How to Update LG G2 to Android 6.0.1 Marshmallow using CM13

This guide will help you update LG G2 model d802 to Android Marshmallow 6.0.1 using CyanogenMod 13 nightly custom ROM.

LG G2 was an amazing Android smartphone having fast processor and good camera but now it’s quite old as it was officially released back in 2013 and LG has stopped releasing official updates for its old flagship. But you don’t have to worry about the latest updates for the LG G2 as you can still have Marshmallow on LG G2 using any Custom ROM.
