My wife iPad updated to 17.1.2 . It is locked up . It will not power down to restart. The display says update to 17.1.2 with ok button but it will not work. Need help to release the update.

Hello Jamescannon123,

Please force restart the iPad:

1. Press and quickly release the volume button nearest to the top button.
2. Press and quickly release the volume button farthest from the top button.
3. Press and hold the top button.
4. When the Apple logo appears, release the top button.

This procedure can be difficult to perform the first time. Don't hesitate to repeat it.
