Step 5 - Removing The Parts
Back to top

  • Now you can remove the MAIN board (motherboard) and SUB board (lower board), in one step.

  • They should come off with all other parts like the fingerprint sensor and cameras.

  • The SUB board is secured with some glue so pull it up carefully.

  • Also, pay attention to the antenna and flex cables that connect MAIN and SUB board.

Step 6 - Transferring The Battery And The Speaker

  • Use isopropyl alchohol to dissolve the glue under the battery.

  • Carefully remove the battery and avoid using sharp tools so you don't puncture the battery.

  • Use your tweezers to pry the speaker out of the old LCD assembly.
