The Samsung Galaxy Note 4 SM-N910U is the Chinese variant of the device running on Samsung’s own Exynos5 chipset. The device doesn’t support LTE bands. Chainfire’s CF Auto Root works for most Samsung devices, and the Galaxy Note 4 root has also been achieved using the same root package. CF Auto Root uses Chainfire’s own SuperSU app to manage Superuser permissions for root access to apps and ADB.
Below are the rooting instructions for Galaxy Note 4 SM-N910U. Make sure you follow the instructions word-to-word for a fail-proof Galaxy Note 4 root.

Before you begin with guide instructions below, make sure your android device is adequately charged — at least 50% battery of the device.

Do not use the procedures discussed here on any other device of Samsung or any other company. You have been warned!
