Won't play because of region code

There are a few things about Blu-ray region codes you should know about before buying a Blu-ray player. One of them is that Blu-ray region codes mean that Blu-ray players sold in a specific region can only play Blu-ray discs that are made to be played in that region. There are in total 3 different regions, labeled A, B and C.
Region A: North America, South America, U.S. Territories, Japan, South Korea, Taiwan, and other areas of Southeast Asia
Region B: Europe, Africa, Middle East, Australia, and New Zealand.
Region C: Asia (except for Japan, Korea, Taiwan, and other areas of Southeast Asia)

You can download a region-free Blu-ray player and then you can play the region-locked discs on the player. Try Leawo Blu-ray Player which is free.

Works on the BDP 2700 -
turn on player without disc. push home button(looks like a house) on remote. enter 1389310 using remote. wait 10 sec then turn off at front of player. wait 10 sec then turn on at front of player.

I believe the 7200 is not able to be unlocked for region free play though
