The European variants of the LG G4 took a while to get bootloader unlock like the rest of the pack. With that rom development was slowed down. CyanogenMod has finally released nightly builds for both the H811 and H815 variants of the LG G4! To install this you will need to have a custom recovery installed. Grab the Nightly from the link below. You will also need to be sure to install the Gapps package. This will give you a nice clean install of stock AOSP Android with a few optimizations and customization options!
