If you feel like you want to alter what you see on the Android operating system but you do not want to install a custom ROM because you feel like that is too large a risk to take, then you might be interested in substituting that idea for becoming the root user instead.
The user in Android has the master key to the OS, and it allows them to do anything they want. With mobile operating systems, that is always referring to the use of apps and getting to decide what is installed and what is uninstalled. That even includes getting rid of any of the apps that are already on your device when you buy it and the apps that you did not have a say when they were forced onto your device without any way of being able to remove them.
- You need to have the Samsung Galaxy Note 2 smartphone that comes with the SHV-E250K model number to use this guide. Any of the other model numbers are going to get bricked if you use them when flashing the rooting file in this post.
- You need to have a computer that is running on a version of the Windows operating system to use this guide because the Odin flashing tool does not run on any other operating system.
BEFORE WE BEGIN
- Chainfire had the KOT49H.E250KKTUKNF7 firmware build number on the Samsung Galaxy Note 2 SHV-E250K smartphone when the version of the CF-Auto-Root tool that he developed in this guide was created. Him running that firmware does not mean you need to be running the same. He gives that firmware information so you can use it as an indicator.
- Install the Samsung USB Drivers  on the Windows operating system before you get started with the guide so that when you connect to the computer the Odin flashing application is then able to detect the device and allow for the flashing to work.
- Unlock the Developer Options menu  on the Samsung Galaxy Note 2 SHV-E250K smartphone so you can enter it and then enable the USB Debugging Mode  from the Settings.
