Open Settings → About phone and confirm SM-F976W. In Software information, compare the installed build and service provider software version with the source listing.

Check the CSC and bootloader revision before choosing a package. A later release date does not by itself establish compatibility, and bootloader restrictions may prevent a downgrade.

For a routine update on a working phone, start with Settings → Software update. If you need to reinstall the software manually, back up your data first and check the installation method for the selected package.
