No source code – You can’t verify what was patched. The original Odin is closed source; patched versions are reverse-engineered.
Due to the legal restrictions surrounding modified Samsung tools, you will not find this on the official Samsung website. You must source odin3v31313bpatched zip from reputable development forums (XDA Developers, Samloader, or known Git repositories).
Always verify the file hash. A clean, unmodified version of this file should have the following SHA-256 checksum (example - check with your source): (Note: Specific hashes change per compiler; always verify with the developer's thread.)
Do not download from random file-sharing sites. Many fake versions contain generic malware. The true "better" version is clean, open-source patched, and under 2MB compressed.
Odin3 v3.13.1 3B Patched is a specialized version of Samsung's internal firmware flashing tool. It is widely used by the Android community to bypass specific security checks that the standard version enforces, such as preventing the installation of firmware from different regions or modified images. Key Features of the Patched Version LZ4 Compression Support : Version 3.13.1 was the first to support the
compression format used in Samsung firmware starting with Android 8.0 (Oreo). Bypassing Model Mismatch
: The "3B Patched" modification specifically allows users to flash firmware that might otherwise be blocked due to model name mismatches (e.g., flashing a different region's software). Custom Binary Compatibility : It is often required for flashing custom recoveries like
or modified kernels that the official Odin tool might reject. Repair Wiki How to Use Odin3 v3.13.1 3B Patched

Odin3 v3.13.1 Patched (often referred to as "Odin Patched" or "Odin 3B Patched") is a modified version of Samsung's proprietary firmware flashing tool. It is specifically designed to bypass the SHA-256 integrity check that standard versions of Odin enforce. Why use the "Patched" version? While official Odin versions like
are standard for official updates, the patched version is essential for: Cross-Region Flashing:
Installing firmware from a different region (CSC) that the standard tool might block. Custom Binaries:
Flashing modified or unofficial firmware without triggering common validation errors. Downgrading:
In some specific cases, it helps bypass version checks that prevent moving to older firmware. Core Flashing Components
When you unzip the firmware and Odin files, you will typically see these slots in the interface: BL (Bootloader): Contains the bootloader files (prefix AP (System): The largest file (prefix ), containing the actual Android OS and system partition. CP (Modem): Handles cellular and radio communications (prefix CSC (Region):
*: Use this for a clean install; it will factory reset your device.
*: Use this if you want to keep your data and apps while updating. Safety Tips for Samsung Flashing Ensure you have the Official Samsung USB Drivers installed so your PC recognizes the device in Download Mode Cable Integrity:
Use a high-quality USB cable. If the connection drops during a flash, it can "brick" your device (make it unbootable). Ensure your phone has at least 50% battery to prevent it from shutting down mid-process. Verification:
Always double-check that your phone model (e.g., SM-G991B) exactly matches the firmware you downloaded. For reliable firmware downloads, sites like are commonly used by the community. step-by-step guide on how to put your particular Samsung model into Download Mode
The Odin3 v3.13.1 3B Patched version is widely considered "better" than standard versions because it bypasses specific Samsung security checks, such as Model Number mismatches and SHA256 verification errors. These patches allow users to flash cross-carrier firmware or modified files that the official, unpatched tool would normally block. Key Advantages of the Patched Version | Need | Safer Alternative | |------|-------------------| |
Bypasses Model Mismatch: Standard Odin often blocks firmware if the model number (e.g., SM-G960U vs. SM-G960U1) does not match exactly. The patched version ignores these checks, enabling carrier switching (de-bloating) or flashing unlocked firmware onto carrier-locked hardware.
SHA256 Fix: Fixes "SHA256 is invalid" errors that frequently occur when flashing certain official or modified firmware packages on newer Samsung devices.
LZ4 Support: This specific v3.13.1 version was the first to support LZ4 compression, which is required for Samsung firmware released with Android 8.0 Oreo and newer.
Improved Device Compatibility: Includes patches specifically designed to improve reliability for the Samsung Galaxy S7 series and newer models. Core Functionality
Like standard versions, this tool is used for several critical firmware tasks:
Unbricking: Repairing devices stuck in boot loops or on the Samsung logo.
Firmware Updates/Downgrades: Manually installing the latest security patches or moving to an older OS version.
Flashing Custom Files: Installing custom recovery images (like TWRP) or root packages. Basic Flashing Steps
When using this tool, you typically load files into these specific slots:

When flashing firmware on Samsung devices, Odin3 v3.13.1 Patched (often found as a Brick your device
file) is generally considered "better" than the standard version for specific custom tasks. Why the Patched Version is Better Bypasses Checksum Errors
: The patched version, often referred to as the "3B Patched" or "PrinceComsy" version, ignores model-specific checksums. This allows you to flash firmware that might otherwise be rejected by the standard Odin tool, such as cross-region firmware or modified files. Fixes "Stuck" Issues : Upgrading to at least version
is the recommended "proper piece" of software to solve issues where Odin gets stuck on specific files like metadata/fota.zip Supports Newer Compression
: Version 3.13.1 and newer are required for newer Samsung devices that use the
file compression format, which older versions of Odin (like 3.10.7) cannot process. Key Usage Tips CSC vs. HOME_CSC : If you want to keep your data, use the
file. If you want a clean factory reset to fix deep system issues, use the Run as Admin : Always right-click the Odin executable and select Run as Administrator
to ensure it has the necessary permissions to communicate with your device. USB Connection : Use a high-quality USB cable and, if possible, a USB 2.0 port
on your computer, as USB 3.0 ports can sometimes cause "SetupConnection" errors. (BL, AP, CP, CSC) into Odin?
Odin3 is a tool developed by Samsung for its service personnel to flash firmware, kernels, and other data to Samsung devices. It's a Windows-based application and has been widely used by both Samsung service centers and end-users to install official firmware and other software components.
You have a Samsung device stuck in a "Qualcomm Crashdump" or "Yellow Triangle" loop. Stock Odin fails at sboot.bin due to corrupted headers. The patched version uses a relaxed hash check, often forcing the write where stock tools give up.
