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.

Do you know where the internal memory chip is located?
Is it possible to get schematics for lg v20 motherboard?
Did you find it? I need it too :(
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!
