Getting access to the root file system on the Samsung Galaxy S4 SGH-M919N smartphone is the only way to start installing the best applications. These apps aren’t just for fun either. You can install the Tasker app which is like having total automation on your device. Think of it like your own robot personal assistant that looks after your device and not just says things like a Siri would. In fact, it’s probably ten times more powerful than Apple’s Siri and Cortana combined. These are the kind of experiences you can have when you root the Samsung Galaxy S4 device. Another thing that most Samsung device owners love is the Triangle Away app made by Chainfire. With the triangle Away application, you can take off the yellow warning triangle that is displayed if you are running custom firmware. A must have app for most Samsung owners.

Rooting the Samsung Galaxy S4 (SGH-M919N)

  1. Download the rooting bundle from the first link directly to your Windows PC.
  2. By default, that rooting zip file will end up in your folder called Downloads.
  3. Open the Downloads folder and transfer the zip file over to the desktop. Just click and drag the file.
  4. Once on the desktop, right-click the mouse on the file and click the “extract here” option from the menu.
  5. You now have all the executable files on the desktop from inside the zip file. Double-click the Odin file and it will run on your computer. Leave the Odin user-interface open and proceed.
  6. Turn off your Galaxy S4 device and reboot it in download mode. To enter the download mode, reboot by holding the Power + Home + Volume Down buttons simultaneously.
  7. Connect the Galaxy S4 to the computer using the USB cable.
  8. Wait for the Odin user-interface to change the color of the ID: COM port. When the color changes, you know the driver is working. If the ADB driver isn’t working, download the Samsung USB driver and try again.
  9. Here is your troubleshooting point. If you see the ID: COM port light, you know every problem from this point forward is not driver related. If the flashing doesn’t work and your light does work, try installing a different Odin version and trying again. Those without a light know they must get the drivers working.

  11. Browse the desktop for the CF-Root file.
  12. Click the Start button from the Odin user-interface.
