  1. Connect your iOS device to a computer that you’ve previously synced with iTunes.
  2. Select your device. If you don’t see it listed, force restart your device by pressing and holding both the Sleep/Wake and Home button for at least 10 seconds, until you see the Apple logo.
  3. If you made an iTunes backup of your device before updating to iOS 9, restore your device from that backup. If not, you need to make a backup of your device in iTunes, then restore from that backup.

If you still see the Slide to Upgrade screen after completing the steps above:

  1. Restore your device. If you don’t see your device in iTunes, or your computer won’t trust your device, press and hold both the Sleep/Wake and Home button for at least 10 seconds, until your device restarts and appears in iTunes. When prompted, choose Restore.
  2. After the restore is complete, set up your device as new.

This will be resolved soon in an upcoming iOS update.

As said in the third step, even if your device is facing the “Slide to upgrade” bug, you still can back up your data using iTunes and then restore it.

Perhaps it was due to many users trying to update the OS at once, which caused heavy traffic on Apple’s servers. However, the solution was to stop downloading iOS 9  and instead download the update from iTunes. But apart from that, users also reported that their device started to lag after the iOS 9 update.
