iOS 6.1.1 Untethered Jailbreak: How to Jailbreak iPhone 4/3GS/iPod Touch 4 Using Redsn0w 0.9.15b3 and Evasi0n
Apple recently released the iOS 6.1.1 beta version to developers, leaving the jailbreak community worried that the company might have patched existing exploits and inherent bugs for the next jailbreak. The good news for jailbreakers is that David Wang, aka planetbeing, has said that they still have few more exploits up their sleeves for future jailbreaks.
Here is what he had to say in a recent statement to Forbes: "Even if we could only find another one or two more [bugs], we'd still have at least one more jailbreak left in us. It's getting harder. But there are still a lot of vulnerabilities left."
As iPhone Hacks notes, despite Apple's increasingly heightened security in iOS, Wang reveals that combining a number of apparently harmless bugs could lead to a future jailbreak:
"It was just a question of being able to cleverly chain all these [bugs] together. These small bugs demonstrably can lead to compromise of the entire operating system."
Because Apple might just patch the exploits in next beta version or before the iOS 6.1.1 public release, it is recommended that iOS 6.1 jailbreakers should stay on the existing public release of evasi0n jailbreak. However, iOS users and developers who wish to explore the new beta version can follow our step-by-step guide below to jailbreak iOS 6.1.1 untethered on any A4 device including iPhone 4, iPhone 3GS and iPod Touch 4.
As Redmond Pie reports, the jailbreak method involves using Redsn0w to perform a tethered jailbreak, and then modifying iOS version number in SystemVersion.plist to trick Cydia's iOS 6+ untether files to provide an unrestricted break on iOS 6.1.1.
- Redsn0w 0.9.15b3 [Windows / Mac]
- An iPhone 4, 3GS or iPod touch 4 running iOS 6.1.1 beta 1(download from iOS Dev Center)
- iFile, the jailbreak file exploring tool which can be downloaded via Cydia.
- The original iOS 6.0 IPSW for your device. Download iOS 6 from here.
How to Jailbreak iOS 6.1.1 Tethered
Step 1: Connect the A4 device (iPhone 4, iPhone 3GS and iPod Touch 4) to the computer via original USB cable.
Step 2: Launch Redsn0w and point to the iOS 6.0 IPSW by going to Extras and then choosing Select IPSW. Then hit Jailbreak button in the main window.
Step 3: After the jailbreak initialisation process is complete, choose the iOS 6.0 IPSW file once more, and hit Just Boot. The device is now jailbroken tethered and running on iOS 6.1.1 beta 1.
How-to jailbreak iOS 6.1.1 untethered:
Step 4: First of all, install OpenSSH and iFile from Cydia, and browse to System/Library/CoreServices.
Step 5: Navigate to the bottom, tap on SystemVersion.plist, and open it with text viewer.
Step 6: In the .plist, search for information at the bottom of the page in between the tags, which should read "6.1.1". Now, just tap the Edit button in the top left-hand corner, and change that string to "6.1". Then, click Save button at the top right-hand corner.
Step 7: Navigate to Cydia, find evasi0n 6.0-6.1 Untether, and install it. Do a reboot and the iPhone will now be untethered on iOS 6.1.1 beta 1. Alternatively, Untether can be installed manually using Evasi0n's .deb file in iFile.
Finally, repeat steps 4 through 6 and modify the version number back to 6.1.1 from 6.1. Now the device has been successfully jailbroken
