VAKUPLASTIC Suction Cup
The back cover is glued to the chassis. Remove the back cover by putting on a suction cup and pulling on it. Also use a pick to push against the frame. Heat your device with hot air beforehand so the glue will be easier to detach.

As soon as a gap appears between the back cover and the chassis, you can insert the pick between the two parts.
The back cover is painted on the inside. Remove any adhesive residue carefully to avoid scratches or cracks.

Use more picks to disconnect all the corners one after the other.
