Make sure you have installed drivers of your smartphone

Install ADB drivers for your phone.. or search for universal adb drivers.. install it.. reboot pc..

connect phone to pc using a good datacable.. go to settings>about.. tap build number till it says you are a developer.. then go to settings>developer options> turn on usb debugging.. now try on pc again..

it will show a prompt on phone to accept usb adb connection.. click allow..

adb would be working now.

just check it.........1.usb debugging must be on
2.usb tethering must be on
and now use command.....hope it will help u

I think you haven't checked usb debugging

you need to give the path of the adb files, right click the file location and click on open command from here
