Following multiple complaints that the iOS 9.3.2 software update, which released two days ago, has bricked some 9.7-inch iPad Pro models with ‘Error 56’, Apple today acknowledged that it's aware of these reports and is “looking” into them.
Although Apple's statement to iMore does not make it clear whether the company has pinpointed what might be causing this issue, the company did advise those unable to restore their device through iTunes to contact its support team.
