Remove the rear cover by placing the plastic opening tool in the groove on the bottom left side of the LG G4 and gently prying up.
-
-
-
Place the plastic opening tool at the bottom edge of the battery and lift up. Carefully remove battery with your hands.
-
-
-
Remove the eleven 3.9 mm Phillips #00 screws found at the back of the phone.
-
-
-
Once all the screws have been removed, place the plastic opening tool in the lower left corner and firmly lift the cover up.

Detach the cover with your fingers

Remove the following four press-fit connectors with the flat edge of a plastic spudger or opening tool:
-
Front-facing camera connector.
-
Rear-facing camera connector.
-
Digitizer connector.
There is a ribbon on the left of the camera. Use spudger to lift this so that the camera is left behind. Do not fiddle with the rear facing camera.
I second that! Just unsnap the camera connector like the other two. Unsticking the camera instead is silly, when that is so much simpler. Please update this to mark the third connector to be unsnapped.
I lifted the ribbon but I can't get it to stick back down!
I tried lifting the ribbon but it didn't unsnap… it actually felt like it ripped off. I couldn't get it to “snap” back down like the other ones.

Remove the motherboard by lifting it up using the plastic opening tool and your fingers .
My LG G4 has stopped working. Was told it needs board replacement. How do I get the motherboard. I reside in Nigeria.
I realize this is over a year old, but for anyone else’s future reference you can find replacement boards on ebay. There is even a seller with brand new 700’s serial number boards (AKA the last batches available after the bootloop recalls). I think the name is “gsmplaza” IIRC; they’re based in Israel and are the only sellers selling BRAND NEW boards, not refurbished or used, so it shouldn’t be hard to find.

Use a heat gun or iOpener over the auxiliary port to soften the adhesive that secures it to the plastic housing.
I found this to be unnecessary. Mine came out easily when I shoved a small screwdriver all the way to the back and gently pulled upwards. Mine may have been loose from lots of use though.

It is possible replace the digitalizer only? Thanks
Per the LG G4 Teardown guide, the glass, digitizer, and LCD are all fused together, so you have to replace the whole assembly
Lorsqu’on remplace l’ensemble écran + LCD achetés ensemble et que l’on transfère les pièces de l’ancien cadre (caméra, vibreur…), il ne faut pas oublier de transférer également 3 petits caoutchoucs carrés noir ou gris (2 en haut de chaque coté du haut parleur, et 1 en bas à gauche de la prise jack), sinon le détecteur de proximité ne marche pas et l’écran s’éteint et le reste lorsqu’on téléphone…
C'est bien qu'on fasse cette observation. Mon technicien avait omis ces neoprenes et j'ai pu les transférés.
My tech had omitted these pads. I am super grateful someone commented that the phone would black out on a call. Problem solved!
