My sister's iPad somehow has been disabled (she said the passcode wasn't working, and she can't get it right, I don't know her passcode). I'm trying to restore it using iTunes on Mojave and it's not working. Downloaded the Software update it comes up with to sync with iOS device, and it's just showing up as an iPhone. It will still download iPadOS 13.6 but it says the firmware is not compatible with this device. Downloaded the IPSW from another source and also nothing. Not sure what to do now. If anyone has any ideas please let me know because this is already tiresome.
