Is there any method to decompile mod characters without it getting corrupted?

[. . .]

I want to decompile an abandoned mod character that I like and improve on the texture and make some skins for her, but whenever I decompile the texture it always gets corrupted.

Does anyone know any method to go about it without them getting corrupted?

If you're using ktools to decompile it'll probably mess them up. I'd suggest using textools or any other tex thingy bingy
