Are you able to provide a screenshot where you are now on the device?

I loaded iOS 9 on my 4S with no issues. Used iTunes.

1. Connect your iPhone or iPad to a computer.
2. Open iTunes.
3. Choose your device in the iTunes window. You may have to force restart (hold power and home button for several seconds) to reboot the iOS device. This should make it show up in iTunes as usual.
4. Restore from a backup made before iOS 9. If you havent got a recent backup, make a backup now and then restore from that.
5. Although backing up and immediately restoring to that same buggy backup seems redundant, it actually flushes out the weirdness and when the phone boots again it will be able to complete the upgrade.
