However, there are certain cases where a Galaxy user is forced to use this tool to manually flash the stock firmware update. For example, if you have bootloop issues a firmware upgrade encountered an issue error or you want to downgrade firmware then you must use this flashing tool.

Samsung firmware is available online for most devices, and users can easily download it for specific models. You can also use Odin to flash it onto your device.

When installing a new or older firmware version using Odin3, just make sure you’re using the same binary that is already installed on your phone. Your current binary version can be found in Android Recovery mode or by going to Settings > About Phone > Software Information. For example, in MMB29K.J710FXXS3AQG1, (it is from J7 recovery mode), the binary version is U3. I have highlighted the binary version in red.
