Slightly pry open one corner of the device by using your finger nail to separate the screen from the back case.

Use an opening tool to carefully detach the back case from the tablet. Start by inserting the tool where your fingernail opened a gap, and work around all four sides of the device.

There will be a slight click noise as you free each tab.

Once the case is completely free, carefully lift it and place it face up on the workstation, being cautious not to damage the speaker wires connecting the two halves.
