I accidentally installed the wrong version of Google Play Services via an apk, and now it's crashing every 5 minutes and the Google apps don't work. I tried installing the apk for the right Google Play Services, but it won't install (I think it's because of the signature problems). The apk install screen just has an "x" saying "app not installed." I can't uninstall or disable the old/wrong play services.
Maybe helpful information:
Nexus 4, CM 12.1
The correct version is -436, right?
