LineageOS 14.1 is now available for the recently announced Redmi Note 5 Pro (A.K.A Redmi Note 5 for China). The LineageOS 14.1 is based on Android 7.1.2 Nougat, which is not the latest OS, but still great for Stock Android lovers.
Developer vasishath says that "Almost Everything" works in this Custom ROM including Boots, Volte, RIL (Calls, SMS, Data), Fingerprint, Wi-Fi, Bluetooth, Camera, Camcorder, Video Playback, Audio, Sensors, Flash, LED, and GPS.
You'll need an Unlocked Bootloader with TWRP recovery installed on your Redmi Note 5 Pro (How to Video Guide coming later tomorrow on our YouTube Channel). Rest of the process includes Downloading and Flashing Google Apps and LineageOS 14.1.
