• Thin plastic pry opening pick
• Nylon spudger
• Suction handle

Step by step

1. 1

   Step 1: Power Off and Eject the SIM Tray

   Shut down the smartphone completely to eliminate electrical hazards.

   Insert a SIM eject tool into the pinhole on the side of the chassis and remove the SIM card tray.

2. 2

   Step 2: Heat the Rear Cover

   Lay the phone face down on a clean, padded surface.

   Apply controlled heat around the outer perimeter of the back panel using a heat gun set to approximately 70°C (158°F) for two minutes to soften the factory adhesive.

3. 3

   Step 3: Slice the Rear Adhesive

   Attach a suction handle near the bottom edge of the rear panel and lift gently to create a microscopic seam.

   Insert a thin plastic pick into the gap and slice through the adhesive perimeter, taking care not to pry excessively, then lift the back cover free.

4. 4

   Step 4: Remove the Loudspeaker Bracket Screws

   Identify the lower plastic bracket that houses the loudspeaker and shields the charging daughterboard.

   Extract all visible Phillips #00 screws holding this lower assembly in place and keep them organized.

5. 5

   Step 5: Unclip and Remove the Loudspeaker Module

   Insert the tip of a nylon spudger beneath the loudspeaker bracket.

   Gently lever it upward to disengage the plastic retaining clips, then lift the assembly away to expose the charging daughterboard.

6. 6

   Step 6: Disconnect the Battery

   Locate the battery flex connector on the main logic board before handling any lower electrical components.

   Pry the connector straight upward with a plastic spudger to cut power across the entire device and prevent accidental short circuits.

7. 7

   Step 7: Detach the Interconnect Flex and Antenna

   Use a spudger to pop the wide main-to-sub interconnect ribbon cable connector off the lower daughterboard.

   Use precision tweezers to lift the circular coaxial RF antenna connector straight off its socket without bending the center gold pin.

8. 8

   Step 8: Pry Up the Damaged Charging Board

   Slide a flat spudger gently underneath the daughterboard to separate it from the thin layer of adhesive anchoring it to the frame.

   Carefully remove the board while ensuring the rubber microphone gasket remains intact in its frame pocket.

9. 9

   Step 9: Seat the New Charging Daughterboard

   Verify that the lower microphone seal is properly aligned in the housing.

   Lay the replacement Samsung Galaxy M08 daughterboard into the frame recess and ensure the USB Type-C port slides squarely into the exterior port cutout.

10. 10

    Step 10: Reconnect Ribbons and Antenna

    Snap the wide interconnect ribbon firmly back into place on the new board.

    Align the coaxial antenna plug directly over its mating socket and press down lightly until you feel a positive click.

11. 11

    Step 11: Reconnect Battery and Test

    Reattach the battery connector to the mainboard and connect a compatible Type-C charger.

    Confirm that the phone registers current, the charging graphic appears on screen, and the lower microphone functions correctly during a test recording.

12. 12

    Step 12: Reassemble and Seal the Device

    Reinstall the lower loudspeaker cover and tighten its Phillips screws securely without over-torquing.

    Clean residual glue from the frame, apply fresh adhesive along the perimeter, press the rear panel firmly back onto the chassis, and reinstall the SIM tray.
