Samsung Galaxy Tab S3 Daughterboard Replacement

To soften the adhesive holding the tablet together, heat up the edges of the glass panel using a heated iOpener on the edge of the device.

We used two iOpeners to open up the tablet. The process is doable with a single iOpener, but would take substantially longer. Alternatively, you can use a heat gun to quickly loosen the adhesive.

Leave the iOpener on edge for two minutes.

Place a suction cup near edge that you heated up with the iOpener.

Press down on the suction cup to create a seal, and pull up with force to create a separation between the display and the midframe.

Use an opening tool to split apart the glass panel from the midframe.

As you continue along the edge using the opening tool, use a plastic card to keep the glass separate from the midframe.

Pull off the glass panel using the suction cup.

Carefully disconnect the ribbon connecting the display assembly to the motherboard. You can disconnect this ribbon from either end.

Repeat steps 3 through 7 to remove the rear glass panel on the opposite side of the device.

Use a Phillips #000 screwdriver to unscrew the five screws securing the battery, and the twenty-two screws surrounding the midframe.

The midframe should snap off from the device’s motherboard.

Locate the ribbon running from the midframe and disconnect it from the motherboard with the flat end of a spudger.

Use the flat end of the spudger to pop off the connector between the battery and the motherboard.

Flip the midframe over and pop the battery out, making sure to slide it out from underneath the ribbon cables.

The battery should now be removed and detached from the device.

Use a spudger to pry up four press fit connectors from the lower board containing the charging port.

Pry up the two coaxial cables joining the daughterboard to the motherboard.

Pry the daughterboard up from the midframe with a spudger.

Remove the daughterboard.
