Multi Region for LG DV398H

You can not. You need a multi region player or by the specific region player

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

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

I just happened to be the 385th person to look for this fix. I have some good news...Use the fix for region changing a LG DV-8600 DVD. It worked for me!
1. Power On
2. Open Tray
3. Press 0 0 0 0
4. Change the region (0 = multi-region)
5. Press PAUSE

try this; its for a different model but looks simalar and ay work.

1. Turn power on
2. Open tray
3. Press 0, 0, 0
4. Change the region (0 = multi-region)
5. Press PAUSE

1. Turn on the player (without a disc inserted)
2. Close the disc tray
3. Press MENU, 1, 9
4. Selection menu will be displayed
5. Press ENTER
6. Select region
7. Press ENTER
8. Press OPEN/CLOSE

No, sorry. Buy another DVD player for the other region, or buy a multi-region DVD player.

IF there is a code for it you will have to check on some of the sites that have region hacks for DVD players. Not all players have the capability of changing them to region free. I looked to see if your model was listed on a couple of the sites that have directions, info and or firmware updates to change region settings on various makes and models of players, and I didn't find yours listed anywhere. It may use methods from other LG models, but you have to do a little research, some google searches and a little trial and error. Keep in mind that applying these hacks can render your unit inoperable and not recoverable. You might want to look into getting an inexpensive player from Phillips, Durabrand, Apex or one of several other manufacturers that are easy to find codes for and simple to change region coding, and in alot of cases cost less than 50 USD. Phillips are the easiest to get codes for and they are reasonably priced in most department stores like Target and Walmart or at Best Buy and Circuit City. Durabrand are Walmart brand players that cost 25 or 30 dollars and they are easy to do as well.

Hope this helps

Cheers

Most of the DVDs available in India mostly use Region 2, Region 4 and Region 5 codes, all together in one DVD.

If you want something on the cheaper side try a Philips DVP5982 Multi-Region DVD Player.

hope that helps!
