You will want to root the BLU Vivo Air LTE device if you want to install the Titanium Backup application and remove the BLU stock apps. Moreover, you want to root the Vivo Air handset if you want to try Xposed or the Greenify application. Apps are without question one of the main reasons to root a device, but there are other reasons too.
The KingRoot application is a one click rooting method to open the system internals or your device and it is known as more of a soft root because it doesn’t require the bootloader on your device to be unlocked. You will need to unlock the bootloader if you want to install a custom recovery after you finish this guide. Combining a custom recovery with root access is where you get most of your benefits outside of the applications. For example, combining root and a custom recovery means you can start taking complete backups with the NANDroid Backup button and then install the NANDroid Manager app to restore partitions at a time. Others like to install a custom ROM or even a custom kernel on a device.
These are the guidelines to root the BLU Vivo Air LTE device running on the Android 5.1 Lollipop software update:

Update: rooting the BLU Vivo Air LTE device in this guide is not done by the KingRoot tool, but by a similar tool which does result in the KingUser being installed on your device. It’s essentially doing the same thing as you would expect from the KingRoot tool, but it’s created by independent Chinese developers.
In conclusion, that’s how to root the BLU Vivo Air LTE device using the one click rooting tool from your computer. You should be able to remove the Kinguser app the same way you would remove it from KingRoot. When you remove the KingUser your device will no longer be rooted.
