SAMPLE

Download Firmware with GNSF

You can download firmware files using GNSF (Get New Samsung Firmware), a tool that allows direct firmware downloads from Samsung servers.

Download GNSF Tool

GUI Version (Windows) Console Version (Windows) GNSF Tool Info

Quick Command for This Device

Replace YOUR_IMEI with your device's IMEI and XAA with your region code.

Additional Options

-v VERSION - Specify version
--resume - Resume downloads
--no-decrypt - Skip decryption

IMEI Important: You should enter your complete IMEI number. While GNSF can attempt to generate missing digits if you provide only the first 8+ digits, this may not be sufficient for downloading firmware in all cases. Using your full IMEI ensures the highest success rate.

Important Flashing Info

To Keep Your Data When Flashing:

Always use HOME_CSC file instead of regular CSC file in Odin's CSC slot!

HOME_CSC - Region config (keeps data)
