Samsung Galaxy S10 Motherboard Replacement

Insert a SIM card eject tool, SIM eject 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.

Press firmly to eject the tray.

Remove the SIM card tray.

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.

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

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.

With the opening tool in place in the seam, slide it back and forth along the seam to loosen the back cover.

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.

Insert the point of an opening pick into the gap.

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. The glass is heated enough when it is barely too hot to touch.

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

Slide the opening pick along the edge of the phone, slicing through the adhesive.

Leave a pick in the seam to prevent the adhesive from re-sealing.

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.

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

Continue heating and slicing around the remaining edges of the phone.

Once you have sliced around the phone, twist an opening pick in one of the edges to help separate the back cover from the frame.

Lift the back cover slowly. Use opening picks to slice any remaining adhesive.

Remove the back cover.

Remove the eight 4 mm Phillips screws securing the top midframe to the phone.

The midframe is still held in place by a few plastic clips around the edge.

Insert the point of a spudger into the notch on the right edge of the midframe, near the volume up button.

Pry up to loosen the midframe from the phone.

Lift the midframe from the top corners and remove it from the phone.

To reinstall the top midframe:

Align the midframe's top edge to the phone and lay the frame down on the phone.

Use fingers to apply pressure along the midframe perimeter to snap the midframe clips back into place. The edges should sit flush against the phone edge.

Insert the flat end of a spudger underneath the battery connector, which is attached to the motherboard below the rear-facing camera.

Pry upwards to disconnect the connector from its socket.

Gently push the battery's flex cable away from the motherboard socket to prevent accidental contact.

Remove the seven 4 mm Phillips screws securing the lower midframe.

Insert the point of a spudger underneath the top right corner of the lower midframe.

Pry up to release the midframe from the phone.

Grasp the loosened end of the midframe with your fingers and lift upwards slowly.

Wiggle the midframe slightly to help release the remaining edge clips.

Remove the lower midframe. The loudspeaker is built into the lower midframe.

Use the flat end of a spudger to pry up and disconnect the display connector from its motherboard socket, located near the bottom right corner of the phone.

Use the point of a spudger to pry up and disconnect the headphone jack's connector from its motherboard socket.

Remove the three 3.7 mm Phillips screws securing the motherboard to the phone.

Insert the point of a spudger underneath the right edge of the motherboard, near the volume down button.

Pry up gently to loosen the motherboard from its recess.

Insert the point of a spudger under bottom left corner of the motherboard.

Pry up gently to loosen the motherboard from its recess.

Using your fingers, grasp the motherboard by the top corners.

Swing the motherboard slightly out of its recess. Be careful not to snag any cables along the way.

Pull the motherboard towards the top edge of the phone while wiggling the board slightly. This will loosen the charging port from its socket.

Once the charging port is freed from its socket, remove the motherboard.

Align the motherboard's charging port with the bottom edge of the phone.

Gently push the motherboard against the bottom edge of the phone until the charging port is completely seated.

Lower the motherboard and press into place. Be careful not to trap any cables underneath the motherboard. The board should sit flush against the frame.
