Step-by-step

  1. 1

    Power Off Tablet

    1 min

    Press and hold the Power and Volume Down buttons, then select Power Off on the screen. Ensure the device is completely shut down before starting.

  2. 2

    Heat Screen Edges

    3 min

    Apply heat evenly around the perimeter of the front screen using a heat gun set to low for approximately two minutes. This softens the strong adhesive holding the display to the frame.

  3. 3

    Attach Suction Cup

    1 min

    Place a suction cup near the middle of the left display edge. Press down firmly to create a secure vacuum seal against the glass.

  4. 4

    Insert Guitar Pick

    2 min

    Pull up gently on the suction cup to create a small gap between the glass and the bezel. Insert a opening pick into the gap.

  5. 5

    Slice Screen Adhesive

    5 min

    Slide the guitar pick carefully around all four edges of the tablet to sever the perimeter adhesive tape. Take care not to insert the pick more than 3mm near the top to avoid damaging the camera.

  6. 6

    Hinge Display Open

    2 min

    Gently lift the display assembly from the left edge like opening a book. Do not pull the screen away fully, as fragile ribbon cables are still connected.

  7. 7

    Remove Display Connector Shield

    2 min

    Unscrew the single Phillips screw securing the metal shield over the display cable connector. Lift and set the metal shield aside.

  8. 8

    Disconnect Display Cable

    2 min

    Use the pointed end of a plastic spudger to pry the display flex cable straight up from its socket on the logic board. Separate the screen from the body.

  9. 9

    Disconnect Battery Cable

    1 min

    Pry the battery connector directly upward from the logic board to disable power to the board completely. This prevents accidental shorts during the repair.

  10. 10

    Disconnect Camera Cables

    2 min

    Unplug the front-facing and rear-facing camera press-fit connectors from the main logic board using a spudger.

  11. 11

    Disconnect Interconnect Cables

    2 min

    Disconnect the main ribbon cables connecting the logic board to the lower sub-board using the flat edge of a spudger.

  12. 12

    Unclip Antenna Coaxial Cables

    2 min

    Use fine tweezers to carefully pry the antenna cable connectors straight up off their metallic sockets on the board.

  13. 13

    Unscrew Logic Board Screws

    4 min

    Remove all Phillips #00 screws holding the main logic board to the tablet's aluminum chassis frame.

  14. 14

    Remove Defective Logic Board

    2 min

    Gently lift the old logic board out of the housing from the top corner, ensuring no lingering cables catch on the board edges.

  15. 15

    Seat Replacement Board

    2 min

    Position the new logic board into the aluminum housing and align its mounting screw holes with the standoffs.

  16. 16

    Secure Logic Board Screws

    3 min

    Install and tighten the Phillips #00 screws to firmly anchor the replacement board to the chassis.

  17. 17

    Reconnect Ribbons and Antennas

    4 min

    Snap the camera cables, interconnect ribbons, and antenna coaxial connectors securely back onto their respective board headers.

  18. 18

    Reconnect Display and Battery

    5 min

    Reconnect the display press-fit cable, reinstall its metal bracket, connect the battery cable, and seal the screen assembly back onto the frame.
