Anyone know about this?
If it's totally disabled and you cannot get into it, you can reset the iPad by holding down the power button and the Touch ID button at the same time for about 15 seconds or so. When you see the Apple logo appear let go of the power button and keep pressing the Touch ID. You should see a request to connect your iPad to your computer. Go into Finder and locate the iPad and from there you should be able to restore it. You will lose all of your data on the iPad. Hopefully, you have a recent back-up to restore it. Good luck!
I have no idea how to do this on the iPads that don't have Touch ID. Probably pressing and holding down the power button and one of the volume buttons will work.
*btw, ignore the trolls in this topic. It's ok to ask a question even if google can produce an answer. From my experience google isn't always the best at answering questions.
