TaiG team has yet to release an update to their iOS 8.3 jailbreak tool, that would bring the updated version of Cydia Substrate. Interestingly though legitimate TaiG 2.1.0 has been leaked on the internet that features the new Cydia Substrate and is available for download. The new version of the tool was discovered by Reddit user seiterseiter1 who posted the download links on a Reddit thread. The leaked tool was found on TaiG’s own website and is in Chinese. A large number of users have tried jailbreaking their devices using this new version and have reported positive results.

Cydia Substrate is an essential Cydia component that is required by most jailbreak tweaks. When the TaiG 2.0 tool was released it became clear that an updated Cydia Substrate is not bundled with it, which prevented many tweaks to work on the new jailbreak. Since then everyone has been waiting for TaiG team to push an update to their tool with this all important component.

If you want to install the Cydia Substrate on your device then you can download the leaked version of TaiG from here and use it to jailbreak your device. If you are already jailbroken then it is a good idea to restore first.

Alternatively, you can download the .Deb file on an already jailbroken devices to get updated Cydia Substrate on it. Follow the steps below to do so.
