Your iPad may have entered recovery mode after a failed operating system update or another problem with the device’s software. You can also place the iPad in recovery mode yourself to troubleshoot or restore the device. When your iPad is in recovery, you can’t use it until you exit the mode. It’s possible to force the device to exit recovery mode without restoring. If that doesn’t work, though, you’ll need to restore the iPad in iTunes. Warnings Writer Bio
