We have already seen the screenshots of an Android 5.0 Lollipop update running on the LG G3 and now, here we got to know that a working ROM that you can install on your phone and try it out yourself, courtesy of XDA user upload (early build, F400S only).
The user also posted the the firmware update is not a final version, so before trying it on the update, make sure to backup your data. Just think about bricking your phone, but if you are aware of consequences.
Although the ROM is an early build and not very stable. Also, it is only intended for the F400S variant of the G3. If you have it, and don’t mind bricking or potentially making it unusable, then you can try installing the update from the source link below.
Or, simply watch this video below.
