The Samsung Galaxy Note 3 smartphone is now getting old, and it is almost certainly time to check out some custom ROMs for the device if you are one who likes to customize a device. The only way you can get a new ROM running on your Samsung Galaxy Note 3 smartphone is to install a custom recovery and root the smartphone. We can complete one of those tasks that are required below by using the CF-Auto-Root by Chainfire. As you know, using the CF-Auto-Root tool means you are going to have the Samsung Galaxy Note 3 rooted.

Once the guide is complete, you will find the SuperSU application available from your Samsung Galaxy Note 3’s app drawer. There isn’t anything you need to adjust the settings of your SuperSU. What happens is when you head over to the Google Play Store and start installing your root applications, it will normally install just like a normal app would. The difference is when you open the app, and it needs the root permissions to run.

You can expect the SuperSU application to pop up a new message on the display asking if you want to grant the rooting permissions it not. It’s important you say yes at this point or else the root apps won’t work. However, it’s also important you understand that you should not grant root access to anything that shouldn’t have it on your operating system. That means that if you get a message saying something similar to “this app wants root permissions” and you can’t see what the app is, then you cannot be granting root access. You have no idea what that might be. It could be Google, the FBI, some random kid wanting to access your message and so forth.

The CF-Auto-Root tool in this guide is based on LMY47X.N750XXUDPA2 firmware. You do not have to install the firmware on your Note 3 smartphone before you continue with the guide. The developer of the rooting exploit in this guide just gives it to use so we can use that firmware information as an indicator.
