LG K92 5G Root, Bootloader Unlock, TWRP, Custom ROM lmk920am

K92 is the last and only K series 5G device from LG. As LG is shutting down its cellphone division, we won’t see another LG K series smartphone in the future.

A few years ago, it was possible to root an LG smartphone in one click without using a computer. Rooting apps like Kingroot were able to root the phone even with a locked bootloader. This worked until Android Lollipop. Since Marshmallow, the android security is tightened.
