Mahmoud Salah - Samfirm Tool V1.3.1 By

Samfirm Tool V1.3.1 (by Mahmoud Salah) is a Windows utility used to download official Samsung firmware files by querying Samsung servers with model and region identifiers. It streamlines locating and retrieving stock ROM packages for device repair, flashing, or testing.

Cause: The Model/Region combination does not exist, or Samsung changed the API endpoint. Fix: Update the SamFirmData.dll file. Search XDA for the latest .dll replacement. Alternatively, try a different region (e.g., "EUX" for Europe multi-CSC).

Note: For Samsung devices released after 2022 (especially those with Android 13+), Samfirm V1.3.1 may have difficulty fetching firmware due to changes in Samsung’s server encryption. For older flagship devices (S9, Note 9, S10, S20, A-series up to 2021), it works flawlessly.
