Now first extract the .tgz archive and then extract the .tar file in the same folder where you have installed Minimal ADB and Fastboot tool (for Windows users the path will be: c:\Program Files (x86)\Minimal ADB and Fastboot).
    2. Next, download USB driver for Nexus devices, extract it and save it on your computer.
    3. Now, connect your device with the computer by using original USB cable and then follow this path in your computer: Control Panel -> Devices & Printers. You will see your device listed there as “MTP.” Now open its properties by clicking on your device name. In the next window, go to Hardware Tab and select your device (Nexus 5 or Nexus 7) and then choose “Properties”. In the next window, go to “Driver” tab and click on “Update Driver” and then choose the folder where you have saved the USB Driver files. The update progress will go on for few seconds, and once it is done, you will see your device as Android Composite ADB interface. Also, you will see a warning message in your device asking for permission to enable “USB Debugging.” Select “Always Allow” and enable it.
    4. Next, you have to switch-off your phone and boot it in Fastboot mode. To enable this mode, press and hold the volume down, volume up and power buttons at the same time. Alternatively, you can type “adb reboot-bootloader” in the command prompt to restart your device in fastboot mode.
