Introduction

Replacing the motherboard is last resort if the device is not functioning correctly. Symptoms that indicate a need for this replacement include an inability to send or receive messages, delayed responses to button-commands, or freezing or glitching screens.

The motherboard is connected to the rest of the device by a few different cables that cannot be severed, so precision is crucial.

What you need

Step 1

              Nylon Strap
  • Place the device on a level surface with the back hard case facing up.

Step 5

  • Using the precision tweezers with the round tips, detach the battery connector from the motherboard.
  • Disconnecting the battery stops the flow of power into the motherboard. This is for your own safety.
  • If utilizing this guide as a prerequisite to replacing the motherboard, it is crucial not to damage the cable connecting the battery to the motherboard. When the new motherboard is introduced, it will need to be reconnected with that cable.

Step 6

              Battery
  • After removing the back hard case, users can access the battery on the inside of the back hard case.
  • Take the iFixit opening tool and insert it into the small crevices on each side of the battery. Once inserted, apply pressure downward in order to lift the battery up. Repeat on all 3 corners.

Step 7

  • Create leverage by inserting the opening tool underneath the battery. Lift the battery up until it detaches from the case, then remove the battery entirely.

Step 8

  • Then using the precision tweezers with the round tips, lightly pull the battery out from the case.
  • The battery is attached to the back hard case with an adhesive.
  • Dispose of the lithium ion battery in a safe manner in order to prevent electrical hazards. Keep the battery dry and cool.

Step 9

              Motherboard
  • Use the T5 screwdriver to remove each 5 mm screw.
  • Next, use the precision tweezers with the round tips to disconnect the black antenna wire from the motherboard.
  • Do not sever the black wire! This may render the device unusable, even when a new motherboard is introduced.

Step 10

  • Using the precision tweezers with the round tips, gently pull up the thick red strip until it pops off of the motherboard.
  • Using the same tweezers, gently pull the thin red strip towards the end of the case in order to detach it from the motherboard.

Step 11

  • Using the precision tweezers with the curved, pointy tips, squeeze both ends together, then insert them into the bottom left hole of the motherboard. Next, gently lift up the tweezers and pull out the motherboard.
  • Once you’ve pulled the motherboard halfway out, use the precision tweezers, or your fingers, to pull the motherboard out completely.
  • Be careful not to sever or damage any piece surrounding the motherboard, including the screen located beneath it! If any of the strips or cables are damaged, it may prevent the successful installation of a new motherboard.
