Step-by-step

1. 1

   Eject the SIM card tray

   1 min

   Insert a SIM eject pin into the hole on the left side of the Moto G100. Press firmly to pop out the SIM tray and remove it completely.

2. 2

   Heat the rear panel

   3 min

   Use a heat gun on low power to warm the edges of the back cover for 2 to 3 minutes. This softens the adhesive securing the rear panel to the chassis.

3. 3

   Attach a suction cup

   2 min

   Place a suction cup onto the lower portion of the back cover. Pull upward firmly to create a small gap between the glass panel and the frame.

4. 4

   Slice through perimeter adhesive

   5 min

   Insert a plastic opening pick into the gap created by the suction cup. Carefully slide the pick around all four edges to slice through the rear adhesive.

5. 5

   Lift and remove the rear cover

   2 min

   Gently lift the back cover off the phone frame. Set the back panel aside in a safe, dust-free area.

6. 6

   Unscrew motherboard cover screws

   4 min

   Use a Phillips #00 screwdriver to remove the screws securing the upper motherboard shield. Keep track of each screw for reassembly.

7. 7

   Remove the upper plastic shield

   2 min

   Insert a flat spudger under the motherboard shield and pry upward to release its plastic retaining clips. Lift and remove the shield.

8. 8

   Disconnect the battery cable

   1 min

   Pry up the press-fit battery connector from the top-left corner of the motherboard using a plastic spudger. This cuts power to the board.

9. 9

   Disconnect display flex cable

   1 min

   Use the edge of a plastic spudger to gently pop up the display flex connector from the motherboard.

10. 10

    Disconnect main interconnect cable

    1 min

    Locate the main ribbon cable linking the motherboard to the lower sub-board. Carefully unseat its press-fit connector.

11. 11

    Disconnect side button flex cable

    2 min

    Use fine tweezers or a spudger to lift the lock tab on the ZIF connector and slide out the side power/volume key ribbon cable.

12. 12

    Unclip antenna coaxial cables

    2 min

    Gently pry up the head of each antenna coaxial cable connected to the right edge of the logic board using tweezers.

13. 13

    Remove logic board retaining screw

    1 min

    Unscrew the single Phillips #00 screw holding the bottom corner of the logic board to the internal phone frame.

14. 14

    Remove the logic board

    3 min

    Carefully lift the logic board from the top edge and tilt it out of the chassis. Ensure no remaining flex cables snag on the board during removal.

15. 15

    Position new logic board into frame

    3 min

    Lower the replacement logic board into the frame, slanting it bottom-first so ports line up properly before pressing it flush.

16. 16

    Reconnect antenna wires and flex cables

    5 min

    Snap the antenna coax heads back onto their board contacts, and reinsert all press-fit flex cables into their corresponding sockets.

17. 17

    Reconnect battery press-fit cable

    1 min

    Press the battery connector firmly down onto the motherboard terminal until it clicks into place.

18. 18

    Reattach motherboard shield and rear panel

    6 min

    Snap the motherboard shield back on, reinstall its screws, apply new pre-cut adhesive, and press the back cover firmly onto the frame.
