– Article released.

Apple recently released iOS 8.1.3 to the public and, in the release notes, they thanked the Taig team for helping find several vulnerabilities that were patched in the iOS 8.1.3 release which means that as of right now, if your device is running iOS 8.1.3 it cannot be jailbroken.


Luckily however Apple are still signing the iOS 8.1.2 IPSW file which means you can downgrade the device back to iOS 8.1.2 and jailbreak it again to get the jailbreak back.

As of right now there are no Cydia tweaks that are compatible with iOS 8.1.2 that trick the phone in to thinking the version of iOS installed is the latest version so that it cannot be upgraded so if the device is upgraded you must downgrade first by following this guide to get your jailbreak back.
