3G version of this tutorial is here . The 2G version of this tutorial is here

This tutorial can be used to jailbreak before applying the BlackSn0w unlock if you are on OS 3.1.2. You can find instructions on how to apply the unlock here.




Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here and place it in the Pwnage folder. Likewise, download the latest 3.1.2 firmware from below and place it in the same folder.

3.1.2 (3GS): iPhone2,1_3.1.2_7D11_Restore.ipsw
How to Jailbreak Your iPhone 3GS on OS 3.1.2 Using RedSn0w (Windows)

Extract the RedSn0w executable from the zip file to the Pwnage folder.

Step Two
***If you are running iPhone OS 3.1.2 you may skip this step***

Connect your iPhone to the computer and launch iTunes.

Step Five
Select the firmware ipsw we placed in the Pwnage folder on our desktop then click Open

Step Six
RedSn0w will ask you if this is a newer (fixed) model iPhone. Newer models of the iPhone 3GS have a fixed bootrom which requires you to connect your device to the computer each time you wish to reboot.

To find your serial number you can follow these instructions. The week number is usually the 4th and 5th digit of the serial number. For example, a serial number beginning with 88926 would be week 26 of 2009. 3GS units made week 45 or later will usually have a fixed bootroom. Before week 40 they usually have the older bootroom. Between weeks 40 and 45 the results vary.

If you believe your device has a fixed bootrom then press the Yes button. Otherwise press the No button.

If you accidentally select the wrong option you may have to do a full restore so please make this choice carefully.

Once the firmware has been verified click the Next button to continue.

Step Seven
Make sure Cydia is selected and click the Next button.
From this window you can select the jailbreak options you would like. If you have already pwned your device check the Already pwned option.

Verbose boot displays detailed information on boot of your device and is generally only needed by developers and advanced users.

Make sure Cydia is selected. For this tutorial we will also select Custom boot logo and Custom recovery logo.

When you click to select each custom logo option a dialog window will appear asking you to select the image. Locate the image you would like to use then press the Open button.

*Remember the rules for boot logos are: RGB or Grayscale format with Alpha channel and dimension below 320x480. If you would like to use the iClarified ones they can be found here: Boot Logo, Recovery Logo

Click the Next button to continue

Step Eight
RedSn0w will now instruct you on how to put your iPhone into recovery mode. Disconnect you iPhone 3GS from the computer then power it off. Then hold down the Home button while reconnecting the device to the computer. Don't let go of the button until RedSn0w detects the iPhone and begins installation.

Step Nine
Your iPhone will now reboot

Step Eleven
Once this is complete you will be notified that RedSn0w is done. Click the Finish button. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.

Is it true that if I currently have OS 3.0.1, I won't be able to upgrade to 3.1.2? I tried to JB and kept getting the 3194 error when I tried to restore to 3.1.2. What's the way to upgrade??? Do I have to wait until someone come up with JB 4.1 in order to upgrade my OS? Please advice. Thank you so much.

Awn - September 12, 2010 at 12:58pm
if you have never jailbroken, then now is NOT the time to jailbreak, you have to wait till 4.1 is jailbreakable.

Quick question, i am currently running a jailbroken 3gs with 3.0.1. I want to update to 3.1.2 but not 4.0.1/ I tried to do the shift click restore method, but it wouldnt take. probably because i never had this firmware installed in the first place. is there any way to install a specific firmware, without updating to the curent one and backtracking? thanks
Awn
Awn - July 25, 2010 at 1:41pm
if you have not backed up signatures for your phone, i highly doubt you could upgrade to 3.1.2/

Dear Team, i have been observing all the post in regards with jailbreak iphone 3GS but it seems that thre is something still to be explained or provide a little bit guideness as i know those who have 3GS (old botroom) are experiment some issue at the time to restore the IPSW created by the software...it seems that apple constantly refuse to update with the firmware...i am been trying to do everything according with your guideness but i can not get through to unlock or jailbreak my iphone 3GS (old botroom) I would like to ask a simple question; why it is that when you finish to create the IPSW with Redsn0w or Pwgnage tool this IPSW when you are using Itunes does not upgrade that IPSW, why is keep giving an error message? your response to his inquiry will be highly appreciated.

Ok this is frustrating....I followed step by step based on this tutorials. After I restore the firmware 3.1.2 and install the redsnow all I see is the completely black out screen nothing comes up and I cant power on/off ...NOTHING. But when I connect to the Itune it says im in the recovery mode but you cant really see it because the screen is black. Anyway, I have 3GS 16gb and if anyone experience the same please share. Thanks in advance.

The same problem , any help ?

Awn - June 30, 2010 at 12:30am
i have not experienced it, however; i could think of the following: 1) try the procedure on a different pc, with a freshly downloaded FW and redsnow, 2) try restoring 3.1.2 then balckrain it, just to see what happens 3) if all fails and you have an OLD bootrom, try OS4

I read the link that someone metioned below but i dont understand this ..how did you add this anyway ? " So, open the file C:\Windows\System32\drivers\etc\hosts (Windows) or /etc/hosts (Mac OS X) and add the following entry to the bottom of the file. 74.208.10.249 gs.apple.com "
