Step-by-step

  1. 1

    Power Down the Galaxy Fold

    1 min

    Press and hold the power button, then select Power Off on the screen. Ensure the fold is completely powered down before starting.

  2. 2

    Heat the Rear Cover Glass

    3 min

    Apply a heat gun or hairdryer on medium heat along the rear outer glass edges for two minutes. This softens the factory adhesive backing.

  3. 3

    Attach Suction Cup

    2 min

    Place a suction cup on the lower portion of the rear glass panel. Pull upward gently to create a slight separation between the glass and the frame.

  4. 4

    Slice Rear Panel Adhesive

    4 min

    Insert a plastic opening pick into the gap near the bottom edge. Gently slide the pick along the perimeter to slice through the adhesive tape.

  5. 5

    Lift Off the Rear Glass

    3 min

    Carefully remove the detached rear glass panel and place it on a clean surface. Wipe away any loose adhesive residue from the chassis.

  6. 6

    Unscrew Motherboard Cover Plate

    3 min

    Remove the Phillips #000 screws securing the plastic motherboard upper cover and wireless charging coil frame. Lift the cover off the phone.

  7. 7

    Disconnect Both Battery Cables

    2 min

    Locate the primary and secondary battery connectors on the mainboard. Pry both connectors straight up using a plastic spudger to cut power.

  8. 8

    Disconnect Volume Flex Connector

    2 min

    Locate the small volume button ribbon connector along the upper side edge of the mainboard. Use a spudger to unsnap the press connector.

  9. 9

    Peel Up Volume Flex Cable

    3 min

    Slide a flat spudger or thin tweezers beneath the volume button flex ribbon attached to the side frame. Gently peel the glued cable away from the aluminum frame.

  10. 10

    Remove Volume Switch Bracket

    3 min

    Use fine tweezers to unclip the small metal retaining bracket securing the physical volume button switches. Gently ease the bracket and switch assembly out.

  11. 11

    Install Replacement Volume Cable

    4 min

    Insert the new volume switch bracket into the side frame slot. Align the flex ribbon guide holes with frame pins and press the adhesive backing firmly.

  12. 12

    Reconnect Cable and Batteries

    2 min

    Snap the new volume flex connector back onto the motherboard socket. Reattach both battery press connectors until they click into place.

  13. 13

    Reinstall Motherboard Shield

    3 min

    Position the upper motherboard cover plate over the mainboard. Replace and tighten all Phillips #000 screws to secure the shield.

  14. 14

    Reseal the Rear Glass

    4 min

    Apply new pre-cut adhesive tape around the perimeter of the phone frame. Align the rear glass panel and press firmly around all edges to seal.
