ON DVD without disk;
Points the remote control at the device and types 31415900 "EXIT";
It is going to a message appear in English and there your device is ready for any region.
To use in all regions use this code:
31415900 and press exit
IN stand-by mode you press in the remote control:
0 0 1 for region 1
0 0 2 for region 2
0 0 3 for region 3.....etc.
When there is no disc in the player, press "0" "0" and then "exit". This will set it to all regions.
For any time you want to change regions and have already entered a hack code, hit the "power" button which puts it into standby mode, and then "power" again to bring it out of standby mode.
With no disk in it, press "0" "0" "" for the region you want. and then "exit" and it will set it to this region.
This is similar to the D-12 hack EXCEPT the D-10 doesn't have a clear button. The other hack mentioned here is with a long number string and then "exit" so I figured out to try "exit" with the D-12 hack code.
