There is a new root method available for the Nvidia Shield tablet running on the current Android 6.0 Marshmallow software update. Attempting to root the Nvidia Shiled using the older method for Android Lollipop updates is no longer working.

The new method that is tested and working by XDA Developer senior members is making use of the SuperSU and a new boot image file.

  3. Open the folder where you have ADB and hold the Shift key and right-click within the folder where it shows a white background.

In conclusion, you should have your Shield tablet successfully rooted and ready to install the root-requiring applications from the Google Play Store like the Titanium Backup app. Titanium is the best way to back up any device running Android, apart from using the NANDroid Backup feature that comes with TWRP Recovery. Titanium also excels at removing the bloatware a device ships with out of the box. The Nvidia Shield isn’t famous for shipping with too much bloatware but you should be able to remove the stock apps just like any other device. Doing so can increase the performance of your Nvidia device.
