1. Download the device 's firmware from samfw.com.
(Know your phone's model number and bit version. Do note, on that website you get the option of downloading the file from 3 sources, prefer the "from samfw.com server" option. If you have good internet speed, you may choose any of the 3.)
2. Download Samsung USB drivers. (Google it and you will know what to do next)
3. Download and install odin. Latest one.
4. Now flash the firmware by going into download mode of your device.
(Check a youtube video of how to flash firmware using odin!)
Thanks for the steps but I think these steps are not the official way from samsung. Please correct me if wrong. Needed official way to perform firmware flashing via PC.
