These are the guidelines to root Google Nexus 5 on Android 6.0.1 Marshmallow with the firmware build number MMB29K. Once you have the smartphones rooted using the guide below, you can start installing your favorite apps like the Full!Screen app. With Full!Screen, you can use more of the screen real estate on the Google Nexus 5 smartphone by removing the notification bar and the soft keys at the bottom of the device. The result leaves you with a larger screen — something many of us dream of having without having to up the size of our smartphone shells.
- The following guide is made to root Google Nexus 5 devices only. Do not try rooting and installing a custom recovery with these files on a different Nexus device running Android 6.0.1 marshmallow or you will likely brick that device.
BEFORE WE BEGIN
- We recommend every Google Nexus 5 owner backs up the device before starting the guide. You do not automatically lose the data on your device. However, if you want to apply a hard reset of any kind later one because you have soft-bricked your device, you will need to have backed up the data to restore that data. The kind of data we are referring to includes your phone contacts, pictures, music, videos, call logs, SMS text and any other data you can think of that is important to you.
