Update Android One Devices

If you have an Android One Device and you want to get Android 4.4.4 KitKat on it, the easiest way to do so is to use CM 11 custom ROM. In this guide we’re going to show you how.

Prepare your phone:

As this is a custom ROM and not an official release from Google that we’re going to use, you’re going to need to install a custom recovery and root your device.
This guide and the ROM we are going to be using is only for Android One. Make sure you have the right device by going to Settings>About device.
Charge your battery so that it has at least over 60 percent of its battery life.
Backup your important contacts, call logs and SMS messages
Backup your important media content by copying them manually to a PC or laptop
Use Titanium Backup on your system data, apps and any other important contenet.
Use Backup Nanadroid.

Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
