Sometimes Android includes device drivers and sometime not. So we need to manually download USB drivers.

Just search into your Preferred Search Engine (I recommend Microsoft Bing) by typing Usb Drivers for [Device name]. Then open a website and download usb driver.

Most of New devices doesn't allowed to installed custom Recovery. So the problem happens. If you still this error then you can use below steps

Sometime Device fail to boot after flashing SuperSU.zip. It happens if your SuperSU.zip goes corrupt. You need to download a fresh copy of SuperSU.zip from here and need to copy the file again into your device root directory and install it again.

Sometime SuperSU installed like a User Application, It means you can easily uninstall SuperSU from your device from setting. For Preventing this, you need to install SuperSU as System App.

Install /system/app mover into your Device.
Click on the SuperSU from the list and restart your Device.
