Flip the Apple TV over so that the bottom of the unit is facing up.

You need to remove the rubber base to get access to the screws.

Starting at one side of the device, use a hairdryer or a heat gun to soften the adhesive holding the rubber base in place.

The rubber base will be hot after heating, take extreme caution while proceeding to avoid personal injury.

While the adhesive is still warm, peel the bottom of the rubber base upwards to detach it from the metal plate.

The rubber base can tear if the adhesive hasn't been softened enough.

Repeat the procedure described above until the rubber base has been completely removed.
