Hello!

I've tried to unlock my region 2 HT-X30, and make it region free (or, at least, region 1). I've used 8, 4, 2, 6, 9, my played turned off. Now I'm not able to play Region 2 DVDs ("Unkown disc"), and when I try to play region 1 DVD, it starts playing, but:

- first, I see thousands squares on my screen (like that http://pichdwallpaper.com/wp-content/uploads/2014/12/colorful_squares.jpg, but hear the background music (I think it's a trailer of a movie, of something like that). Then menu shows up, and I'm able to choose between "Play movie", and "Choose scenes" options, but when I "click" on one of them, nothing happens. Help! .
