Introduction

This guide takes you through the steps to remove a logic board in a Blackberry Torch 9800. Installing the new logic board is the same process, in reverse. This project will void your phone warranty.

  1. Remove the back cover and the battery.
    • Remove the back cover and the battery.

    • Unscrew the four screws using a T6 screwdriver.

    • Removing the top right screw (with the blue cover) will void the warranty.

  2. Remove the side trim using the plastic opening tool.
    • Remove the side trim using the plastic opening tool.

    • Apply pressure to push the top side of the side trim towards the phone while pulling the bottom away from the phone to remove the side trim.

    • The side trim is fragile and easily fractured, so handful it with care.

    • Remove the two screws that have been revealed at the top of the device using the T6 screwdriver.

    • You should now be able to easily lift the back panel from the phone.

    • Using your hands, carefully peel the three ribbon cable caps from the logic board.

    • Lift logic board slightly. The logic board will remain attached to the phone by a small antenna wire.

    • Using your hands, carefully lift the clasp attached to the antenna wire straight upward away from the logic board.

    • Make sure not to disconnect the antenna wire from its clasp.

    • The logic board should now be completely separate from the phone.

Conclusion

To reassemble your device, follow these instructions in reverse order.
