Earlier today LG began rollout for the much awaited Marshmallow update for its 2014 flagship, LG G3.

The update first leaked on Twitter by @utoprime with a download link for the full KDZ firmware file of the LG G3 Marshmallow update with software version 30B.

The update is coming to the International variant of LG G3 (D855) first. If you haven’t yet received the update, you can manually install it using either the full stock KDZ firmware OR grab the custom recovery flashable ROM files provided by autoprime.

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.

Grab SuperSU v2.65 from the download link below, and follow the simple instructions below to root G3 Marshmallow firmware.
