Lg blue ray player Bh7530 region free code can

I don't think so.
When a DVD disc is created, it is encoded with a "Region number." The disc will only play on DVD players with the same Region number - for instance, a Region 3 disc won't play on a Region 1 player.
Region 1: U.S. and U.S. Territories, Canada
Region 2: Japan, Western Europe, Middle East, South Africa
Region 3: South Korea, Hong Kong, Taiwan, Southeast and East Asia Region 4: New Zealand, Australia, Pacific Islands, Mexico, Central/
South America
Region 5: Russia and the former Soviet Union, Africa, Indian
subcontinent, North Korea Region 6: China
The only way to get around the region codes, is to rip a DVD to your computer and remove the region code. Then burn the DVD to a DVD R. There are programs around on the net, but I'm not sure it is legal in all countries.
Google for the programs.
A DVD player sometimes allows you to change the region code once. But it not even would allow you to switch back after you changed it once.

anyone has a working solution? I have the same model and I have heaps of DVDs from Europe that do not play...

With your set on and without disc in the tray:

1. Press PLAY from your remote control
2. Press the following button sequence: 1590 2379 390
3. Press PLAY again

This will release the region verification in your player(region free). However, some DVDs (multi region in particular) will not play, since they require region detection from the player unit.

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

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

You may be able to get a region free code from one of these WEB sites.

To set DVD Region to “0”, download file “6000.zip” (often also called “LG6000.zip”) from here:

http://www.multi-region.net/_media/6000.zip

Save the file and then unzip and extract it to your hard drive.

Now burn the subdirectory RMTM0000 and its contents (not the text file) onto a CD-ROM (ISO format, “closed” CD-ROM).

Insert CD-ROM into the LG BD 370 P player, and when the Region Management System screen is displayed, set the Region Code to “0” using your remote. Once done, press “PAUSE” on you remote to save, and you’re done!
