An unofficial CyanogenMod 12.1 build based on Android Lollipop v5.1.1 has been released for the OnePlus 2 by recognised XDA developer, Grarak.

As its name suggests, the build is in its beta stage and might not have all the features functioning smoothly. Some forum members, who have successfully ported the beta firmware in the new phone, claim to have a hassle-free flashing experience, although there were a few hiccups here and there.

"Just flashed the ROM and it boots up nicely. Very fast / highly responsive. Looking forward to WiFi & Cell Support," noted a forum member.
