Need help on Gangstar Miami Vindication image files [pvr]

[D0GE_the_D0g]

The pictures used in Miami Vindication are saved as pvr format and PVRTextool can open them well, but when I turn a PNG back to pvr and put it back to the game folder, it can't be read at all. So I wonder if anybody can figure out how to modify those pictures and make them readable by the game.

I managed to solve it myself……It's just a bit depth problem
