How to install Samsung Official Firmware (Stock ROM) using Odin

Odin aka Odin Downloader is the one which can be used to flash the official firmware easily for the Samsung devices. It is used internally by Samsung to flash and test the stock firmware on their Galaxy devices even though it was never rolled out for the use of common people. But it was leaked on the internet for the public where the inputs of the firmware files are in the form of .tar or .tar.md5 formats.

Preparations By The Downloading

Just go through all the preparation steps before heading to the installation.

  •  Always have a Backup.

It’s highly recommended that you should do a complete backup of all your device data before heading to the installation.

If you are having a rooted device, then you can take Nandroid backup using TWRP or with a Titanium backup to get the complete backup of the installed apps and related data.

Samsung users can use Smart Switch to backup data on the computer. Samsung Smart Switch even allows the users to move data from one device to another of different variant (like moving data of Galaxy S7 to Galaxy S8).

  •  Install Samsung USB Drivers.

You must have a proper connection between your Samsung Galaxy device and the PC prior using the Odin Flash Tool. Also make sure that before starting Odin Flash Tool, you have completely disabled the Samsung Kies if it’s installed on your PC as it can disturb the Odin tool connection and lead to bricking of the device.
