Step-by-step

  1. 1

    Power Off Device

    1 min

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

  2. 2

    Remove SIM Tray

    1 min

    Insert the SIM eject tool into the pinhole on the top edge of the phone. Push firmly to eject the tray, then remove it.

  3. 3

    Heat Back Glass

    3 min

    Use a heat gun or hairdryer on medium heat to warm the outer edges of the rear glass for 2 to 3 minutes. This softens the strong factory perimeter adhesive.

  4. 4

    Attach Suction Cup

    1 min

    Place a suction cup on the bottom third of the rear glass near the charging port. Press down firmly to create a tight vacuum seal.

  5. 5

    Create Opening Seam

    2 min

    Pull up firmly on the suction cup to lift the rear panel slightly away from the frame. Insert a plastic opening pick into the small seam.

  6. 6

    Slice Perimeter Adhesive

    5 min

    Slide the opening pick around all four edges of the back glass to slice through the adhesive. Do not insert the pick deeper than 4 mm to avoid damaging inner cables.

  7. 7

    Lift Off Back Glass

    2 min

    Gently lift the back glass panel up and separate it from the phone body. Store it carefully on a clean surface.

  16. 16

    Lift Motherboard Assembly

    3 min

    Carefully lift the motherboard out of the frame housing by grabbing the top corners. Place it safely on an anti-static mat.

    2 min

    Apply a drop of high-purity isopropyl alcohol around the haptic vibration motor. Pry it out using precision tweezers.

  18. 18

    Loosen Battery Adhesive

    3 min

    Apply high-purity isopropyl alcohol along the top and bottom outer edges of the battery. Allow 2 minutes for the solvent to dissolve the glue.

    Pry Out Battery

    4 min

    Place a suction cup on the battery and lever it upward using a broad plastic opening tool. Never insert metal tools near the battery pouch.

    Transfer the battery, vibration motor, sub-board, and motherboard into the new frame assembly. Reassemble the remaining components in reverse order.
