Here’s disassembly/teardown of LG G6 and general guide on how to fix parts such as replacing screen, camera, etc…etc…
My recommended tools for LG G6 disassembly/screen repair:
- #00 Screw driver – Link
- Suction cup/car mount – Link
- Guitar Picks – Link
- Plastic Pry Tool – Link
- Box Cutter Knife – Link
- Heat Gun – Link
Step 1. First you will want to use the heat gun to heat up the back of the phone. Then put your suction cup towards the bottom of the phone.
Step 2. Apply some more heat gun to the bottom of the phone. Go ahead and heat up the bottom of the phone then stick your sharp knife between the gap of the back glass and the phone.
Step 3. Next, take a guitar pick and slowly move up the sides. Apply some more heat using the heat gun and repeat the process until the whole back glass comes off.
Step 4. There are 11 screws, unscrew all of them.
Step 5. Also, don’t forget to take the sim card tray out! Slowly pull off the wireless charging unit which is stuck on with adhesives. Carefully pull the top part of the plastic assembly out. If it gets stuck, try wiggling on the bottom right of it and it should pull out.
After that, the bottom speaker assembly should also easily pop out.
Step 6. The battery is stuck with adhesive. To get it out, first disconnect the battery connector, heat it with heat gun then pry out with any flat plastic tool.
Step 7. Once 3 connectors are disconnected, the motherboard will easily slip out.
For screen repairs, I do highly recommend you to buy an LCD digitizer w/ frame, which should cost $50-60 more but you will be able to re-assemble your phone without losing waterproofing. If you don’t care about waterproofing, you can also replace just the LCD itself, check out my friend JerryRigEverything’s video on that here.
To re-assemble, first you will want to clean up the thermal paste and apply new thermal paste. Go ahead and clean off all the existing thermal paste. You can use some soju or your favorite bottle of liquor to clean it.
For thermal paste, you can use PC thermal paste like Artic Silver, simply put a small drop of it. Carefully put the motherboard back on. Next, connect the front camera connector. Then connect the two connectors also at the bottom.
Next, put the battery back in and also connect the battery connector.
Carefully place the top plastic assembly back on first. It should all snap into place easily. Then put the bottom speaker assembly back on. This should also snap into place.
Lastly but not least, go ahead and screw all the screws back in, that is 11 screws total.
Now, if you absolutely need waterproofing, you will want to replace the adhesives with new ones and make sure to apply them perfectly. For now, I am just going to re-use the adhesive. Carefully put the back cover on, apply some heat gun and keep pressing down on the back cover until it is flush.
Power on your phone and if it power up, congrats! Once turned on, check and make sure everything is working such as 4G LTE, front camera, back camera, etc…etc…
