The Smart Switch can recover your soft-bricked device or look for OTA updates in your region. If these are the only two things you want to do, you may use the first method.

The 2nd method is to flash the firmware through Odin. This method is for pro users, but if you just follow the instructions to the letter, you can use it being an average user too. The Odin method is also known as manual firmware installation. In this case, you will download the firmware files of your choice and then flash them. This method is useful to completely wipe the previous firmware and install a new one over it. It will let you flash a new software updating without waiting for it in your region. It will also unroot the phone and restore everything back to factory settings.
