The error instructs affected users to connect to iTunes, but doing so and attempting to restore or update the iPad doesn’t work.
Apple issued a statement to iMore to say the company is looking into it—sounds like another update will be coming along soon. The statement reads,
We were able to update our own 9.7-inch iPad Pro with no issues, for what it’s worth. If you were affected by this bug, let us know in the comments.
