Nokia G310 5G Screen Assembly Replacement

Difficulty

Moderate

Steps

Time Required

1 - 2 hours

Introduction

Use this guide to replace a broken screen on your Nokia G310 5G.

This guide is written for the genuine Nokia G310 5G screen assembly. The assembly consists of the screen and midframe together as one part. Make sure you have the correct part before you begin this repair.

Note: This procedure requires transferring your phone's internals into the new assembly.

For your safety, turn on your phone and allow the battery to discharge below 25% before starting this procedure. This reduces the risk of fire if the battery is accidentally damaged during the repair. If your battery looks puffy or swollen, take extra precautions.

Tools

Parts

Step 1

Power down your phone and unplug any cables.
Insert a SIM eject tool, bit, or a straightened paper clip into the small hole on the SIM card tray on the upper left edge of the phone.
Press firmly to eject the tray.

Step 2

Remove the SIM card tray.
When installing either a SIM card or a microSD card, make sure they're in the correct orientation and sitting completely flush with the edges of the tray before reinserting the tray into the phone.

Step 3

The back cover is held in place by plastic clips.
Insert an opening pick under the small notch in the SIM card tray slot.

Step 4

Position the opening pick at a steep downward angle between the back cover and the screen assembly.
Slide the opening pick down the left edge of the phone to release the plastic clips.

Step 5

Turn the opening pick around the corner and continue to slide it along the bottom edge to release the plastic clips.

Step 6

Slide the opening pick up the right edge to continue releasing the plastic clips.

Step 7

Slide the opening pick along the top edge to release the remaining plastic clips.
Don't try to fully remove the back cover just yet, as it's still connected with a cable.

Step 8

With the phone laying screen-side down, carefully lift the right edge of the back cover, opening it like a book.
Take care not to strain or tear the attached fingerprint reader cable during this procedure.
Lay the back cover next to the phone.

Step 9

Use a Phillips screwdriver to remove the 3.8 mm‑long screw securing the fingerprint reader bracket.

Step 10

Use a pair of tweezers or your fingers to remove the fingerprint reader bracket.
Take care not to puncture the battery with sharp tools—a punctured or creased battery may leak dangerous chemicals or cause a fire.
During reassembly, make sure to slide the bracket's edge back into its slot under the motherboard cover.

Step 11

Use the pointed end of a spudger to disconnect the fingerprint reader by prying the connector straight up from its socket.
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.
Remove the back cover.

Step 12

A white sticker might cover one of the top screws. Pierce through it with the tip of your screwdriver or use a pair of tweezers to remove it.
Use a Phillips screwdriver to remove the ten 3.8 mm-long screws securing the motherboard cover.

Step 13

The motherboard cover is further held in place by plastic clips.
Insert an opening pick under the right edge of the motherboard cover.
Twist the opening pick to release the plastic clips.

Step 14

Use a pair of tweezers or your fingers to remove the motherboard cover.

Step 15

Use the flat end of a spudger to disconnect the battery cable by prying the connector straight up from its socket.

Step 16

A white sticker might cover one of the top screws. Pierce through it with the tip of your screwdriver or use a pair of tweezers to remove it.
Use a Phillips screwdriver to remove the eight 3.8 mm-long screws securing the loudspeaker.

Step 17

Insert an opening pick underneath the top right edge of the loudspeaker.
Avoid pushing down at a sharp angle, or you risk damaging the interconnect ribbon cable underneath.
Twist the opening pick to release loudspeaker from the plastic clips holding it in place.

Step 18

Use a pair of tweezers or your fingers to remove the loudspeaker.

Step 19

Use the flat end of a spudger to disconnect the interconnect cable by prying the connector straight up from its socket.
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.

Hello there, I have damaged the interconnect cable during the screen replacement process, do you offer replacement cables for sale?

Step 20

Use a spudger to disconnect both antenna cables by prying their connectors straight up from the sockets on the motherboard.

Step 21

Use a pair of tweezers or your fingers to lift the antenna cables out of their recess in the frame.
During reassembly, connect the white antenna cable to the motherboard before connecting the black antenna cable. Then reseat the antenna cables into their recess.

