Here’s how the game of iOS cat-and-mouse jailbreak works. A team releases a working jailbreak for the most recent version of iOS to the public. Apple moves to eliminate the exploit that made the last jailbreak possible, releases a new version of iOS, and stops ‘signing’ previous jailbreakable versions of iOS, meaning they can no longer be installed on devices. Rinse and repeat.
The last version of iOS, iOS 8.1.1, closed the hole that made the Pangu jailbreak possible. But now a new jailbreak has been released, that will jailbreak iOS 8.1.1 on any device. Here’s how to install it.
The jailbreak is called TaiG. It’s in Chinese, and it only works on Windows (although running it in a Windows virtual machine also works fine), but it jailbreaks every version of iOS from iOS 8.0 to iOS 8.1.1, and it works like a charm.
To install the jailbreak, download the TaiG tool, extract its contents, and run the tool as an administrator. For the device you intend to jailbreak, turn off ‘Find My iPhone’ and disable your passcode under ‘Settings’, then enable AirPlane mode. Plug your device into your computer, and when TaiG recognizes your device, uncheck the second box (the one that doesn’t say Cydia) and hit the green button. When you see the smiley face, your jailbreak is done!
I tried it, and it worked quite well. Of course, with Apple still signing iOS 8.1, it seems a little odd that a perfectly good jailbreak technique would be squandered on iOS 8.1.1 when it could have been held back for iOS 8.2. But I suppose we shouldn’t look a gift horse in the mouth.
