The LG G3 has finally received its Android 6.0 Marshmallow update with LG’s touches and customizations. You can check for the OTA update and see if the update is available on your phone. If it is not eligible yet, then you can download the Marshmallow KDZ file and manually flash it on your phone. Follow this guide to flash Marshmallow KDZ on LG G3.
If you aren’t happy by updating to Marshmallow alone, than you can root your phone. Even though Marshmallow is only a few days old, root can be gained easily on the LG G3 D855. When you root you phone, you gain root access thanks to SuperSU which allows other apps to access system files.
