Note: This tool is Windows only for now, so you’ll either need a Windows computer, or a Mac with a virtual machine running Windows. I used a virtual machine for this tutorial (VMWare Fusion, and it was super easy.
You’ll also most likely need to downgrade to iTunes 12.1 so that you won’t get stuck at the 20% progress level during the jailbreak. I’ve outlined the full fix in this post. Downgrading iTunes shouldn’t take long at all.
Step 1: Download and extract TaiG 2.0 from our downloads page
Step 2: Disable Find My iPhone and Passcode lock on your device
Step 3: Connect your device to your computer
Step 4: Run the TaiG 2.0 tool and it should detect your device
Step 5: Uncheck the 3K assistant, but keep Cydia checked
Step 6: Click Start
Step 7: Wait until the jailbreak completes. If you see storage full errors, just ignore those
Step 8: Once the jailbreak completes, find the Cydia app on your Home screen and launch it
That’s all there is to it. This jailbreak works with iOS 8.1.3 through iOS 8.3.
