1. The first thing for you to do is to switch off the device.
2. Press and hold the Power & Volume buttons for five seconds or so, until an Android logo appears.
3. Wait for the Lenovo logo to pop up. When it does, let go of the Power button. Do the same to the Volume Up button after the MMI menu appears.
4. Using Volume Up to scroll down and Volume Down to choose the option, select Recovery Mode.
5. Well done, you have reached Recovery mode.
