Step 7: Post-Flash (If Auto Reboot was unchecked)
Hold Power + Volume Down for 10 seconds to exit Download Mode, then immediately press Power + Volume Up + Home/Bixby to boot into custom recovery (e.g., TWRP) before the system overwrites it with stock recovery.
Final Verdict
Odin3 v3.13.1-3b-patched is an essential tool in any Samsung modder's USB drive. It does exactly what it promises: removes artificial barriers that official Odin enforces. However, it is not a universal solution for all Samsung devices. If you have a Galaxy S10, Note 9, or Tab S6 – this is the best version to use. For anything newer, look for a v3.14 patched build.
Recommendation: Keep this file archived, but always check your device’s bootloader version and Android release before using it. With great power comes great responsibility – and the occasional hard brick.
Best for: Samsung devices launched between 2017 and early 2021.
Avoid if: You own a flagship from late 2021 onward, or you're uncomfortable with the risk of bypassing safety checks.
Odin3 v3.13.1_3B Patched is a specialized, community-modified version of Samsung’s official flashing utility. It is primarily designed for enthusiasts and power users who need to bypass strict factory restrictions when installing firmware on Samsung Galaxy devices. Key Features & Improvements
Bypasses Model Mismatch Errors: The standout feature of the "3B Patched" version is its ability to ignore model number checks. This allows users to flash firmware across different variants, such as switching from carrier-branded (U) to unlocked (U1) ROMs on US models.
SHA256 Integrity Bypass: It ignores SHA256 checksum failures that often block flashing on newer Samsung devices with more restrictive security protocols.
LZ4 Compression Support: This version natively supports LZ4-compressed firmware files, which became standard starting with Android Oreo (8.0/8.1).
Carrier Halt Removal: It removes certain check methods that cause flashing to halt during carrier-specific transitions. Performance & Use Cases
Reviewers and technical guides highlight its effectiveness for specific tasks:
Cross-Carrier Flashing: Confirmed to work for converting Verizon Samsung S8 (G950U) to unlocked (G950U1) and similar transitions for the S9+. odin3-v3.13.1-3b-patched
Unbricking & Recovery: It remains a reliable tool for unbricking devices that refuse standard firmware due to minor model or region discrepancies.
Modern Compatibility: While newer versions like v3.14.1 exist, v3.13.1_3B is often cited as a "sweet spot" for stability when working with Android 8 and 9 devices. Critical Risks & Cautions
Risk of Bricking: Because this tool removes safety checks (like model verification), the risk of "hard-bricking" a device by flashing incompatible software is significantly higher than with the standard version.
Security Warnings: Users should be wary of unofficial download links. Some versions found online have been flagged by security tools for suspicious strings or anti-VM tricks. It is highly recommended to source files from reputable communities like XDA Developers.
Driver Requirements: For the tool to function, the latest Samsung USB Drivers must be installed on the host PC.

Understanding Odin3 v3.13.1 3B Patched: The Tool for Samsung Power Users
If you have ever ventured into the world of Android customization—specifically for Samsung devices—you have likely encountered
. While the standard version of Odin is a proprietary internal tool used by Samsung technicians, the v3.13.1 3B Patched Odin3 v3
version (often credited to developer RealJohnGalt) has become a staple for enthusiasts. What is the "3B Patched" Version?
The "3B" or "Patched" designation refers to a modified version of the original Odin software. Samsung's official Odin often includes strict checks that prevent users from flashing firmware that doesn't perfectly match the device's original regional or carrier specifications. v3.13.1 3B Patched
version bypasses these "SHA256" signature checks. This allows users to: Switch Carriers
: Flash unbranded (U1) firmware onto a carrier-branded (U) device to remove bloatware. Cross-Region Flashing
: Install firmware from different regions (CSC) to get faster Android updates. Ignore Model Mismatches
: Overcome "Model Discrepancy" errors that often stop a flash in its tracks on standard Odin. Key Features of v3.13.1
This specific version was a milestone because it introduced support for the LZ4 compression format Modern Device Support : Samsung started using
files for firmware starting with the Galaxy S8/S9 and Note 9 era. Older versions of Odin cannot decompress these files, leading to immediate failures. Stable Interface
: It maintains the classic five-slot interface (BL, AP, CP, CSC, and USERDATA) that simplifies the flashing process. How to Use Odin3 v3.13.1 3B Patched
Using this tool requires precision, as flashing incorrect firmware can "brick" your device. Prepare the Files Final Verdict Odin3 v3

Partial Support (Some features limited)
- Samsung Z Fold / Flip series (Gen 1-2): Can flash stock firmware but cannot bypass bootloader unlock requirements unless the device is already unlocked.
- US Snapdragon Samsung devices (e.g., SM-G960U, SM-N975U): The patched version cannot bypass the CROM lock. You still need a paid unlocking service or leaked combination firmware.
C. The ".MD5" Issue
Official v3.13.1 sometimes struggles with .tar.md5 files generated by tools like Frija or SamFirm. The "patched" variant typically ensures that the internal MD5 hash verification does not cause the flash process to abort prematurely on large files (a common issue with the official v3.13.1 when flashing the AP file for the S10/S20).
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.
