Thanks so now I think I need to customize my phone. But because my phone (sony ericsson w580) is not in the XS++ system, I need to download W580 custpack. And this is exactly what I did. I extract the w580 custpack files into the “own_custpack” folder in XS++ folder and I also make sure that the first folder in own_custpack is “tpa”. When I start the XS++ and at the cellphone model section I choose own custpack, at the region box it only shows up as \own_custpack and nothing else.
