Steps

Time Required

40 - 50 minutes

Introduction

Use this guide to replace the daughterboard in your Motorola Moto G60S.

Before you begin, download the Rescue and Smart Assistant app to backup your device and diagnose whether your problem is software or hardware related.

The daughterboard and USB-C charging port are soldered together; replacing one component means replacing both.

You'll need replacement adhesive to complete this repair.

Tools

Parts

Tesa 61395 Tape

Step 1

Before you begin, discharge your battery below 25%, as a charged lithium-ion battery can be dangerous if accidentally punctured.
Power off your phone and unplug any cables.

Step 2

Insert a SIM eject tool, bit, or straightened paperclip into the SIM card tray hole on the left edge of the phone.
Push the SIM eject tool into the hole to eject the SIM card tray.
Remove the SIM card tray.

Step 3

Heat an iOpener and apply it to the back cover's right edge for two minutes.
A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the display and internal battery are both susceptible to heat damage.

Step 4

Flip your phone over so the display is facing up.
Apply a suction handle to the middle of the display's left edge, as close to the edge as possible.
Place the tip of an opening pick in the small gap between the back cover and the display.
Pull up on the suction cup with a strong, steady force and push the opening pick down at a 45 degree angle until it slides into the gap between the back cover and the display.
If you're having a hard time inserting the pick, reheat the adhesive with an iOpener and try again.

Step 5

Both adhesive and clips secure the back cover.
During steps that involve sliding the opening pick, keep it angled down at a 45 degree angle.
Slide the pick along the left edge down to the bottom left corner, and then up to the top left corner, to release the clips and slice the adhesive.
Leave the pick inserted in the top left corner to prevent the adhesive from resealing.

Step 6

Flip your phone over and apply a heated iOpener to the back cover's top edge for two minutes.

Step 7

Flip your phone over and rotate the pick around the top left corner.

Step 8

Slide the pick along the top edge to release the clips and slice the adhesive.
Leave the pick inserted in the top right corner.

Step 9

Flip your phone over and apply a heated iOpener to the back cover's left edge for two minutes.

Step 10

Flip your phone over and rotate the pick around the top right corner.

Step 11

Slide the pick along the right edge to release the clips and slice the adhesive.
Leave the pick inserted in the bottom right corner to prevent the adhesive from resealing.

Step 12

Flip your phone over and apply a heated iOpener to the back cover's bottom edge for two minutes.

Step 13

Flip your phone over and rotate the pick around the bottom right corner.

Step 14

Slide the opening pick along the bottom edge to release the clips and slice the adhesive.

Step 15

Flip your phone over and apply a heated iOpener to the fingerprint sensor on the back cover for two minutes.

Step 16

Adhesive secures the fingerprint sensor to the back case.
A fragile cable secures the fingerprint sensor to the motherboard. Be very careful during this step to avoid damaging the cable.
Press down on the fingerprint sensor with the flat end of a spudger or your finger.
While pressing down on the fingerprint sensor, gently pull up the bottom edge of the back cover until the sensor detaches.

Step 17

Lift the back cover up and remove it.
If the back cover is still stuck to the frame, slide an opening pick around the entire perimeter until the cover separates completely.
During reassembly:
This is a good point to test your phone's functionality before sealing it up. Use this guide to run a hardware test. Be sure to power your phone back down completely before you continue working.
Apply new adhesive to the perimeter of the underside of the back cover after cleaning the relevant areas with isopropyl alcohol (>90%) and a micro-fiber cloth.

Step 18

The fingerprint reader is secured to the motherboard cover with light adhesive.
Insert the flat end of a spudger under the fingerprint sensor.
Gently pry up and detach the fingerprint sensor from the motherboard cover.
Don't try to remove the fingerprint sensor yet, as it's still attached to the motherboard by a delicate ribbon cable.

Step 19

Use a Phillips screwdriver to remove the seven 3.9 mm screws securing the motherboard cover.

Step 20

The motherboard cover is secured with tight clips.
Insert the flat end of a spudger in the gap between the frame and the bottom left corner of the motherboard cover.
Lift straight up with the spudger to release the clips securing the motherboard.
Don't pry against the battery, as this could damage it.
This may take take a few attempts. It you're having trouble, try gripping the spudger closer to the flat end.
During reassembly, press down around the perimeter of the motherboard cover to engage the clips.

Step 21

Pull the motherboard cover towards the top of the phone to remove it.
Make sure to avoid the fingerprint sensor cable when removing the cover, as it can easily rip.

Step 22

Use the flat end of a spudger to pry up and disconnect the battery cable's press connector.
To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Don't press down on the middle. If the connector is misaligned, the pins can bend and cause permanent damage.

Step 23

Use a Phillips screwdriver to remove the seven 3.9 mm screws securing the daughterboard cover.

Step 24

Adhesive lightly adheres the graphite film to the battery.
Insert the pointed end of a spudger under the graphite film on the left side of the daughterboard cover.
Lift up and detach the graphite film from the battery.

Step 25

Insert an opening pick between the top left edge of daughterboard cover and the frame.
Pry up with the opening pick to release the clips securing the daughterboard cover.
During reassembly, press down around the perimeter of the daughterboard cover to engage the clips.

Step 26

Use tweezers or your fingers to remove the daughterboard cover.

Step 27

Use angled tweezers to grip the antenna's black coaxial connector, as close to the connector head as possible.
Lift straight up to disconnect the cable.
Be gentle when disconnecting the cable, as it's very easy to tear the socket from the daughterboard.
Repeat the disconnection procedure on the white antenna cable.
To reattach coaxial connectors like these, align the connector over its socket and press down with the flat end of a spudger. The connector should snap into place. This can be tricky and may take a few tries.
During reassembly, make sure the antenna cables are in their groove on the edge of the phone.

Step 28

Use the flat end of a spudger to pry up and disconnect the interconnect cable's press connector from the daughterboard.

Step 29

Insert the pointed end of a spudger in the circular cutout on the middle of the top edge of the daughterboard.
Pry up until you can grip the daughterboard with your fingers or tweezers.

Step 30

Lift the top edge of the daughterboard up with tweezers or your fingers and pull it towards the top of the phone to remove it.
During reassembly:
Make sure the interconnect and antenna cables are out of the way so they don't get stuck under the daughterboard.
Reinsert the daughterboard at a downward angle to position the USB-C port back into its recess.
