CyanogenMod 12 - 12.1 - 13 or any other custom ROM (based on Android Lollipop) with Theme Engine is required!
Notes:
Currently the CM Theme Engine is in early stages and you might experience a few bugs please don't leave a bad review. Rather send me a message and I will get it resolved ASAP.
If updating your ROM the device stucks in bootloop it's an issue caused by modifications to the Theme Engine please apply the stock system theme before updating!
