Introduction

What you need

Step 1

              Rear Case

Before you being the replacement process, make sure the tablet is completely powered off.
Gently insert the plastic opening tool between the metal rim and the back plastic casing at the bottom of the tablet and pry the back casing away from the device. Continue to separate the back panel of the device from the front assembly.
Right-handed users will probably be more comfortable prying in a clockwise movement, while left-handed users will feel more comfortable doing a counter clockwise movement.
When taking off the rear case there will be periodic clicking noises. Do not worry about those noises. They are just the rear case being disconnected.
Be careful not to use too much force as the plastic clips can easily be broken.
