Ok they've fixed it!

I also took it to some lab and they're having hard time finding it, they have the code but for some reason it simply doesnt work. They still managed to change zones if they tried, but the multi-zone hack simply doesn't work. Anyone got more ideas?

So I've tried some stuff I found on the web but nothing worked. Anyone got any idea how I can open my DVD1 B&O to be multi-region player? Thanks in advance!
