Download and Install Firmware on LG G6

LG announced its first flagship for 2017, the LG G6 on in March. The LG G6 comes with a 5.7 inch QuadHD+ IPS LCD display with an unusual 18:9 aspect ratio. The idea is to offer more real estate — just over 80 percent screen-to-body ratio in the case – in a compact form factor. It powered by a 2.35GHz quad-core Qualcomm Snapdragon 821 processor with Adreno 530 GPU and 4GB of RAM. The 64 GB of onboard storage is expandable via a microSD card up to 256GB. A 13 megapixel rear facing camera and a 5 megapixel front-facing shooter consist of the camera setup. The phone runs LG UX 6.0 on top of Android 7.0 Nougat. All of this is powered by a 3,300mAh battery.

LG G6 obviously be receiving a lot of third-party developer support and modders would want the best performance out of their device. Which usually means installing custom ROMs, kernels, and other mods.
