Fix setreuid Flaw With TaiG 2.2.1 On An Already Jailbroken Device, Here’s How

If you are already jailbroken on iOS 8.4, chances are that you jailbroke it using TaiG 2.2.0 which has a ‘setreuid’ security flaw that can give apps root access on your device. The good news here is that a fix for it is already out in the form of TaiG 2.2.1.

Now if you have just jailbroken using TaiG 2.2.1 or are going to jailbreak fresh using TaiG 2.2.1, you are obviously not affected by this. As mentioned above, this only affects those devices which were jailbroken using earlier versions of TaiG like version 2.2.0.

So what if you are jailbroken already on iOS 8.4? Do you have to restore to 8.4 again, jailbreak and set up everything again from scratch? Nope. There’s an update out on Cydia which includes fix for setreuid patch to prevent giving apps root access on your jailbroken iPhone or iPad.

Here’s what you need to do to update your already jailbroken iOS 8.4 device to TaiG v2.2.1 untether package from Cydia.

Note: If you have CyDown and Cydia Enable installed, update to their latest respective versions before installing this 2.2.1 update for TaiG. Not doing so will result in Cydia crashing after TaiG 2.2.1 update.

Step 1: Launch Cydia and wait for everything to load completely.

Step 2: Tap on Sources -> Edit -> Add and then add the following repositories:

apt.3kzhushou.com
apt.taig.com

Note: This update isn’t available on Cydia’s default Telesphoreo repository yet. But once it’s available, you won’t need to add TaiG’s repositories mentioned above.

Step 3: Now search for TaiG 8.1.3-8.x Untether v2.2.1 package and update to it.

Once the update is installed, the existing iOS 8.4 jailbreak on your iPhone, iPad or iPod touch will get the 2.2.1 upgrade which includes the all important fix for setreuid patch.
