The downloaded file will be in a format of .tgz and you need to extract it using WinRAR extractor. Extract the files to a single folder so the installation process will be easier. Also copy the ADB and Fastboot tools to the same folder.
Enabling USB debugging
The USB debugging mode enables the connection between the PC and your Android device, this is generally essential in loading and changing certain software’s. Enable USB debugging by following the below steps.
- Go to Settings on your Tablet or Smartphone.

- Now Enable USB debugging.
Download Required Windows drivers

- In the command prompt type “adb reboot-bootloader”.
- This command will restart your Android device in Fastboot.

- On your Nexus device type “fastbook oem unlock”.
- The device will ask for confirmation to continue to unlock the boot loader.
- Confirm it by using the volume keys and select the option by pressing the power button
This process will erase your Nexus device memory completely and prepare it for the new Android L installation.

- Open the command prompt by double clicking the “py_cmd” file.
- In command prompt type “flash-all” command in it.
- Click on Enter and the installation process will start automatically.
