These are the guidelines to follow if you want to root Android 6.0 Marshmallow on Google Nexus 9 WiFi, so what are you waiting for? All owners of the tablet should be thankful for such a chance (well, Chainfire is once again the man behind the scene that made everything possible) and here I am to guide you.
The root guide is made to work only with the latest Android 6.0 Marshmallow factory image that has just been released. The factory image comes with the build number KRA58K, so be sure of the fact that you made no confusion, just as you have to install a custom recovery like TWRP on your Google Nexus 9.
An unlocked bootloader is required too if you want to manage installing the custom recovery and don’t forget to also set up ADB and Fastboot on your computer. In order to do that, take the he full Android SDK from here.
Then, install the Google Nexus 9 USB drivers on your computer as well and check that you have the Developer Options unlocked and the USB Debugging Mode enabled. If you already know those two things, then you can skip the steps. If not, head to the Settings > Developer Options > USB Debugging and make sure that box is checked; if you cannot even see any Developer Options menu, then you have to enter into Settings > About Device and tap the build number until the screen lets you know that it’s unlocked.
The root and installation procedure described during the following guidelines has been tested successfully, but it does not mean that it’s 100% safe. On the contrary, I want you understand that this is an unofficial operation, so the warranty of your device is doomed, just as you have to accept that you should not do anything based on your own judgment. A simple mistake could brick you Android based tablet, so be careful!
If you don’t want to revoke that warranty or you are not sure about what you have to do, you should not follow the steps from this guide. But if this is not a problem, I will go through the process in the following tutorial.
