This tricks only works if your DVD is in Zone 2.

• Empty the DVD tray
• Power off / Power On
• Wait for the boot
• Press 5 times 0 within 1 second
• Press “Repeat”
• Type: 57538
• You should see a “2″ in the upper left corner of the screen
• Quickly type 9

That’s it.

(Apparently if your DVD is Zone-2 then you should type 76884 instaed of 57538, but I couldn’t confirm it)
