Locate the four 5mm Phillips head screws, one at each corner of the tablet.
Remove the screws using the Philips #00 screwdriver.
Next step is to pull apart the front and rear cover using the IFixit Plastic Opening Tool.
For that, locate the notches between the two cases.
Place the tool in the notches and start separating the two covers apart.
Repeat step two until 3/4th of the rear cover is unlatched.
Proceed to remove the rear cover by gently pulling it apart by hand.
Locate the two lower bumpers on the back cover. These two are the only rubber feet.
Flip the cover over to reveal the inside.
Locate the two rubber tabs, one for each foot, on the inside of the rear cover.
Push the two tabs on each foot in using the pointed end of a spudger.
It may take a little effort to push in the tabs. Try prying with the pointed end of the spudger and wiggling the tab free.
Flip the cover back over to reveal the outside of the cover and remove the rubber feet if they haven't fallen out already.
