Many apps require making these changes, and there are other things like custom ROMs that improves the appearance and features of your operating system. Rooting the Android operating system running on the Galaxy Express smartphone means being able to customize the device in thousands of different ways.

REQUIREMENTS

  • Chainfire had created the CF-Auto-Root tool for the Galaxy Express 2 SM-G3815 when he was running the KOT49H.G3815XXUCNH1 firmware build number. That does not mean you need to be running that same firmware build number on your device. Chainfire just shares the firmware build number he was running because he says that some Samsung devices do not boot old images.
  • You must have a Windows operating system running on the computer that you are using the guide for the Odin flashing application to work. The Samsung developers made the Odin flashing application to work on Windows PCs only.

BEFORE WE BEGIN

  • You need to unlock the Developer Options menu on the Samsung Galaxy Express 2 smartphone before you can use this guide because you need to turn on the USB Debugging. You can unlock it by tapping on the Menu > Settings > About Device > Build Number. Continually tap on the build number until the Android OS gives you a message on the display that says you are using the device as a developer and then continue with the next step.
  • Now it is time to enable the USB Debugging Mode from the Developer Options menu on the Galaxy Express 2 smartphone. We do that by heading back to the home screen and then tapping on the Menu > Settings > Developer Options > USB Debugging. Once you have checked the mark so that it is no longer empty, leave the Developer Options menu, and the Android software remembers your preferences.
  • Install the Samsung USB Drivers on the computer before you begin so that they can help your smartphone be detected by the flashing application we are using to root the device.
