Step by step

1. 1

   Step 1: Heat and Remove the Back Glass Panels

   Apply gentle heat to the upper and lower back glass panels using a heat gun to soften the adhesive.

   Place a suction cup on the glass, pull up slightly, and insert a plastic pick into the gap to slice through the adhesive around the perimeter.

   Step 2: Disconnect the Batteries

   Safety must always come first when working inside a smartphone.

   Remove the protective metal shields covering the motherboard by unscrewing the Phillips screws, then use a plastic spudger to disconnect both battery flex cables.

3. 3

   Step 3: Remove the Lower Board and Flex Cables

   Carefully disconnect the interconnect flex cables that bridge the top and bottom halves of the phone.

   Unscrew and gently lift out the lower board containing the charging port and microphone.

4. 4

   Step 4: Extract the Motherboard

   Disconnect the camera cables and any remaining antenna wires attached to the main board.

   Remove the securing screws and carefully lift the motherboard out of the upper housing using your fingers or a plastic spudger.

5. 5

   Step 5: Transfer the Batteries

   Apply a few drops of isopropyl alcohol around the edges of both batteries to dissolve the strong factory adhesive.

   Wait a couple of minutes, then gently pry them out with a flat plastic tool to avoid puncturing the lithium cells.

6. 6

   Step 6: Move Small Components to the New Frame

   Transfer the vibration motor, earpiece speaker, and any rubber gaskets from the old frame into your new OEM service pack frame.

   Ensure every tiny component sits perfectly flush in its designated cutout to prevent reassembly issues.

7. 7

   Step 7: Install the Motherboard and Lower Board

   Place the main motherboard and the lower board into the new display housing.

   Secure them with their respective Phillips screws and reconnect the camera modules.

8. 8

   Step 8: Seat the Batteries and Connect Cables

   Apply fresh adhesive strips to the battery compartments and press both batteries firmly into place.

   Reconnect all the interconnect flex cables, antenna wires, and finally the two battery connectors.

9. 9

   Step 9: Test the New Display

   Before sealing the phone, temporarily hold the power button to turn on the device.

   Verify that the inner foldable screen displays correctly, the touch functionality works, and the hinge opens smoothly.

10. 10

    Step 10: Seal the Back Panels

    Once testing is successful, turn off the device and reinstall the metal protective shields.

    Apply fresh adhesive to the upper and lower back glass panels, press them firmly into place, and clamp the phone gently for an hour to ensure a watertight seal.
