1. ADB Pull the APK you want to edit.
2. Make a backup of the APK just in case.
3. Open the APK in 7zip and drag the "res" folder to your desktop.
4. Edit whatever PNG file you want.
5. Drag the "res" folder back into 7zip to replace.
6. ADB Push the APK to your phone (best to do this in recovery mode with system mounted)
7. Boot up and enjoy!
