Apple’s latestcomes with a significant pack of bug fixes and improvements, and while installation takes place smoothly on the iPhone, it appears that a number of iPad users are actually experiencing problems with the update.
Some 9.7-inch iPad Pro owners have reported that the iOS 9.3.2 update breaks down their devices up to the point where nothing seems to work, with the traditional workarounds and recovery methods making no difference.
writes that these devices are stuck with Error 56, which, according to Apple’s own documentation, might be a hardware issue. In this case, however, there is no hardware issue, and users are recommended to try various workarounds before eventually contacting Apple support staff.
Try this before contacting Apple
Apple says that you should check if you have the latest version of iTunes, remove any third-party security software on your PC, make sure that you use a working USB cable (the one that shipped with your iPad is the recommended one) and to try restoring your device twice. If nothing works, then contacting Apple is the only option.
This isn’t the first time when Apple ships iOS updates that brick devices, and the most recent case happened when the company pushed iOS 9.3, causing some issues on the company’s newest iPhone models., but there were also several other issues, which Apple had no other choice than to correct with another patch released only a few days later.
This is most likely what Apple needs to do this time too, although the company is yet to publicly acknowledge the problem. It’s also unknown how widespread this issue actually is, but given the fact that the latest iOS update is still being shipped to iPad Pro units, Apple most likely sees the bug only a handful of devices.
In the meantime, make sure that you back up everything before installing iOS 9.3.2 on iPad Pro units, just in case something goes wrong and you need to recover at a later time.
