Up until now, the only way you could get CyanogenMod on your Nexus 6 and LG G3 were downloading custom ROMs that were ported over. While these ROMs were very stable and efficient, they aren’t official. As of yesterday, Cyanogen has officially announced support for those two devices.
The Nexus 6 and the LG G3 (D855) will be receiving CyanogenMod nightlies, meaning the ROMs will be updated everyday. While this great for users, we should warn you that these ROMs are still in their infancy, meaning they aren’t the most stable. Just make sure you know what you’re getting yourself into when you are flashing new ROMs and make sure to backup your stock one. Also, the nightlies for the G3
are only on the international version are available for the international version D855 and AT&T version D850. If you try to install either of these nightlies on a device that isn’t international or AT&T, you will brick your device.
Update: The LG G3 AT&T variant (D850) has been receiving CyanogenMod nightlies dating all the way back to December 5th. Thanks for the tip Larry!
