How to downgrade Google search app in recovery? For some reason, I would like to downgrade the Google search app (com.google.android.quicksearchbox) to a older version, and upgrade later, on a MI 8 running Android Oreo.
But when /system is mounted in recovery, I couldn't find the Google app in /system/app, although other system apps are there.
I don't want to root the device, so how to?
some applications are in deferent locations, system/app holds certain applications while system/priv-app holds other's... sometimes your phone provider also puts apps in system/vendor/operator/APP_FOLDERS_BY_NAME   and custom/app/   

These locations change depending on device, but mostly stick to the same root directory's..   


system/app
system/priv-app
system/vendor/
custom/


Just have a look around at the different sub folders, and i think it's inconveniently named something completely different, like Velvet.apk
