Not too long ago I Jailbroken my iPhone 4 on the official iOS 6 firmware tethered and installed Cydia. If you would like to also Jailbreak your iPhone 4, iPhone 3GS, or iPod Touch 4G tethered on the iOS 6 firmware with Cydia you will be glad to know the process is detailed in this tutorial.
WARNING: Things are very buggy once you are Jailbroken on iOS 6 with Cydia installed. This becomes even more the case when you begin installing packages. I would strongly suggest waiting for the iPhone Dev-Team to release a stable Jailbreak that includes an official build of Cydia, but if you can’t wait then there is nothing holding you back. Furthermore, this is a tethered Jailbreak meaning that you will need to use your computer to boot your iPhone or iPod Touch every time it loses power or crashes.
Jailbreak iOS 6 Firmware [Mac OS X / Windows]
Step 1) The first thing you will need to do is update your iPhone or iPod Touch to the official iOS 6 firmware either Over-The-Air (OTA) or through iTunes. A detailed guide on how to do this can be found by clicking here.
Step 2) Next, download RedSn0w 0.9.13dev4 for the Mac OS X or Windows operating system using the download mirror below or through the iJailbreak Downloads Section.
Download RedSn0w 0.9.13dev4 (Mac OS X)
Download RedSn0w 0.9.13dev4 (Windows)
Step 3) Once you have downloaded RedSn0w 0.9.13dev4 you will need to launch it by double clicking on the redsn0w app (Mac OS X).
Windows: Once you have downloaded RedSn0w 0.9.13dev4 you will need to launch it by first extracting RedSn0w, then right clicking on the RedSn0w.exe and clicking the Run as administrator option (if applicable).
Step 4) With RedSn0w 0.9.13dev4 up and running you will need to click the Extras button. You will now see a few buttons presented to you. The button you are interested in is the Select IPSW button. Click this now and select your iOS device’s corresponding iOS 6 firmware. If you do not know where you saved your iOS 6 firmware file to then you can click here to download it again.
Step 5) Upon selecting the iOS firmware click the back button, followed by the Jailbreak button.
Step 6) After clicking the Jailbreak button RedSn0w 0.9.13dev4 will begin processing the iOS 6 firmware.
When the firmware has been processed you will come to a screen with a few options for your Jailbreak. Ensure that the “Install SSH” option is checked, click the Next button and you will come to a screen where you will need to put your iOS device into DFU mode.
Read through and follow the instructions presented to you which is to plug in and power off your iOS device and click the next button.
Step 7) When you click the next button you will need to follow the instructions presented to you to put your iOS device into DFU mode.
- Hold down Power (corner) button for 5 seconds.
- Without releasing the Power button, also hold down the Home (bottom center) button along with the Power button for 10 seconds.
- Without releasing the home button, stop holding down the power button for up to 15 seconds.
Step 8) After you successfully enter DFU mode RedSn0w 0.9.13dev4 will begin jailbreaking the iOS device. DO NOT interrupt or use the computer during this time. When the iOS device is finished being jailbroken it will reboot into a non-Jailbroken state. This is because you will need to boot it tethered.
Step 9) Launch RedSn0w again if you exited out of it, click the Extras Button > then click the Select IPSW button and select the iOS 6 firmware again. Next click the Just boot button and you will need to put the iOS device into DFU mode again. Once your iPhone or iPod Touch is in DFU mode it will boot into a Jailbroken state.
Install Cydia On iOS 6 [Mac OS X / Windows]
Step 1) You will now need to access your iPhone or iPod Touch over SSH. You can use the default Terminal utility, Cyberduck or any other SSH client to do this.
Windows: You can use the the popular WinSCP program to do this.
Step 2) Once you are connected to your iOS Device through an SSH client, enter the following command compliments of Kr1sis:
wget -q -O /tmp/cyinstall.sh http://downloads.kr1sis.net/cyinstall.sh && chmod 755 /tmp/cyinstall.sh && /tmp/cyinstall.sh
Step 3) You should now see Cydia appear on your SpringBoard (homescreen), followed by a re-spring.
Step 4) Tap on the Cydia icon, let is organize its filesystem and then you are done! You have just installed Cydia on the iOS 6 firmware generation. If for some reason Cydia didn’t launch you can try rebooting tethered with RedSn0w and repeating steps 1-3.
Your iPhone 4, iPhone 3GS or iPod Touch 4G should now be Jailbroken on the iOS 6 firmware with Cydia installed. Please remember that this is an unofficial method and the iPhone Dev-Team will release an updated version of RedSn0w shortly which will be more stable. As always, if you have any questions or further thoughts please drop us a line in the comments.
