LG G6 Motherboard Replacement
This guide will walk you through removing or replacing the LG G6 motherboard.
Step 1 | Rear Glass Panel
Be extremely cautious when cutting through adhesive near the fingerprint sensor to avoid damaging its delicate cable.
- Consult the first photo for reference on the rear glass panel's backside, noting the clearance between the panel and the ribbon cable beside the fingerprint sensor.
- Pry carefully, aiming for the left side of the fingerprint sensor as shown in the third photo from the outside.
- Avoid inserting an opening tool more than 3 mm into the phone in this area to prevent damage or tearing the fingerprint sensor cable.
Step 2
Apply heat to the backside of the G6 using a hairdryer, heat gun, or an iOpener to loosen the adhesive holding the rear panel in place.
- Target the lower edge of the device and maintain heat for about a minute to effectively soften the adhesive.
Step 3
Secure a suction cup to the rear panel, near the heated edge.
Step 4
Careful not to apply excessive force, as the rear glass panel is fragile.
- Prop up the phone's heated edge on a 0.5 inches (13 mm) thick object like an eraser to angle for easier tool insertion.
- If no prop available, perform at desk/table edge with caution to achieve same angle of entry.
Significant force may be required; if stuck, reapply heat, let cool slightly, and try again.
- Lift rear panel's bottom edge with suction cup, creating a gap between panel and frame.
- Insert flat end of opening tool into the gap once a slight gap is created.
Step 5
Slide a opening tool back and forth along the phone's bottom edge to cut through the adhesive.
- The adhesive should be completely broken once a suitable gap has formed.
- Insert an opening pick into the gap to prevent re-bonding, then remove the tool.
Step 6
Apply heat to each edge as needed before slicing.
- Use multiple opening picks, leaving one on each side after finishing.
- Slide an opening pick along the left phone edge to slice the adhesive.
Step 7
Insert the opening pick back into the bottom edge of the phone.
- Slide it up along the right edge, carefully separating the adhesive.
Step 8
Be cautious when cutting through adhesive near the camera.
- Slide an opening pick along the top edge to separate remaining adhesive.
Step 9
Use an opening pick to carefully lift the rear glass panel.
- Continue prying until the panel is completely removed.
Step 10
When reusing the rear glass panel, use tweezers to remove remaining adhesive from both the panel and chassis.
Clean adhesion areas with at least 90% isopropyl alcohol and a lint-free cloth, swiping only in one direction.
- Test your repair by turning on your phone before installing new adhesive.
- Peel liner from replacement adhesive, align it with the back of the phone, and press into place.
- Remove all liners and reattach rear glass panel.
Apply strong pressure to your phone for several minutes after installing rear panel, or use a stack of heavy books.
- If reinstalling without replacing adhesive, remove large chunks that may prevent flush fit.
- After installation, heat the panel and apply pressure for a secure hold.
Note: Phone will not be waterproof if using residual adhesive alone.
Step 11 | Battery Disconnect
Remove the four Phillips screws securing the lower antenna shield.
- Disconnect the shield and set it aside.
- Dispose of the Warranty Void If Removed sticker responsibly.
Step 12
Insert the point of a spudger into the small gap between the lower antenna shield and the metal frame.
- Gently pry up the antenna shield.
- Remove it from the phone completely.
Step 13
Remove the seven Phillips screws securing the upper antenna shield.
Step 14
Insert the flat end of a spudger into the gap between the upper antenna shield and phone chassis.
- Pry up, releasing the clips holding the shield in place.
- Remove the upper antenna shield and wireless charging coil.
Step 15
Insert a spudger between the press connector and the ribbon cable.
- Pry gently to release the press connector from its mating half.
- The battery should now be disconnected.
Step 16 | Motherboard
Insert a SIM removal tool or SIM removal bit into the hole opposite the volume buttons and press to release the SIM/MicroSD card tray.
- Remove the SIM/MicroSD tray.
Do not skip this step — motherboard removal is impossible without first removing the SIM/SD tray.
Step 17
Position the spudger so that its flat end is between the two press connectors.
- Lift upwards with a gentle rocking motion to separate the press connectors from the motherboard.
Step 18
Remove the adhesive strip securing the motherboard to the vibration motor.
Step 19
Hold the motherboard by its top edge, which is near the camera area.
- Lift it upward and outward from the phone's casing.
