How do you unlock the Samsung DVD - P191 from all regions?

The following solution was posted on Whirpool.

Turn on the unit with no disc in the unit. The No Disc message should be visible
Press the following keys in this sequence
Repeat (not the A-B Repeat, just the plain Repeat)
Fast rewind button (just below the Disc Menu button)
Play button
Down button
Down button
Right Button

The number 9 should now appear towards the left of the screen.

Open then close the disc draw

Turn off the unit and then on again. You should now be able to play DVDs from any region

Samsung dvd p191 change region to region free

turn on dvd
with no disc in tray press repeat (not repeat a-b)
press fast forward
press fast rewind
press fast forward
press up
press down

9 should appear in top left corner.

The different hacks might have something to do with the different regions the players are for. And this has anything to do with the grid you get whet you push with no disc in the tray:

Repeat
Fast rewind
Next chapter
Fast forward
Previous chapter
Play

Do not change anything! But please post what digits are highlighted in a region free player.

Yup that's it .
