Follow this guide to remove and replace the motherboard for the Galaxy S10+.

The hardest part of this guide is removing the back cover from the phone.

  1. Insert a SIM card eject tool, bit, or a straightened paperclip into the hole on the SIM tray, located at the top edge of the phone next to the plastic antenna band. If you inserted the tool into the other hole, don't worry—the microphone and the ingress gasket are mounted out of harm's way. Press firmly to eject the tray.

    • Press firmly to eject the tray.

    • Remove the SIM card tray.

    • When reinserting the SIM card, ensure that it is in the proper orientation relative to the tray.

  2. Unplug and power off your phone before you begin. Heat an iOpener and apply it to the back cover's right edge for two minutes. A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

    • As you wait, take a look at the image of the removed back cover and take note of where the adhesive is located.

  3. Rest the heated right edge of the phone on something that is about  0.5 inches (13 mm) thick. This angles the phone for the opening tool. Brace the left edge of the phone with your fingers so that the phone won't slide. Pull on the suction cup with firm pressure. Press the edge of an opening tool into the seam between the back cover and the frame.

    • Press the edge of an opening tool into the seam between the back cover and the frame.

    • Slide the opening tool back and forth along the seam a few times.

  4. Heat an iOpener and apply it to the same edge of the phone for two minutes. Apply a suction cup to the back of the phone, as close to the center of the right edge as possible (where the adhesive is narrowest). Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Pull on the suction cup with strong, steady force to create a gap between the back cover and the frame.

    • Insert the point of an opening pick into the gap.

    • Due to tight tolerances, this may take multiple attempts.

    • If you are having trouble creating a gap, your best bet is to apply more heat to the edge and try the previous step again.

    • You can try applying a few drops of high concentration (over 90%) isopropyl alcohol into the seam to help loosen the adhesive.

    • Do not apply excessive force with the pick, or you will risk cracking the back cover glass.

  5. Slide the opening pick along the edge of the phone, slicing through the adhesive. Do not attempt to slice the adhesive holding the corners down before applying heat. If you do, you may crack the back cover. Leave a pick in the seam to prevent the adhesive from re-sealing.

  6. Apply a heated iOpener to the bottom edge of the phone for two minutes. Insert an opening pick into the right edge near the bottom right corner. Carefully slide the pick around the corner. Continue cutting along the bottom edge and around the bottom left corner.
    • Apply a heated iOpener to the bottom edge of the phone for two minutes.

    • Insert an opening pick into the right edge near the bottom right corner.

    • Carefully slide the pick around the corner. Continue cutting along the bottom edge and around the bottom left corner.

    • If the cutting feels difficult, re-apply heat to the edge before continuing.

    • Leave an opening pick in the seam to prevent the adhesive from re-sealing.

  7. Continue heating and slicing around the remaining edges of the phone. When cutting around corners, be sure that the corner is thoroughly heated. When cutting around corners, be sure that the corner is thoroughly heated.
