Wow, who would have thought - Multi Region Samsung

I've found this hack somewhere on the internet, it works for my R2 player. 

1) Turn on the player with no disc in the tray 
2) Press the Open/Close button to open the tray 
3) Press the info button, the firmware version shows up (mine was 080220.13.B.1080PXKEG) 
4) After the version info disappears, close the tray again by pressing the Open/Close button 
5) At this point, it will show "no disc" at the top. Press the Info button again, and this will disappear. 
6) Now type the code that applies for your region (R2 is 57538). A '2' will briefly show up at the top left corner 
7) Now press 9, and 9 will show up in the top left corner 
8) Power off the player, and turn it on again. You'll have a multi region player 

I've found the following codes at the 1080P7 hack: 
R1 - 29334 
R2 - 57538 
R3 - 56732 
R4 - 76884 
R5 - 53814 
R6 - 24462 

Not sure if all are correct, but it worked for R2.
