Root Nexus 9

Chainfire, the rockstar of Android root community has just released a guide to root Nexus 9 devices. This rooting method is similar to the rooting method released to root Nexus 5 devices.

Ever since the Android 5.0 Lollipop update, the SELinux permission has been set to enforcing. This is done to enhance the security of the system. Although, this added step really does increases the overall security of the Android system, it makes it very difficult to root the Android devices.

Previously, just flashing the with a custom recovery was enough to get root permissions on your device. With Android 5.0 Lollipop, we had to find a way to set the SELinux permission to permissive but only to such an extent which doesn’t reduce the security of the entire system.

So, chainfire build a custom Kernel for us which sets the SELinux permission to permissive only to an extent such that we have root permission. But for the most parts, the permissions still remain enforcing which ensures maximum security while having the pleasures of possessing a rooted Nexus 9 device.

Following this tutorial might void your warranty. We are not responsible for what happens to your device. This guide is written to root Google Nexus 9 device only, don’t try it on any other device.
