Go to developers.google.com/android/nexus/images and download the appropriate image for your device, pick the android version you want.
-You'll get a tgz file, extract that
--There's a file in that extracted tgz, a zip file, when you extract it it's gonna show you all the .img files we're interested in.
-Extract that file.
--Now you'll see all the .img files... that's what we're intrested in.

Now that every command has finished, you flashed your factory image. so reboot.
when it boots, finish the setup and reboot once again and let it settle for about 5 minutes to let android relax after some hard work.
