The CM 12.0 Ghost (Lollipop) is an unofficial build of CyanogenMod 12 ROM for Moto X 2013. It is a very early build, which means it is experimental and unstable, so it may contain bugs. However, Android fans who want to go crazy and play with the new Android Lollipop can flash the rom and enjoy it. Requirements: a) Moto X bootloader must be unlocked b) Moto X must be rooted and custom recovery like CWM or TWRP installed. c) Backup every important data as well as create a Nandroid backup from recovery, so you can restore them in case anything goes wrong.
