Today, I am glad to present you a new Jailbreak for iOS 9.3.4 on 32-Bit devices! We're speaking about Trident Jailbreak that is available as Open Source on Github.
This Jailbreak only works with iOS 9.3.4 because the Kernel exploits used in here were patched in iOS 9.3.5 (and are therefore not working in iOS 10.2 as well).
Trident requires Xcode in order to be compiled and it is actually an app that allows you to gain full read-write access to the device. You can play with the code and extend its compatibility as the project is available for download.
Pangu Team actually helped on the development of this tool.
In the video you get everything you need to know about this new Jailbreak.
