Version 0.4.1 was the final stable release before the developer announced the tool’s discontinuation. It is widely considered the most polished and bug-free iteration. Key improvements over earlier versions include:
However, users should be aware that Samsung has occasionally changed their FUS server protocols. As a result, v0.4.1 may fail to download very recent firmware (2023 onwards) for some newer devices (S22, S23, Z Fold/Flip series). For those, the successor tool Frija is recommended.
Many users search for this exact version because:
The tool displays the binary nature (e.g., BINARY/NON-BINARY) and the bootloader version, crucial for preventing downgrade errors during flashing.
SamFirm v0.4.1 can download “Factory Binary” firmware by selecting BINARY/NON-BINARY -> BINARY/1 in the dropdown. This is useful for reviving hard-bricked devices via combination firmware.
