Aimed at France (NRJ), this method allows you to use Samsung’s KIES if you don’t like performing upgrade tutorials such as ours. If, however, you go for the KIES method, you need to have stock ROM running on your device. Our tutorial isn’t asking for this ROM.

The handset you’ll install the new firmware on must be the Galaxy S3 Mini I8190N.
