If you own a Samsung Galaxy device and want to install a custom ROM, you’ve probably stumbled upon Samsung Odin. Flashing ROM on your smartphone device is a delicate task.

You should come prepared!

Below you will find out what exactly Samsung Odin is, how to complete the Samsung Odin download, how it works, how to use it, and most importantly, what to do if something goes wrong.

Part 1. What Is Samsung Odin

Samsung Odin is a firmware flashing software. It’s developed for Windows users exclusively. It has two main functions – it’s a diagnostic and ROM flashing tool for Samsung Galaxy devices (smartphones and tablets). While the software was developed by Samsung to be used only internally, it leaked, and users can now access it for free.

The suite allows you to update ROM on your Samsung device. You can use the official Stock recovery firmware or download a custom one. The app allows you to custom-tailor your Android experience. Here is what it can do:

  • Flash stock or custom firmware – update your phone with custom firmware or use the stock one to fix common problems such as bootloop, software bugs, or app crashes;
  • Flash recovery file – you don’t need to flash the entire firmware. If you only want to flash the custom recovery file, you can do it with this tool;
  • Flash root package – you will be able to flash custom root packages;
  • Flash kernels – tweak the performance of your device by flashing a custom kernel of your choice.
