"Application not installed" error

[SlowSlyFox]

I'm new to the modding community and tried to mod some games. Changed some stuff there and here in libil2cpp.so, trown it instead of original and signed. Tried to install game on my phone and always get "Application not installed" error. Even when I just change libil2cpp.so without changes still get "Application not installed." Anyone haw toughts why this happening?
