Texturetool convert flipped pvr file in Unity3d

Question

I just convert png file to pvr file by texturetool . But that imported pvr file was vertically flipped in Unity3D. So, I can't replace it to the original sprite atlas(png file).

Here is the command that I was use to convert png file to pvr file

texturetool -m -f PVR -e PVRTC image.png -o image.pvr

Could you please tell me how to solve this?

Thank you

if you are doing this on runtime change Y tiling of your material. if you are doing it in the editor (just once) than you can use Pixlr.com for quick fix.
