The CF-Auto-Root tool is always flashed with the Odin flashing tool–an app made for Windows computers that is also allegedly made by Samsung developers that was leaked but never saw an official release. The Odin flashing tool is the primary app used on a computer for all Samsung owners to flash all kinds of stock ROMs from official Samsung sources. It is also the app that people use to flash TWRP Recovery if they want a custom recovery.

The CF-Auto-Root tool is developed by a guy who goes by the alias of Chainfire and people love using the automatic one-click rooting tool because it is quick, easy and doesn’t involve a custom recovery. Not everyone wants to have a custom recovery installed because they might not have any interest in flashing a custom ROM, kernel, taking NANDroid backups and so forth.

REQUIREMENTS

• You must have a computer that is running on one of the versions of Microsoft Windows operating systems to use this guide. The reason being that the flashing tool requires a Windows operating system before it runs. Anyone who cannot get access to a computer that runs Windows can try settings up a Windows virtual machine from the Mac or Linux computer environment.
• The following guide is made for the Samsung Galaxy Note 3 Neo SM-N7505 model number only. Any other model number will likely get bricked when you flash this rooting file. You can check what the model number of the Samsung Galaxy Note 3 Neo by tapping on the Menu > Settings > About Device > Model Number.

BEFORE WE BEGIN

• Note that Chainfire was using the LMY47X.N7505POUDOK2 firmware build number on his Samsung Galaxy Note 3 Neo SM-N7505 smartphone when he developed the CF-Auto-Root tool that is found in this guide. Nobody needs to be running on the same firmware build number as he was when he created the rooting package. As long as you are running on Android 5.1.1 Lollipop and have the SM-N7505 model number version of the Samsung Galaxy Note 3 Neo smartphone, then the guide should work well for you.
• You need to unlock the Developer Options menu on the Samsung Galaxy Note 3 Neo smartphone if it is not already unlocked by tapping on the Menu > Settings > About Device > Build Number at least seven times. Do not stop tapping on the build number until it shows a message on the display saying that you are using the device as a developer now.
• You need to enter the Developer Options menu and enable the USB Debugging Mode if it is not already by tapping on the Menu > Settings > Developer Options > USB Debugging Mode.
• You should install the Samsung USB Drivers on the computer if the computer does not have them already so that the Samsung Galaxy Note 3 Neo smartphone can be detected by the flashing tool.

In conclusion, that is how to root Samsung Galaxy Note 3 Neo SM-N7505 running on Android 5.1.1 Lollipop software updates by using Chainfire’s SuperSU. The Galaxy Note 3 Neo reboots by itself back into the normal mode which is the mode where you typically use the Android operating system. There is one difference you can notice when it does which is the SuperSU application that is now available from the app drawer. That SuperSU app is what the CF-Auto-Root tool just installed and enabled by flashing a modified recovery image and a modified cache image to get that done. The Note 3 Neo itself is left with the stock recovery and usual cache when the process is complete because the CF-Auto-Root tool puts everything back the way it started once it has successfully enabled the SuperSU on the smartphone. All of that is done by the time you get the message on the screen letting you know that it is going to reboot in ten seconds.
