[AC Question]

I have a OnePlus One CM11 rooted.

I "played" a little bit with my phone with those things:
1) \System\priv-app\ContactsProvider.apk
2)ContactsStorage from Setting ->Apps->All->ContactsStorage

Somehow I ended up with the situation that:
1)ContacsStorage does not appear at the apps list.
2)The directory \data\data\com.android.provider.contacts have disappeared.

I know that reinstalling the rom will fix it, but I'm trying to avoid it.
Do you know of any other way I can do it?

There are a few different Contact apps in the Play Store, or you could ask whether the apk is available standalone at CyanogenMod Forum.
