What is Odin 3 and How to Use to Flash Stock Firmware on Samsung

Odin is a firmware flashing tool for all Samsung Galaxy devices including the Galaxy Note 20 Ultra, Note10+, Note9, Note 8, S22, S21 Ultra, S20 S10+, S9 Plus, S8+, S7 Edge Plus, S6, S5, S4, and Tab S series. As a matter of fact, Samsung releases the official updates over the air (OTA) however there are certain cases where a Galaxy user is forced to use this tool to manually flash the stock firmware update. Like if you have boot loop issues or firmware upgrade encountered an issue error or want to downgrade firmware then definitely you need to use this flashing tool.

Samsung firmware is available online for most devices and users can easily download it for specific models, and you can use Odin to flash them onto your device.

When installing a new or older firmware version using Odin3, just make sure you’re using the same binary that is already installed on your phone. You can find your current binary version from Android Recovery mode or from Settings > About phone > Software information. For example, MMB29K.J710FXXS3AQG1, (It is from J7 recovery mode) the binary version is U3. I have highlighted the binary version in red color.


Before you start using the Samsung flash tool you’ll need the following:

  1. Samsung Galaxy device.
  2. Samsung stock firmware. You download it from Sammobile firmware directory.
  3. Download Odin
  4. Download and install Samsung USB drivers.
  5. Go to Settings > Developers options and enable USB Debugging.
  6. Back up your existing data stored on the device.
