I want to change some graphics in Unity .apk

Hi there!

This is my case:

In my workplace, before they hired me, they created an aplication, and now we need to chage the main logo in this app.

We don't have the proyect, only the scripts and the .apk, and I was wondering how can we change some sprites in the builded .apk.

Decompiling the .apk it and merging the shaderassets0 I can extract the specific sprites I wanted, and with the same software I can replace them, but after doing this I can't un-merge the shaderassets0 and the application crashes.

Using the "DevXUnity-UnpackerTools" I can open the .apk and see the "proyect", but this can't recompile the project without crashing.

I just need to change the app's main logo and recompile it for next tuesday.

Thank you all

 

Why do you not have the original project? Do you own this game?

 

My company be suposed to own it, but the old developer only send us the proyect scripts.

I'm suposed to chage the main logo and another in game logo, an in order to do this, I thougth that I coud do it without re-making the entire app.
