Before you start, make sure the tablet is off.

Remove the micro SD card.

Remove the 2 Phillips screws that secure the back cover.

To disassemble the back cover, we use this opening tool type "cortapizzas". With the plastic head we make sure not to scratch the casing.

Peel off the speakers to separate the back cover.

Remove the adhesive covering the side of the base plate, where the battery cables are soldered.

Peel off the battery, inserting a flat plastic spatula underneath and pushing to release the adhesive.

Finally, de-solder the battery cables. To do this, apply heat to the tin with the tip of the soldering iron while simultaneously pulling the cable gently.
