How to jailbreak iOS 8.1.2 with TaiG 1.2.0 in Windows

Download the TaiG 1.2.0 from this link here.
– remember the file is not for Mac OS X. The developers of the tool do not cater for Max or Linux yet.

Download the file to the desktop of the computer and extract the contents.

Right click the mouse on the executable file and select the run as administrator option.

There’s two main boxes on the first screen on the tool: Cydia and 3k Assistant.

Uncheck the 3K assistant box.

Click the big start button and wait for the device to jailbreak.

Do not touch anything until it completes.

After it finishes you’ll find the Cydia icon in the app drawer.

Tap the Cydia icon and open Cydia to start installing Winterboard, tweaks and themes.
