Lg dv340 how to unlock regional codes for all codes

I think you can unlock regions but it might require you resetting the region your player is registered in. This may be of help to you -

shuold do it

Doesn't work. Press 0 four times did absolutely nothing.

Hack sites for freeing region say that there is no hack code.

Ok so here is how it was done.

Press the Pause button on your remote control. Using your remote control enter the code 3, 1, 4, 1, 5 and 9, Press the 0 button on your remote control for Region free, 1 for Region 1 or 2 for Region 2. Press the Pause button on your remote control. Power off your player and wait a few seconds. Power on your player
Or
Press the Setup button on your remote control then, Step, Next, Up and Down, select the region of your choice or Bypass for region free, save and then Exit the menu.

it depends on what region your player is, most likely you need to unlock your region code(if there is an available unlock for your player) if you want to play that disk. but it simply means your dvd and your player is not on the same region

Try one of these:

1) Press 'setup' on remote control
2) Move down to the 'lock' picture
3) Press '0000000'
4) Select region code as '0'

Or

1) Power on player with no disc in tray
2) Press PAUSE
3) Key in 314159
5) For multi-region, select 0
6) Press PAUSE again
7) Power off player
8) Wait a minute turn it on.

YES, it can be changed to view all regions. I've just done my new RC388 (bought it 4 hours ago) and it works.

To start the hack:
Click the home button on the remote, go to the Setup page, highlight the 16X9 TV aspect ratio and enter in this coded sequence: 1 3 9 7 1 3 9

A new factory menu now comes up on the screen.

To change the values of these options hit the enter button and scroll with arrow keys until you get to the option you want to change. For the region code hack replace the value of "option 5" with the value of: ff

Press enter.

(Changing this value will set unit to region code 0 which should allow any region to be played on the player.)

Now, hit the "return" button to save and exit.

Switch off the machine - switch on - all is well now.

Good Luck,
Will

power on
open disc tray
press 0 0 0 on your remote
select region 0
press pause button
press power button to switch off
leave off 30 seconds
should then play all regions

try with the disc tray closed. and if that doesn't work turn player off by plug socket and turn back on and start from the setup menu part of the unlock code after turning player back on.
