Google has just released the factory images for its newest iteration of Android, the Android M (aka Marshmallow), for a spate of Nexus devices including Nexus 5, Nexus 6, Nexus 9 and Nexus Player.
The Android 6.0 aka Android M build MPA44G is now available for download and manual installation via Google's Developer page. Nexus users who have already installed the latest Android offering from Google may go ahead and root the same, using the step-by-step guide provided below.
Key Points to Remember
- Rooting Android M is no longer an easy task as Google has introduced some major changes to the kernel. Hence users are required to flash a custom kernel such as Despair Kernel in order to gain root access on Android 6.0 MPA44G stock firmware.
- Back up important data and settings before you proceed with the rooting
- Ensure that you have installed the correct USB drivers for your Nexus device
- Your Nexus device's bootloader must be unlocked and it should be running Android M MPA44G stock firmware
