Step-by-step

  1. 1

    Eject the SIM Tray

    1 min

    Insert a SIM eject tool into the hole on the left edge of the phone. Push gently until the tray pops out and remove it completely.

  2. 2

    Heat the Rear Cover

    2 min

    Use a heat gun or hair dryer to warm the back cover edges for 2 minutes. This softens the adhesive holding the plastic rear shell.

  3. 3

    Attach Suction Cup

    2 min

    Press a suction cup near the bottom edge of the back panel. Pull upward gently to create a seam between the cover and midframe.

  4. 4

    Slice Rear Adhesive

    4 min

    Insert a plastic opening pick into the gap created by the suction cup. Slide it along all four sides to slice through the adhesive seal.

  5. 5

    Pry Open Rear Cover

    2 min

    Carefully swing the rear cover open like a book from the left side. Do not pull it away completely yet, as the fingerprint cable is still connected.

  6. 6

    Remove Motherboard Screws

    3 min

    Use a Phillips #000 screwdriver to remove all screws securing the plastic top motherboard cover. Keep track of the screws for reassembly.

  7. 7

    Detach Motherboard Frame

    2 min

    Insert a spudger under the top plastic frame and lift it up to detach it from the phone chassis. Set the frame aside.

  8. 8

    Disconnect Fingerprint Sensor

    2 min

    Use a flat plastic spudger to pry the fingerprint reader flex connector straight up from its motherboard socket. Remove the rear panel.

  9. 9

    Disconnect Battery Cable

    1 min

    Pry the battery connector directly up from the motherboard to safely cut electrical power to the device.

  10. 10

    Disconnect Interconnect Cable

    1 min

    Use the plastic spudger to detach the main display interconnect cable that runs across the top of the battery.

  11. 11

    Soften Battery Glue

    2 min

    Apply a few drops of high-concentration isopropyl alcohol along the top and bottom edges of the battery. Allow it to sit for 1 minute to weaken the adhesive.

  12. 12

    Pry Out Old Battery

    4 min

    Slide a wide plastic card or spudger under the battery from the side. Gently lever it upward until the adhesive releases and remove the battery.

  13. 13

    Clean Battery Recess

    2 min

    Clean any remaining adhesive residue from the frame recess using isopropyl alcohol and a lint-free cloth. Ensure the surface is completely dry.

  14. 14

    Apply Battery Adhesive

    2 min

    Place new custom battery adhesive strips onto the back of the replacement battery. Peel off the protective film backing.

  15. 15

    Place New Battery

    2 min

    Lower the new battery into the housing recess and press down firmly across its surface to set the adhesive.

  16. 16

    Reconnect Cables

    2 min

    Reattach the main display interconnect cable and the battery press connector to their motherboard sockets. Press gently until they snap into place.

  17. 17

    Reinstall Motherboard Shield

    3 min

    Align the plastic motherboard cover over the upper board and replace all Phillips screws firmly.

  18. 18

    Reconnect Fingerprint Flex

    2 min

    Position the rear cover close to the frame and snap the fingerprint sensor connector back onto its port.

  19. 19

    Reseal Rear Cover

    2 min

    Press the rear cover firmly around all edges to re-engage the adhesive and snap clips into place.

  20. 20

    Reinsert SIM Tray

    1 min

    Push the SIM card tray back into its slot on the side of the phone until it sits flush.
