Odin3-v3.13.1-3b-patched May 2026
Here’s an interesting write-up on Odin3 v3.13.1 (3B patched) — a tool well-known in Samsung firmware modding circles.
Step 4: Load Firmware Files
In the patched version, you can load tar.md5, .img, or even raw .bin files. The typical slots: odin3-v3.13.1-3b-patched
- BL: Bootloader (aboot.mbn, sbl1.mbn)
- AP: System, kernel, recovery (largest file)
- CP: Modem/radio firmware
- CSC: Country-specific settings (CSC_HOME preserves data)
- USERDATA: Optional – for OEM-specific bloatware.
Pros 👍
- Bypasses Stock Restrictions: The main reason to use it. If official Odin throws a
SHA256 is invaliderror, this patched version often sails right through. - Rock-Solid Stability: Despite being a mod, crashes are extremely rare. It maintains the core stability of v3.13.1.
- Clean Interface: No extra bloat or confusing checkboxes. It looks identical to official Odin, which is a good thing.
- USB Performance: Excellent reconnect speed after a device reboots into Download Mode – critical for multi-step flashing (BL, AP, CP, CSC).
- Wide Device Support: Works perfectly on Snapdragon variants (where bootloader unlocking is possible) and all Exynos models from the S7/S8 up to the S20/Note 20 series.
2. RMM State (Remote Mobile Management)
Introduced around 2018, RMM locks the bootloader for 7 days after a factory reset. During this period, OEM Unlock is hidden. Stock Odin respects this lock and blocks flashing. The patched version ignores the RMM flag entirely. Here’s an interesting write-up on Odin3 v3
Not Supported
- Devices on Android 12 / 13 with bootloader v5+ (e.g., Galaxy S21, S22, S23 series). These require Odin v3.14.x with official signed binaries only.
