This guide will show the process behind replacing a daughterboard in the Samsung Galaxy Tab S3. This will be useful for fixing a broken charging port, as the port is soldered onto the daughterboard. It would also be useful if the home button, auxiliary, charging port and left speaker simultaneously stopped working, as these components all filter communications through the daughterboard to the motherboard for processing.

    • 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.

    • Be careful not to burn yourself while handling the hot iOpener. For more information on the iOpener, use the iOpener Instructions Guide.

    • 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.

    • Be careful to not break the glass when prying from the frame.

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

    • You can also use multiple opening picks instead of a plastic card.

    • As you remove the glass panel, be careful not to tear the ribbon connecting the motherboard to the display.

    • 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.

Do you need to remove the front display assembly to replace the daughterboard? From the images it appears you just have to go in through the back glass to do this job. Confused.
