Then you didn't get it into Recovery Mode correctly. When you get it into Recovery Mode, it will not ask for the passcode, it will just restore the device. Try getting it into Recovery Mode again. It can be difficult and it is not unusual for someone to have to try more than once. Follow the steps in the support document carefully.

What happens when you attempt to use iTunes. You will need to use iTunes to restore the device to remove the forgotten passcode. See the instructions here. If you forgot your iPhone passcode - Apple Support

You should be able to restore it with the Apple ID and password. And if that's forgotten, it can be reset.
