Apple recently released iOS 6 beta 3 for developers and redsn0w has already been updated to version 0.9.13 dev 3. If you happen to be a jailbreak developer, you can jailbreak Apple’s latest version of operating system so that you can test your jailbreak apps for compatibility.
Let’s see how to go about jailbreaking iOS 6 beta 3 using redsn0w, however, users should make a note that redsn0w version 0.9.13 dev 3 is a developer version and shall not be confused with general public release, and hence you may encounter certain bugs and unstability besides, this release will just jailbreak and not install Cydia, but users requiring Cydia can install it later. If you aren’t a developer and don’t know what you are doing, it is suggested that don’t proceed with the jailbreak.
1. Download redsn0w 0.9.13 dev 3 files from here.
2. Save the iOS 6 beta 3 firmware file (IPSW) from Apple’s developer portal and place it in some easily accessible folder.
3. Place your iPhone, iPad, or iPod touch on DFU mode. In order to put your device on DFU mode, scroll down to find the instructions.
4. Once the device is on DFU mode, launch redsn0w on your PC and click Extras
5. Press the button which reads Select IPSW, after which you have to navigate to the location where IPSW for iOS 6 beta 3 is saved.
6. Once you have selected the location of IPSW file of iOS 6 beta 3, click the button which reads “Jailbreak” on main screen of redsn0w.
7. You have to make sure that “Install SSH” option is checked before continuing.
Putting apple device on DFU (Device Firmware Update) mode is very different from placing it on Recovery Mode. While being a bit tricky, it requires a while to get there.
• Connect iPhone, iPod touch, or iPad into your Mac or Windows PC using the USB cable while making sure that iTunes is running on the computer.
• Now you are required to press the sleep button (can be found on top of the device) and home button (the only button on front) simultaneously.
• Both the buttons should be held down simultaneously for about 10 seconds. If you see an Apple logo on screen, it means you haven’t done it right and you need to give it another shot.
• Now you have to let go the sleep button and just keep pressing the Home button for another 5 seconds. At this stage, if you see “Plus into iTunes” screen, you have done it wrong and you have to try it again.
• In case the screen stays dark, you have successfully put your device on DFU mode. Cheers.
Since putting the device on DFU mode is a bit tricky, you should not be afraid to give try again and again until you get it right.
The jailbreak as of now is tethered and requires you to connect your jailbroken apple device running iOS 6 beta 3 to computer running redsn0w in order to boot your device. To perform a tethered boot, follow the steps below:
1. Place your iPhone, iPad, or iPod touch on DFU mode using the procedure mentioned above.
2. From the main screen of redsn0w, go to Extras and press the “Select IPSW” button in order to navigate to location where IPSW file of iOS 6 beta 3 is located.
3. Once the IPSW file is selected, go to the main screen under extras and press the button which reads Just Boot in order to make a tethered boot.
Your device will reboot after a while and then you should be good to go. Again, redsn0w version 0.9.13 dev 3 is just a beta version of redsn0w released for developers and is as prone to bugs as much as the iOS 6 itself in its current shape. You can expect crashes and is only recommended for developers.
