Greetings, I have been trying to find a hack for my Sanyo DWM-450 for several months now to make it region free. I have scoured the internets for a long time without any luck. I have tried several options that i stumbled upon and none of them worked. I read somewhere that i need a firmware patch to make the DVD player region free. Can someone help me out? The most common solution that i have come across is mentioned below and this does not work. Sanyo DWM-450 - Not Working Hack 1. Power on the DVD player. 2. Eject the DVD tray by using remote controller. 3. Press 5, 7, 9, 2 in sequence. 4. Select 0 to set the DVD player to multiregion. 5. Close the tray.
