Before starting we must remove the tray with the cards from the tablet that we are about to repair.

With the help of a plastic tool we will unhook all the edges of the back cover.

We remove the adhesive that gets in the way to carry out the following steps, and with a flat tip tool we will disconnect the battery in order to work with greater safety.

We remove the Phillips screw (PH # 00) that holds the shield that covers the flex connector, and with a flat tool we will disconnect the flex with POGO connectors, and thus we can remove the back cover and work more comfortably.

To finish, we introduce a few drops of isopropyl alcohol around the edge of the battery to soften it, we tilt the tablet slightly so that the alcohol affects most of the adhesive, and with the help of a flat tool we will take it off.
