Samsung Odin, often known as Odin3, is a simple and lightweight stock ROM flashing utility for the Samsung Galaxy series of devices, including smartphones and tablets. You may rapidly install new firmware or a custom recovery like TWRP (.tar) by downloading Samsung firmware or firmware binaries, selecting the relevant fields in Odin, and installing new firmware or a custom recovery like TWRP (.tar). Samsung Odin is a must-have program if you wish to manually update your Samsung device, fix a boot loop, or install a custom recovery or kernel.

Odin 3.14.4 (2021) is now available for download.

Check out our compatibility list to figure out which Odin version you should use.
Please be aware that Odin does not support Mac OS X or Linux. However, Odin alternatives such as Heimdall and JOdin3 can be used to flash the firmware.

Heimdall is a cross-platform open-source Odin replacement (Linux, Windows and Mac OSX). Heimdall interacts with a device in download mode that can flash Android ROMs or Kernels onto Samsung Galaxy S phones using the same protocol as Odin.

Heimdall is a Mac and Linux version of Odin

Odin is only available for Windows, thus Mac and Linux users will be unable to use it. Don't worry; there's an open-source utility called Heimdall that works on Linux, Mac OS X, and Windows. It's a fantastic Odin substitute, and you can get the most recent version from the official website.

For Mac OS X and Linux, there's Heimdall.

JOdin3 for Linux can be downloaded here.

For Linux users, there's a particular version of Odin called JOdin3 CASUAL, which requires Java 8 to run. Toby4213 from the xda forums deserves credit for providing the latest JOdin3.

Tips: Extract the jodin.gz file to the desired directory: /home/username/programs/jodin/ (for example). Then right-click on the JOdin3CASUAL file. Make sure you already have Java version 8 or higher installed.
