I have a Samsung D5500 blu ray 3D player, which i have made region free by using the procedure mentioned in the site for other post. Now i have purchased a blu ray 3D cd thru Amazon which is marked as a region code as "A" and now i can't play the CD in my player. I even tried by changing the region code to 1 which is US region code. But still it did not work. Is there solution available?
