As for root access, well, thanks to Chainfire’s systemless root with auto boot patcher, it’s now effortless to get root on most Marshmallow firmwares from most manufacturers. And the LG G3 Marshmallow firmware is definitely one.

You can root LG G3 Marshmallow 30B update by simply flashing the latest SuperSU v2.65 beta zip from TWRP recovery. The flashing process will automatically patch the boot to allow systemless root, and then install root binaries without modifying the system partition.
