How to Flash Firmware on Samsung Devices [Step-by-Step Guide]

Flashing firmware is a powerful method to fix software issues, update Android, or unbrick your Samsung phone. In this post, we’ll walk you through the safe way to flash firmware using Odin.

⚠️ Disclaimer: Flashing firmware may void your warranty. Please proceed at your own risk and always back up your data.

What You'll Need:

• A Windows PC or Laptop
• Samsung USB Cable
• Samsung USB Drivers
• Odin Tool (Latest Version)
• Correct Firmware for Your Model (e.g., from Samfw, Frija, or Gsmdevelopers)

Step-by-Step Firmware Flashing Process:

1. Install Samsung USB Drivers

Download and install the drivers so your PC can detect your Samsung device properly.

2. Download Odin Tool

Extract the Odin ZIP file and open Odin3.exe.

3. Boot Your Samsung into Download Mode

Turn off your phone, then press and hold Volume Down + Power + Home (or Bixby) button together. Then press Volume Up to enter Download Mode.

4. Connect Phone to PC

Odin should detect your device and show "Added!" in the log box.

5. Load Firmware Files into Odin

Click each button and load matching files:

• BL = Bootloader
• AP = System (may take time to load)
• CP = Modem/Radio
• CSC = Country/Region settings (Use HOME_CSC to keep data)

6. Start Flashing

Make sure “Auto Reboot” and “F. Reset Time” are checked. Then click Start.

Wait until you see PASS! in Odin and your phone restarts. That’s it!
