    • Before disassembling your phone, discharge the battery below 25%. A charged lithium-ion battery can catch fire and/or explode if accidentally punctured.

    • Insert a spudger or your fingernail under the battery at the small recess on the lower edge.

    • Be careful not to deform or puncture the battery.

    • Pry up and remove the battery.

    • Remove the sixteen 4mm Phillips #00 screws attaching the back cover to the motherboard.

    • The top and bottom frame section hold very tight to the mid frame. It is possible to pull them off with your hands. If you're not able to do so, use the following removal procedure:

    • Use the flat end of a spudger and apply pressure to one of the corners of the frame section until you create a small gap.

    • Flip the phone and insert an opening pick in the gap you created.

    • Slide the opening pick along the gap until the frame section pops out of its plastic clamps.

    People on Reddit are reporting that the V20's antennas are contained in this top piece, and removing it too forcefully can damage the 2G antenna's contacts, resulting in a loss of ability to make calls. Details and a suggested fix if this happens to you:

    • Remove the frame section.

    • Repeat this procedure with the frame section on the other end of the phone.

    • Within the top frame section there's a small silver grating that covers the speaker. This may fall out, so be careful not to lose it.

    • The loudspeaker is attached to the cover of the motherboard. Use an opening pick to pry it up.

    Be very careful with prying up the speaker or else it will break the connection to the cover.

    • The cover of the motherboard is held in its place by several plastic clamps.

    • Use an opening pick to pry up the motherboard cover at the right corner at the bottom of your phone until it pops out of the plastic clamp.

    Bonjour, en placant le médiator à l’intérieur de l’emplacement de la batterie le démontage est plus facile de l’intérieur vers l’extérieur…

    Merci pour l’info!

    In English: it is easier work your way around the inside of the battery compartment rather than around the outside. Also, the clip below the power button (i.e., top of the battery compartment) will release the whole top edge.

    • Use the flat end of a spudger to disconnect the front camera flex cable.

    • If you want to go on and remove the motherboard assembly, there is no need to remove the front facing camera after disconnecting it. However if you feel uncertain, carefully remove it with a pair of tweezers.

    • Use a pair of tweezers to carefully remove the front facing camera. Be careful to only grip the body of the camera, as the top is the sensor pcb and is only held on with glue (removal will ruin the sensor).

    • Use the flat end of a spudger to disconnect the flex cable of the left rear camera.

    • The second rear camera will come out with the motherboard since it is connected on the other side.

    • You can leave the front facing camera in its place as long as you're careful while removing the motherboard assembly. However if you feel uncertain, carefully remove it with a pair of tweezers.

    Anyone have a picture of the back of the board by the charge port

    • Use the pointed end of a spudger to lift up the motherboard assembly until you can get a good grip.

    • Carefully lift up the motherboard assembly and remove it.

    Be very careful handling motherboard. The numerous spring-type contact points can be easily bent.

Anyone knows what antenna are located in the lower bumper? Coz one metal contact, which sits right beside the earphone port, has accidentally come off the mainboard. And this contact should connect with another metal clip inside the lower bumper. It must function as some kind of antenna. But what exactly? So far I haven’t noticed anything obviously wrong with the reception after the damage, but still upset about this.

Thanks. I used this guide to help me replace the thermal paste TIM on my LG V20 H990DS… It did make the phone more stable, but didn’t fix image ghosting… Oh well. Thanks again!
