People can become the root user on the Samsung Galaxy S4 SCH-R970 smartphone when they have it running on the Android 5.0.1 Lollipop updates by flashing Chainfire’s one-click rooting tool, namely CF-Auto-Root using the Odin flashing tool from a Windows computer. Chainfire’s rooting tool installs and enables the SuperSU so that people can install the applications that require root permissions before they can run.
- Users must have a computer that is running Microsoft’s Windows before they can follow this guide to flash the rooting tool on the Samsung Galaxy S4 smartphone. We are using the Odin flashing tool and it does not run unless it knows it is running on Windows operating systems. The one way around that problem if people need it would be to run a virtual machine on a Mac OS X or Linux computer.
- Users must have a Samsung Galaxy S4 smartphone that comes with the SCH-R970 before they can use this guide. The CF-Auto-Root tool that is made by Chainfire almost always arrives in a new version for each model number of the Samsung Galaxy S4 smartphone and flashing the wrong one can brick the device. Anyone suffering from a bricked device can fix it by flashing the stock ROM and trying again, but there is no use flashing the incorrect rooting file because it will not root the smartphone anyhow.
- Install the Samsung USB Drivers on the Windows computer  before beginning so that the Samsung Galaxy S4 smartphone can be detected by the Odin flashing application once we attempt to connect.
BEFORE WE BEGIN
- Note that Chainfire was running on the LRX22C.R970TYUGOH2 firmware build number when he created the one-click rooting tool for the Samsung Galaxy S4 SCH-R970 that is available in this guide, but that does not mean people need to be running the same. There are often heaps of firmware build numbers that are based on Android 5.0.1 Lollipop depending on where people are in the world. The rooting file should root the Samsung Galaxy S4 SCH-R970 no matter the firmware builds number provided that it is running on the Android 5.0.1 Lollipop software updates.
- If the Samsung Galaxy S4 smartphone does not have the Developer Options menu available from the Settings menu then people need to unlock it by tapping on the Menu > Settings > About Device > Build Number. Keep tapping a finger on the build number until it says that people are using the device as a developer now–that is when users know that they have unlocked the Developer Options menu.
- Enter the Developer Options menu on the Samsung Galaxy S4 smartphone with the SCH-R970 model number by tapping on the Menu > Settings > Developer Options and then check the box that is available for the USB Debugging. Once the USB Debugging Mode has been turned on, leave the Developer Options menu, and the Android operating system remembers that settings automatically.
