Switch machine on without disc
Press setup
Then press buttons in following order on remote
NEXT - STOP - PAUSE - PREV - NEXT
This will take you to the loopholes menu
From here you can pick the which region you want or pick bypass to make region free but not RCE free. You have to select region 1 if you want to play RCE encoded discs. Sorry no macrovison disable available via this menu.
Hope this will help you
