The right way to change the extures of an android sport? (modding maybe?)

So, the query says all of it, however I’ll clarify additional.

So I’ve this sport put in in my cellphone named Monster Truck Destruction and for some time now, I wished to switch the textures of some vans, specifically this black and inexperienced truck seen under.

However I’ve searched EVERYWHERE any tutorial on how one can change the textures of an android sport however I discovered nothing. For what I consider it might have one thing to do with accesing the information and modifying them, which is one thing I actually wanna do however I havent discovered any tutorials or instruments up to now. So please, I really want some assist on this one.
