After everything is in order with your phone and your laptop, download, on the latter, Odin from here and the new XXAMJ3 official firmware.

  1. Once they are saved there, too, start the first step of our guide with these instructions: extract the two files, boot the phone in Download Mode and then connect the Galaxy S3 Mini I8190 to the laptop; to successfully enter Download Mode, you should perform these guidelines: pres + hold, at the same time, Volume Down, Home and Power till Android’s icon is displayed, then, when you see it, make sure to press only Power. And you’re now done with the booting into Download Mode.
  2. Move on to this step: make sure the devices are connected to each other by looking for a message saying “Added!!” and an ID:COM box which should be all yellow; if they’re nowhere to be seen, there was a problem and you have to try a different approach. What you should do is this: either flash the USB drivers again or look for another USB port to use.
  3. Now on to the next task, which is the following: look for PDA, click on it, choose a file with CODE in the name, search for Phone, tap this one too and then choose a file with MODEM in the name, click on CSC and select a CSC file, then tap PIT and choose a file which should have .pit as its extension.

  5. Once you do the latter, the flashing of the Android 4.1.2 XXAMJ3 stock firmware will commence, so wait until it’s over. You will then be shown a “Pass” message.
  6. After your handset restarts, you will be required to do this: unplug the smartphone from your laptop or PC.

You are now able to use your Galaxy S3 Mini I8190 in all its upgraded, and thus wonderful, splendor!
