HOW TO JAILBREAK IPHONE 3GS 6.1.3
Step 1: Before iphone 3gs jailbreak 6.1.3 download the ipsw firmware file for your iphone 3gs for iOS 6.0 Click Here To Download iOS 6.0.
Step 2: Download Redsn0w 0.9.15b3 or b2 both will work to jailbreak your iphone 3gsdevice. Click the download links for Win Mac. After the redsn0w 6.1.3 downloaded extract it preferably on desktop. Open the redsnow folder and run the redsn0w.exe file as administrator i.e. in Windows right click and select Run As Administrator and in OS X Mountain Lion, use Ctrl-Click => Open.
Step 3: Connect your iphone 3gs your computer and put it in DFU mode i.e. turn off your iphone 3gs and now press and hold both power and Home buttons for 10 seconds and after 10 seconds while holding Home button release power button and keep pressing Home button for further 10 seconds and release it.
Your 3gs screen will remain blank at the end and when you will open Redsn0w the status of your ipod touch will be shown in the middle bottom of redsnow window i,e Detected device iphone 3gs (DFU Mode).
Or you can perform this step later when redsnow will ask you to do these steps. Some people are confused at this stage and their iphone 3gs either becomes ON or goes in recovery mode, don’t worry just press and hold both buttons for a while and your device will reboot and you can try again.
Step 4: After the redsn0w program runs you will see the redsnow main window which is showing two options i.e. Jailbreak & Extras. Click Extras => Select IPSW when asked select ipsw file for ios 6.0 firmware file which you downloaded in first step. Browse your computer and locate and select to open. Nothing will happen at this stage only you will see a message that successfully identified with the build number in the message body. Click back to go to main RedSn0w 0.9.15b3 window again.
Step 5 : Click Jailbreak to go to next screen, you will see a quick message window saying preparing jailbreak data , patching kernel when asked ensure or select Install Cydia if not selected already = > Click next. If you have already put your iphone 3gs in DFU mode this step will complete smoothly and install the 6.1.3 jailbreak on iPhone 3gs and Cydia for 6.1.3.
You will see some messages on redsnow screen with progress bar followed by some activity on your iphone 3gs (first matrix text moving up and then RedSn0w icon showing progress for Moving applications) after which the device will reboot at the end.
After reboot if you check the springboard you will not find the Cydia or it will not run, this is because you have one step to complete the jailbreak and Cydia installation. The final step is boot tethered your ipod touch. If this was an untethered 6.0.1 jailbreak you would not need this extra step and jailbreak was complete.
iPhone 3gs Jailbreak 6.1.3 – Boot Tethered
Just complete the steps 3 & 4 and after selecting the 6.0 ipsw file go to Extras => Just Boot, if not in DFU put in DFU and wait until the screen activity is complete and your device reboots.
At this stage one may ask why we are selecting 6.0 firmware again but this is required otherwise you will face the error of “missing keys.plist”.
After you have completed the process, you iphone 3gs is now boot tethered and you will see Cydia installed on your 6.1.3 jailbroken iPhone. Enjoy.
