Motorola Moto E4 Plus LCD and Digitizer Replacement

Difficulty

Moderate

Steps

Time Required

1 - 2 hours

Introduction

Use this guide to remove the LCD and digitizer of your Motorola Moto E4 Plus.

Before disassembling your phone, discharge the battery below 25%. The battery can catch fire and/or explode if accidentally punctured, but the chances of that happening are much lower if discharged.

This guide replaces only the display while leaving the original frame and battery in place. Some replacement screens for this phone come pre-installed on a new frame (a.k.a. chassis), which requires following a very different procedure. Make sure you have the correct part before starting this guide.

Tools

Parts

Step 1

Power off your phone before beginning disassembly.
Insert the edge of the spudger into the notch on the bottom right corner of the phone.
Twist the spudger to start releasing the back cover from the phone.
Slide the spudger along the bottom edge to separate the back cover from the phone.

Step 2

Lift the phone unit out of the back cover.

Step 3

Remove the nineteen 3.2 mm long T3 screws securing the plastic midframe.

Step 4

The plastic midframe is still held in place with clips.
Insert the flat end of a spudger into the midframe seam at the bottom left corner of the phone (near the microphone hole).
Twist the spudger to release the plastic clip.
Repeat the process for the clip near the top right corner of the phone.

Step 5

Lift the bottom edge of the plastic midframe upwards until the clips along the top edge release.
Remove the plastic midframe.
To reattach the plastic midframe, line up the midframe to the phone and squeeze along the edges to engage the clips.

Step 6

Use the point of a spudger to pry up and disconnect the battery connector from its motherboard socket.

Step 7

Use the point of a spudger to pry up and disconnect the display cable from its motherboard socket, near the bottom left corner of the motherboard.

Step 8

Use the point of a spudger to pry up and disconnect the antenna cable from its motherboard socket.

Step 9

Use the point of a spudger to pry up and disconnect the interconnect cable from its motherboard socket.

Step 10

Remove the two black 3.2 mm long T3 screws securing the motherboard.

Step 11

Grasp the motherboard by the top corners and lift it out of the phone.
Remove the motherboard.

Step 12

Use the point of a spudger to pry up and disconnect the antenna cable from its daughterboard socket.

Step 13

Use the point of a spudger to pry up and disconnect the interconnect cable from its daughterboard socket.
Pry up and disconnect the fingerprint sensor cable next to it from the daughterboard.

Step 14

Remove the two 3.2 mm long T3 screws securing the daughterboard.

Step 15

Insert the point of a spudger under the bottom right corner of the daughterboard and pry up to loosen the daughterboard.

Step 16

Insert the point of a spudger underneath the vibration motor and pry upwards to loosen it.

Step 17

Grasp the daughterboard by the edges and lift it out of its recess.
Remove the daughterboard. The vibration motor will be attached to it.

Step 18

Use the point of a spudger to pry up and disconnect the display grounding cable from the frame.
When you install the replacement cable, be sure that it is properly positioned with the gold side facing up.

Step 19

Prepare an iOpener and apply it to the display for at least two minutes to loosen the adhesive underneath.

Step 20

Once the screen is warm to the touch, apply a suction cup near the top edge of the phone below the earpiece speaker.
If the phone's screen is cracked, the suction cup may not stick. Try lifting it with strong tape, or superglue the suction cup in place and allow it to cure so you can proceed.
Pull up the suction cup, and insert the tip of an opening pick under the display where the earpiece speaker is located.
Slide the opening pick to the top left corner of the phone to cut the adhesive.

Step 21

Insert a second opening pick and slide it to the top right corner of the phone.

Step 22

If cutting becomes too difficult, reheat and reapply the iOpener to the screen.
Slide the opening pick from the top right corner down the right edge of the phone and cut the adhesive with it.
While cutting, make sure the pick slides under the display panel and not just between the display and the front glass.
Continue sliding the opening pick around the bottom right corner of the phone.

Step 23

Slide the opening pick along the bottom edge of the phone and cut the adhesive.
Be careful around the home button, inserting only the tip of the opening pick to prevent damaging the button.

Step 24

Repeat the previous heating and cutting procedure on the left edge of the phone to cut the remaining adhesive.
Don't completely remove the display yet! The fingerprint and display flex cables are still threaded through the midframe.

Step 25

Carefully thread the display cable at the top and the fingerprint sensor cable on the bottom through their gaps in the midframe.
Remove the LCD and digitizer.
Remove any remaining adhesive from the midframe, and clean the glued areas with isopropyl alcohol and a lint-free cloth.
In case your new LCD and digitizer doesn't include the fingerprint sensor, you will need to continue with the fingerprint sensor guide to transfer it to the new LCD and digitizer.
Carefully compare your replacement part with your screen. You may need to transfer minor parts such as earpiece bezel to the new part.

Hi Franck,

You can use the pre-cut adhesive, or double-sided Tesa tape.
