Hi there, i'm a newbie to this site so please bear with me.... I've found another way to unlock the region code, and it requires no download or disc burning.
Firstly have your tv on and set so you can view the dvd player and be sure not to have a disk in there already.
Switch off the machine with the button on the machine.... NOT THE REMOTE.... And then unplug from the wall.
Wait long enough for the power led light to go out, 10 seconds or so.
Plug the machine back into the mains power supply and turn on the machine with the button on the machine...NOT THE REMOTE..
When powered up open the disk tray and then press 0 0 0 0 on the remote (zero 4 times) and you should get a menu on screen. Press 0 until the numbers are changed and then shut down the machine and then turn back on. Presto you should have a region free player.
Hope this helps as i spent 4 hrs trying the download way and all it took was the pressing of a few buttons
