The Samsung Galaxy Note 5 smartphone has the luxury of having the CF-Auto-Root tool available which device owners can flash using the Odin flashing tool, and it acts as a handy one-click rooting tool that installs and enabled SuperSU on the smartphone. The way CF-Auto-Root works has changed with the Android 6.0 Marshmallow updates providing updated security measure by the Android developers which ended up working out Chainfire’s favor in many respects due to the /system partition no longer needing to be altered. That has opened up new avenues that we have not seen before for people to keep root potentially after applying updates. However, it also leaves the OS vulnerable of being unrooted easier now with a factory reset being all it takes to go back to the stock ROM and not the usually flashing of an official firmware file.
- The following guide is made for the Samsung Galaxy Note 5 that comes with the SM-N920C model number when it is running on the Android 6.0.1 Marshmallow software updates. You can find out what the model number and your Android version is by tapping on the Menu > Settings > About Device menu.
- You must have a version of the Windows operating system running on your computer before you can follow this guide. You do not get the version of the Odin flashing tool in this guide to run on the MacOS or Linux distributions. Samsung developers have made the Odin flashing application to work on Windows operating systems only because it is the most popular operating system for people to run.
- You need to install a custom recovery on the Samsung Galaxy Note 5 smartphone  before you can go ahead and root it with this guide. Unlike with rooting the Android operating system, installing a custom recovery can be made using the same guide across all model numbers.
