There are basically two best LG G2 android 6 marshmallow ROMs out there. First is the bliss ROM that is one of the most customizable firmwares for the LG G2 and second is resurrection ROM. Since both ROMs come without gapps, we suggest installing them from here in case you cannot live without gapps. We still prefer using the bliss ROM as its developer offers regular updates than the resurrection ROM.
Installation instructions:
* Make sure you are rooted.
* Make sure you have a custom recovery installed. (TWRP is the preferred recovery)
* Download the latest Bliss Rom and the latest GApps package.
* Boot into recovery.
* Perform a FULL factory wipe and wipe/system and dalvik cache as a precaution
* Flash Bliss Rom
* Flash Google Apps package (for 6.0!)
* First boot may take up to 10 minutes
