I had a Samsung media player for the US market, its functions were super limited (music, video, images, shit games) compared to the Korean market release ( previous list, better games plus two player live Bluetooth games, subway maps for major global cities, multi language dictionaries. Note taking app, ecpanded themeing of interface)

I found the firmware updater online, the Korean releasr OS version , and part of that process was just Editting the bluetooth MAC manually in a text file prior to reflashing....it was an eye opener to MAC/NIC stuff not being as locked down like all the software licensing vendors portrayed it was.