Step 22

The charging port assembly is held in place with mild adhesive.
Insert the flat end of a spudger underneath the top right edge of the charging port assembly.
Pivot the charging port assembly up until you can grip it with your fingers.

Step 23

Use a pair of tweezers or your fingers to remove the charging port assembly.

Step 24

The vibration motor is held in place with mild adhesive.
Insert the flat end of a spudger into the small recess on the upper right side of the vibration motor.
Pivot the spudger up to pry up the vibration motor off of the adhesive securing it underneath.
During reassembly, you can reuse the old adhesive if it's still sticky. If not, replace it with new custom cut adhesive, such as Tesa Tape.

Step 25

Use a pair of tweezers or your fingers to remove the vibration motor.

Step 26

Use the flat end of a spudger to disconnect the display cable by prying the connector straight up from its socket.

Step 27

Use the flat end of a spudger to disconnect the interconnect cable by prying the connector straight up from its socket.
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 29

Insert the pointed end of a spudger underneath the bottom right corner of the motherboard.
Pry the motherboard up until you can grip it with your fingers.

Step 30

Grip the motherboard on the right edge using a pair of tweezers or your fingers.
Remove the motherboard.
During reassembly, apply small dabs of thermal paste to the marked areas on the new screen assembly. Follow this guide to prepare the motherboard and apply the paste.

Step 31

The earpiece speaker is secured to the frame with mild adhesive.
Insert the flat end of a spudger underneath the bottom left corner of the earpiece speaker and pry it out of its recess.
Remove the earpiece speaker.
During reassembly, make sure the gold contact springs on the earpiece speaker are facing up and oriented closer to the bottom edge.

Step 32

Be extra careful to not puncture, bend, or deform the battery during the next few steps—a damaged battery may leak dangerous chemicals or cause a fire.
Use your fingers to peel the two outer adhesive tabs off of the battery.

Step 33

The battery is secured to the frame with adhesive. Pull tabs are provided to separate the adhesive and remove the battery.
Use your fingers to peel the center green pull tab off of the battery.
Using one hand to hold the phone steady, use your other hand to slowly and steadily lift the center green pull tab up to separate the adhesive securing the battery underneath.
If the green pull tab rips, use the outer clear tabs instead.
If you have any difficulties with stubborn battery adhesive, you can contact Nokia's phones support.

Step 34

Peel the battery off of the adhesive film and remove it.
Don't reinstall a damaged or deformed battery, as doing so is a potential safety hazard. Replace it with a new battery.

Step 35

Grab the bottom right edge of the leftover adhesive film and pull it towards the top of the phone with steady force to remove it.
During reassembly, follow these instructions to apply a new battery adhesive film:
Remove the battery adhesive film from its liners and apply it to the battery.
Align the bottom edge of the battery (the edge without adhesive) with the bottom edge of the recess.
Lower the battery down and press firmly to secure it in place.

Step 36

The interconnect cable is lightly adhered to the frame.
Grab the bottom of the interconnect cable and peel it up towards the top of the phone to remove it.
During reassembly, realign the interconnect cable with the etched-in markings on the frame. Before reinstalling the motherboard, make sure the interconnect cable’s top connector is at approximately the same height as the display cable next to it.

Step 37

Only the screen assembly remains.
During reassembly, compare your new replacement assembly to the original part:
If your part comes with battery adhesive pre-installed, remove its plastic liners before continuing to the previous step.
If your part has no battery adhesive, remove the clear liner on the pre-cut battery adhesive and apply the sticky section to the battery well. Remove the opaque liner before continuing to the previous step.
If you're reusing your original battery, carefully inspect it for any signs of physical damage. If it's bent, creased, dented, or scratched, replace it with a new battery. Installing a damaged battery is a safety hazard.

After replacing the screen myself, the phone stopped receiving the network. I had to throw it away and buy a new phone. Waste of money for screen

Igor Komarov -

Hello Igor, sorry to hear that you experienced issues following your repair. It sounds like the issue might have been caused by the antenna cable being damaged or disconnected. In these cases, we recommend physically reseating the connectors of the antenna cable on both motherboard and daughterboard as well as checking the cable and connectors for signs of damage. If this doesn't help, you can contact Nokia's phones support to get further support.
