Returning to factory stock all depends on how heavily YOU modified the device.
Here's some scenarios.
1. You rooted. Installed superuser. Installed titanium backup (or favorite app for backup) and backed up entire system. Then you modified with xposed, froze apps, or whatever you wanted to do with root access.
Now to return to stock you remove xposed, unfreeze apps, and undo whatever you did with root. If you changed anything system wise use titanium (or favorite app) to restore system files. Then in superuser click "full un-root". You should be back to stock now. Perform a factory data reset if you don't think your getting your phone back.
2. You rooted, installed superuser, busy box, and safestrap. In safestrap you made a nandroid backup and saved it somewhere. Then you wiped and installed a rom to some slot and had fun!
Now to return to stock place your nandroid backup in stock slot. Reboot and it should be back to stock with root. Uninstall safestrap and busy box. Now use superuser to do a full un-root.
3. You rooted and had fun! You forgot to backup anything and are now scared. You can go to see a Samsung rep at bestbuy and have him re-flash kit Kat for ya.
4. You rooted and had fun! But didn't back anything up and don't have a bestbuy nearby. You can search for an at&t service center. They can re-flash kit Kat for you.
5. You rooted and had fun! But didn't backup and there's no bestbuy or at&t service nearby. You can send your device to www.mobiletechvideos.com
and pay them to fix your fun. The process usually takes a week.
6. You rooted and had fun but no backups, no bestbuy, no at&t service, and can't afford mobile tech. You are now up the creek without a paddle. You have to wait for a restore nc2 thread, or Odin tar file gets released.
