I googled for CM ROM for my note 4 n910u. Google gave me a youtube link pertaining to this thread (see below). However, the thread title shows that the rom is only available for N910c. I wonder if the rom works with n910u as the youtube links says that it works with All exynos note 4.
and the blog post
A brave and kind soul has compiled a working RR build! I have tested it and it boots! https://plus.google.com/+JanLucaNeumann/posts/Hrio7zHobe6

I don't think there's much of a point in these builds honestly.New build is up! MEGA
In this build is fixed GPS & Network operator selection.
This build it's not the same build(reuploaded) from rayman "build3"!
It is recompiled from the official cyanogenmod sources with new fixes and uploaded.
For everyone that asks: The build is stable and all is working fine. My server just compiles from the source code and I am sharing it. Official maintainer for the device is RaymanFX.
