Preparing the workstation

You have to install the drivers of the Android device before you connect it to the workstation. The device’s drivers can be found in the internet. When the drivers are installed you should reboot the computer.

You need to make sure that the drivers were installed correctly. On your computer, from the menu, navigate to Start| Control Panel | System | Device Manager. There you need to find the name of the connected device with the record ADB Interface. If you cannot find this record, it means that the device drivers were installed incorrectly.
