Here are links to flashable boot.img's that fix SuperSU:
Holy wall of text, Batman!
Today I've added the first Note4 (Asia only) models to the list: SM-N910C, SM-N910U, SM-N9106W - http://forum.xda-developers.com/note-4/orig-development/sm-n910-cf-auto-root-t2897428
A whole bunch of devices' CF-Auto-Roots have been updated from older firmware bases to 4.4.x firmware bases. Means these CFAR's work again on the latest bootloaders, primarily.
This update primarily fixes some L-related issues.
This relatively minor update fixes a number of reported crashes and bugs, updates the timelapse module, adds some Android 4.4+ KitKat specific compatibility, and supports Android Wear.
I've just uploaded v3.10 of StickMount to the Play store, bringing compatibility with the Android "L" Preview. That's it, really.
I've just uploaded v2.50, with the primary new feature being Android "L" Preview compatibility.
