Rooting the Samsung Galaxy Note 3 smartphone when it is running on the Android 4.4.2 KitKat software updates can be done by flashing a one-click rooting tool called CF-Auto-Root. The way CF-Auto-Root works is a touch of genius. The rooting tool is programmed to install a modified recovery and then flash and enable the SuperSU. It then removes its modified recovery image and reflashes the stock recovery that was running before it started, so you are left with the same recovery and SuperSU enabled. It is the SuperSU that is going to give you the chance to become the root user.
- You must have the Samsung Galaxy Note 3 smartphone that comes with the SM-N9008 model number to use this guide.
- You need to have a computer that is running a version of the Windows operating system before you can follow this guide.
BEFORE WE BEGIN
- Chainfire had the KOT49H.N9008ZMUENG4 firmware build number running on the Samsung Galaxy Note 3 SM-N9008 smartphone when he developed the version of the CF-Auto-Root tool that you find in this guide. That does not mean you need to be running on the same firmware build number that he was when you follow this guide and flash the rooting file. The CF-Auto-Root package in this tutorial will root the SM-N9008 model number when it is running on any version of Android 4.4.2 KitKat software updates, including all of the firmware versions that might be available with that software.
- If you flash the rooting file available in this guide, and it causes the Samsung Galaxy Note 3 not to boot after the flashing, you need to let the developer know by posting the recovery image of the firmware you are running on the CF-Auto-Root tool thread made at the XDA-Developers website . He will see your message and use the recovery image file to apply the changes that make the rooting file in this guide work again.
- Unlock the Developer Options menu on the Samsung Galaxy Note 3 smartphone  so you can then enable the USB Debugging Mode on the device.
- Install the Samsung USB Drivers on the Windows PC  so that when you do connect the Samsung Galaxy Note 3 smartphone to the computer with the USB cable the flashing tool can detect your device and then allow for the flashing.
