Solution: On LG Nexus 5, one must ensure that both the USB debugging mode and the USB Selection mode is set to CHARGING.

Ensure to delete adbkey and adbkey.pub from your ~/.android folder. (This folder is usually in C:\Users\username\.android)

Perform adb kill-server then adb start-server then adb devices on Command Line terminal. See: ADB Command

USB Selection Mode: When you plug the phone in, swipe down on screen and you will note Charging mode, listed as the last notification item. Ensure it says Charging - if anything else, simply tap and choose Charging as the mode. See: MTP Mode

IMPORTANT: You must install all drivers in all device mode. The USB cable must be connected to the phone and computer at all time.

1) If the device is ON and on the standard operation state, ensure both Nexus 5 and MTP listed devices in Device Manager is installed. The MTP should be loaded as Android Bootstrap Loader driver/device.

2) If the device is OFF, ensure the device is detected and the driver is installed.

3) If the device is in debug mode (when phone is OFF, hold Volume Up and Down button simultaneously and press the power button until you see the screen showing START), ensure that the driver is installed in that mode as well.

In each mode, the device is detected and Device manager will refresh to show the device detected.

Congratulations: Your device should show up as device when you run adb devicescommand.
