We recommend everyone to use Samsung’s own utilities, Samsung KIES and OTA (Over-the-Air), to upgrade their device(s) to newer software. Use SamMobile’s Firmware Portal if you are 100% sure about the risks involved in flashing your device, if flashed improperly.


SamMobile is not responsible if you brick or damage your device by using the files available on this Firmware Portal. You are doing all at your own risk! Proceed only if you are 100% sure that you know what you are doing. Again, we will not be held responsible for any device bricks or damages.


To proceed, simply select your Samsung device and country from the list fields below or enter the model number of your device in the search box above and a list of latest firmwares will come up.


If you have any questions or issues, please don’t hesitate to contact us through our support forums.
