Question [Q] Restoring Contacts and SMS from backups


I recently installed CM11 nightly, and it works fine.

I can't for the life of me figure out how to get my contacts and SMS back, i have an adb and nandroid (twrp) backup.

What ive tried so far,
- Titanium backup to extract it from nandroid and adb packages. could not find provider.contacts db in both...
- Nandroid Manager to restore apps and data, still not there.
- Tried reverting to previous nandroid backup but i get stuck on boot screen., had to go back to CM backup.

where the hell are they stored?
