I'm on Nougat and I'm trying to install the latest Play Store, since it refused to update by itself. I renamed the old one's extension and tried placing the new k one in /system/priv-app and setting the permissions. Rebooted. No dice. Still the same old version. Tried a recovery-flashable zip. Still the same old version. What am I doing wrong? The permissions and file location are correct, so I'm at a loss here.
