Thanks to a new One-Click tool, OnePlus One device owners can now backup the EFS folder before unchaining the system internals with root access. Commonly known to help Samsung devices, the EFS folder is also available in the OnePlus handset. The only difference is you cannot back them up in the same manner because there are subtle differences between branding which require unique tools. If you would like to learn how to backup the OnePlus One EFS folder in just one-click, please follow the guide below:

BEFORE WE BEGIN 

• Install the ADB Drivers on your computer.
