Samsung Gear S2 Sm-r720 Firmware Download [exclusive] Site

This guide covers the differences between software versions (Tizen vs. Wear OS), how to identify the correct files, the risks involved, and a detailed walkthrough of the installation process.

Benefits of the latest firmware:

• Improved battery life (especially for watches 5+ years old).
• Fixed Bluetooth dropout issues with Android 11 and 12 phones.
• Security patches up to 2021 (Samsung no longer supports the Gear S2 with new updates).

Step 4: Load the Firmware Files

• Click the “BL” button and select the file starting with BL_.
• Click the “AP” button and select the AP_ file. (This will take 10–20 seconds to load because it is large).
• Click the “CSC” button and select the CSC_ file. Do not use the HOME_CSC version unless you want to keep user data (but for a clean flash, use the standard CSC to wipe everything).
• Leave “CP” blank unless your firmware includes a modem file.

Important notes before you begin

• Only use firmware specifically for SM‑R720. Flashing incorrect firmware can brick your watch.
• Official firmware is preferable — it preserves warranty and stability. Custom ROMs are rare for Tizen watches and riskier.
• Back up any important watch data where possible (paired phone data, health logs may sync with Samsung account).
• Ensure battery is at least 50% (preferably >70%) before updating or flashing.

Step 5: Configure Odin Options

On the left side of Odin, ensure only these boxes are checked:

• Auto Reboot
• F. Reset Time
• Do NOT check “Re-Partition” or “Nand Erase”.

Hardware:

• A Windows PC (Windows 7, 8, 10, or 11).
• The original magnetic charging cradle for the Gear S2 (DO NOT use a third-party dock for flashing; power interruptions are fatal).
• A reliable USB data cable (for the cradle).

4. Required Tools

• Odin3 (v3.14+ recommended) – Flashing tool for Samsung devices.
• Samsung USB Driver – Ensures proper PC–watch communication.
• Gear S2 USB dock – Required for wired connection (no wireless flashing).
• Windows PC – Odin is Windows-native.

Identifying Your Exact Model: The SM-R720

It is vital to distinguish the SM-R720 from its siblings. The Gear S2 family includes:

• SM-R720: Standard Bluetooth/Wi-Fi model (No 3G/LTE). This is the focus of our article.
• SM-R730: 3G model with a SIM card slot.
• SM-R732: Classic edition with a leather band and a different bezel design (mostly similar firmware but not interchangeable).

Warning: Flashing firmware intended for the SM-R732 or SM-R730 onto your SM-R720 will permanently brick the device. Always double-check your model number in the watch’s "About" section or on the back of the watch case.
