You might already be familiar with the term “Odin” if you have looked for advanced ways to customize your Samsung phone on the internet. NetOdin3 is an extension to Odin with support for flashing the firmware wirelessly. With these useful tools, you can root your device, flash stock recovery, repair Samsung devices stuck on the startup screen, unlock patterns, FRP, and more. In this guide, I’ll walk you through the steps to flash firmware wirelessly on a Samsung device using Odin. Also, I’ve added a download link to the NetOdin tool.

One question that might pop up in your mind is why do we need NetOdin if there’s Odin that can do all the jobs? Well, both the tools do the same job, Odin does not work on all Samsung phones. It requires your Samsung device to connect with the PC via a USB cable. Not all Samsung devices such as Galaxy Watch 4 have USB support. Hence, you can’t use the Odin tool on such devices. That’s when NetOdin comes into play, as it does not require a wired connection to your PC.
How to Download and Install NetOdin / NetOdin3
- Download the NetOdin zip file on your PC.
- Extract the file, and you’ll get the NetOdin3.exe file.
- Double-click on the NetOdin3.exe file to begin the installation.
- If you see an alert from Windows Security, click Allow access. Otherwise, Windows Firewall can block some of its features.
