- Use this tutorial only with the variant of Samsung Galaxy S4 model number M919. Don’t try to use this tutorial with any other Android device.
- The computer that you’re about to use should have the Samsung USB drivers installed on it. Download link here.
- The tutorial doesn’t contain any Factory Reset steps, but you should still backup some of your most important data. If the phone doesn’t want to boot after root is applied, then you will be forced to boot into Recovery mode and apply Factory Reset process yourself.
- For this guide to be completed successfully you need to know how to boot into Download Mode and use Odin program to flash the required files.
- Enable USB debugging option from the Android’s Developer Options menu. If this section doesn’t show up in Settings, then you should open About Phone menu and then tap 7 times on the Build Number area, the Developer Options will appear now.
- Disable the Samsung KIES software from running on your PC, as this might interfere with the rooting process.
- Disable all running Anti-virus applications.
- Make sure that the phone’s battery has enough power left before it completely drains. If the phone powers off in the middle of the rooting process, then you will be forced to repeat the entire tutorial.
