How To: Jailbreak iOS 6.1 Beta 2 Build 10B5105c On iPhone 4, iPhone 3GS, iPod Touch 4G With RedSn0w 0.9.15b3 [Mac OS X]

Apple released the iOS 6 beta 2 build 10B5105c firmware today and although the changes are minute, if you are a developer seeking to Jailbreak iOS 6 beta 2, you will be glad to know it is indeed possible. The process is exactly the same as Jailbreaking the previous beta firmware, in that you point RedSn0w to iOS 6.0 rather than the actual firmware your device is running.

Keep in mind that this Jailbreak is still only for A4 devices and is tethered. DO NOT update to the iOS 6 beta 2 firmware if you are not a developer.

Supported Devices Include

• iPhone 4 CDMA
• iPhone 4 GSM
• iPhone 3GS (Untethered Jailbreak if old-bootrom)
• iPod Touch 4G

How To Jailbreak iOS 6.1 Beta 2 On Mac OS X

Step 1: The first thing you will need to do is download RedSn0w 0.9.15b3 for the Mac OS X operating system using the download mirror below or through the iJailbreak Downloads Section. You will also need to download the iOS 6 firmware for the device you are Jailbreaking, which can be found in the downloads section.

Download RedSn0w 0.9.15b3 (Mac OS X)

Step 2: Once you have downloaded RedSn0w 0.9.15b3 and your iOS 6 firmware file you will need to launch it by double clicking on the Redsn0w app. Keep in mind that to launch RedSn0w on OS X 10.8 Mountain Lion you will need to hold down the control button, click the RedSn0w and then click the Open option.

Step 3: With RedSn0w up and running you will need to simply click the Extras button.

Step 4: Next click the Select IPSW button and select the applicable iOS 6 firmware file for your device. After RedSn0w successfully recognizes the firmware you will need to click the Back button, followed by the Jailbreak button.

Step 5: Once you click the Jailbreak button you will be presented a screen with preparation instructions for entering DFU mode. Read through these instructions, power off your iPhone or iPod Touch if you haven’t already, and then click the Next button.

Once you click the Next button you will need to execute the steps shown on-screen, which are:

• 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 6: After you have entered DFU mode, RedSn0w 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 Cydia” option is checked, and then click the Next button to begin the actual Jailbreaking process.

Step 7: RedSn0w will now begin jailbreaking your iPhone or iPod Touch. 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 (or in some cases will not make it past the Apple logo). This is because you have a tethered Jailbreak and will need to boot it using RedSn0w.

Step 8: Launch RedSn0w again if you exited out of it, click the Extras button, click the Select IPSW button, browse for your device’s iOS 6 firmware again and then click the Just Boot button. You will now need to put the iPhone or iPod Touch into DFU mode again. Once your iOS device is in DFU mode it will boot into a Jailbroken state.

Note: Remember that you will need to repeat Step 8 every time your iPhone or iPod Touch loses power.

There is no reason why a non-developer would want to upgrade to the iOS 6.1 beta 2 firmware as iOS 6.1 adds very few new features, but if you are a developer congratulations on Jailbreaking iOS 6.1 beta 2 tethered. If you have any further questions or thoughts please turn your attention to the comments section below.
