Step-by-step

1. 1

   Eject the SIM Card Tray

   1 min

   Insert a SIM eject tool or paperclip into the hole next to the SIM tray on the right edge. Remove the SIM tray completely from the device.

2. 2

   Heat the Rear Glass Adhesive

   3 min

   Use a heat gun or hair dryer on low heat setting to warm the edges of the back cover for two minutes. This softens the factory adhesive securing the rear glass.

3. 3

   Attach Suction Cup to Rear Glass

   2 min

   Place a suction cup near the bottom edge of the rear glass panel. Pull up gently on the suction cup ring to create a slight gap between the glass and the frame.

4. 4

   Slice Through Edge Adhesive

   4 min

   Insert a plastic opening pick into the gap created beneath the rear glass. Carefully slide the pick along all four perimeter edges to sever the adhesive bond.

5. 5

   Remove the Rear Glass

   2 min

   Gently lift the glass panel away from the chassis once all adhesive is fully cut. Set the rear cover aside in a clean location.

6. 6

   Unscrew the Midframe

   3 min

   Use a Phillips #000 screwdriver to remove all 13 screws securing the inner midframe assembly to the phone body.

7. 7

   Separate Midframe from Display Assembly

   3 min

   Push down firmly on the battery while pulling up on the outer midframe edges to unclip it. Lift the midframe off the display assembly.

8. 8

   Disconnect the Battery Cable

   1 min

   Use the flat end of a spudger to pop the battery connector straight up off the motherboard socket. Disconnecting power immediately prevents ongoing electrical corrosion.

9. 9

   Disconnect Front Panel Flex Cables

   3 min

   Unplug the display flex cable, touch key cable, earpiece speaker, and front camera connectors from the logic board using a spudger.

10. 10

    Remove the Logic Board

    2 min

    Gently lift the logic board out of the screen assembly housing starting from the bottom edge. Ensure no connected cables catch during removal.

11. 11

    Pry Off Metal EMI Shields

    3 min

    Use precision tweezers to gently snap off any removable metal EMI shields covering integrated circuits on the logic board.

12. 12

    Submerge Board in Isopropyl Alcohol

    10 min

    Place the bare logic board into a shallow container filled with 99% isopropyl alcohol for 5 to 10 minutes to displace liquid and dissolve corrosion.

13. 13

    Scrub Away Corrosion

    4 min

    Gently brush corrosion-affected areas around surface-mount components and connector pins using a soft anti-static brush soaked in isopropyl alcohol.

14. 14

    Blow Dry with Compressed Air

    3 min

    Use short bursts of compressed air to clear remaining alcohol and loosened debris out from under surface components. Allow the board to air-dry completely for 15 minutes.

15. 15

    Reinstall Logic Board into Frame

    4 min

    Lower the dry logic board back into the screen assembly housing and reconnect all flex cables to their matching motherboard sockets.

16. 16

    Reattach the Midframe

    3 min

    Snap the plastic midframe back onto the display chassis and re-thread all 13 Phillips #000 screws securely.

17. 17

    Reseal the Rear Glass

    4 min

    Apply fresh precut adhesive strips to the perimeter frame, align the rear glass panel, and press firmly around all edges to seal the phone.
