Are you making this selection on your device or when connected to the Desktop Software? If on your device, my advice is to stop...the on-device OTA update is, IMHO, dangerous. Rather, use the Desktop Software and then you can take a full backup to your computer, which will be forever preserved...the on-device update takes an on-device backup, but if anything goes wrong, that backup file is lost forever.
