How to jailbreak iOS 8.4 untethered with TaiG 2.2.1 on Windows

Avid iOS jailbreakers are in for some great news, as the TaiG jailbreak developer team has just released the setreuid security patch and stability improvements with TaiG jailbreak 2.2.1 tool for Windows, following a broken release of the same on Cydia and TaiG's official website sometime earlier.

It has been reported that Jay Freeman aka Saurik (the founder of Cydia) had earlier found the update unsafe for use, as the patch was not fully functional and hence he had pulled the update from Cydia.

It has been confirmed that the re-released TaiG 2.2.1 patch prevents apps from obtaining root privileges through setreuid and hence makes the jailbreak more secure as well as stable.

Here is the official changelog for TaiG 2.2.1 tool:

• Fixes setreuid patch to prevent applications from obtaining to root privileges through setreuid.
• Increases stability.

The only downside is that the 2.2.1 jailbreak update is Windows-only, like all other earlier jailbreak releases from TaiG. However, Mac OS X users can use the Windows Virtual Machine to jailbreak iOS 8.4 on a Mac.

Alternatively, you can update to the TaiG Untether package on Cydia. Just search for the TaiG 2.2.1 untether update and install it.

TaiG has also announced via Twitter that very few TaiG 2.2.1 users are currently experiencing Cydia crashes as Cydown changes Cydia's file permissions. However, a Cydown update or a fix should soon be available on Cydia.

Meanwhile, TaiG has also released an updated version of its untethered jailbreak tool (TaiG v2.3.0) on its official website. Those who are facing issues with TaiG 2.2.1 update can download the latest version and then follow the same steps to jailbreak their device on iOS 8.4.

Nevertheless, interested users who are yet to jailbreak their device on iOS 8.4 and those facing issues with earlier jailbreak can go ahead and install the TaiG jailbreak 2.2.1 on their iOS device, using the step-by-step guide posted below.
