Trust the guys over at Sammobile to have you covered when it comes to firmware, both official and leaked, for every Android device made by Samsung, and they have released the first set of stock firmware for the Samsung Galaxy S DUOS, following the Galaxy S3 LTE.
These firmware can be flashed on the phone using Samsung’s firmware flashing program, Odin. While most would never need them, those who intend to play around with custom ROMs and the like to get more out of their Galaxy S DUOS would do well to keep these firmware handy, as they will allow you to revert the phone to a working state if something goes wrong.
The firmware are currently available for a few countries such as Philippines, Vietnam, Hong Kong, Germany, etc and more should be released once Sammobile gets their hands on them, though you can always flash another country’s firmware on your own. Go ahead and download the firmware from the Sammobile firmware page.
