Android 4.3 in Samsung devices adds a quite annoying, and not much needed feature – Knox. Fortunately, there is a way to get rid of it by flashing a stock, rooted Knox-free ROM. The firmware is stock, but comes pre rooted and Knox free.
Other than that, there is no difference between this and the ones that comes with your Note 10.1 2014. Flash the ROM in recovery.
Download the ROM, put it on your SD card, and flash them in recovery. Do not use ODIN to flash it.
