The files that you unzipping need to be unzipped to the folder where your adb files are located. That is the one included in you environment path. Mine is platform tools so when I fire up adb I change directory to platform tools and then go from there.
Then you can start pushing the files to your device
Make sure adb recognizes your device first before pushing files. Type this command to see if you are set up correctly
This will show you device connected
