Locked is when the screen is black and the device can’t be used. Unlocked is when you have the device such that you can tap on the apps. “Logged in” might be another way of saying it. When gphoto tries to connect, the iOS device (at least the newer ones) will ask you if you want to “trust this computer”. If you say “don’t trust”, then the iOS device will report no photos on the device. If you choose to “trust this computer”, then the photos will show up.
