Becoming the root user of the Google Nexus 5X smartphone is what developers need before they can begin making changes to the software. Since the Google Nexus range of devices was mostly inspired for developers, it only makes sense that many Google Nexus 5X smartphones owners are going to want to root the device. It is probably a good thing that many are developers too because the Google Nexus range of smartphones and tablets are always getting the newer versions of Android first so the rooting methods can also be tricky.
Once you manage to root the Google Nexus 5X smartphone you can start installing the apps that need root access before they can run. This guide not only installs Chainfire’s SuperSU but it enables it as well which means the root apps you download can be opened and run, and the SuperSU will bring up a message on the display asking whether or not you want to grant the app access to the root file system of the device.
There are thousands of useful root applications that people install. One of the root apps that might interest you is the Viper4Android  app. The Viper4Android app is developed to make your favorite music sound better than the standard headset connected to the Google Nexus 5X smartphone can usually deliver. Dubbed the best audio accessories manager app for Android, Viper4Android can improve the sound coming from the headphones so you can enjoy all the music you usually listen to in a way like you have never heard it before. The Viper4Android app is just one example of on additional app that a root user can install.
Here is everything that you need to root Google Nexus 5X smartphones when they are running on the Android 6.0.1 Marshmallow software updates with the MTC19V build number:
- You need to have the Google Nexus 5X smartphone to use the custom recovery image that is available for this guide. The guide works for the Android 6.0.1 Marshmallow updates with the MTC19V build number, but it might not work for future updates.
- You must have a computer that is running on a version of Windows operating systems to use this guide. Any other operating system will not be able to use our version of the ADB (Android Debug Bridge). Those who are unable to come up with a Widows PC can install ADB for Linux and Mac from other sources, but those operating systems also require separate ADB commands which are why we do not include them in our guides. You can, however, use the same TWRP version of SuperSU that is available in this tutorial and learns how to use the ADB for your different operating systems and still manage to get root access on the Google Nexus 5X smartphone when it is running on the Android 6.0.1 Marshmallow updated that come with the MTC19V firmware build number.
BEFORE WE BEGIN
- Note that if you do not have the Developer Options menu unlocked already you need to do it now by tapping on the Menu > Settings > About Device > Build Number seven times. Just keep tapping until it counts you down letting you know how many more taps are left for you to become a developer of the operating system.
- Enter the Developer Options menu on the Google Nexus 5X smartphone by tapping on the Menu > Settings > Developer Options and then check the box that is there available for the USB Debugging to turn that mode on. Once the USB Debugging is turned on, you may leave the Developer Options menu now, and Android is intelligent enough to remember your settings.
