Some people are very publicly complaining, however, taking to Twitter to claim that iOS 9.3.2 has bricked their iPad Pro devices.
 
The usual way to update an iDevice is what’s known as OTA, short for Over The Air, where you let your current version of iOS download the bits it needs to complete the update and then apply the needed changes.
 
This is usually a lot more efficient that downloading a complete firmware image, because you don’t need to fetch parts that haven’t changed. (Our update, from 9.3.1, was an 89MB download, a tiny fraction of the full firmware’s 2.08GB.)
Nevertheless, there’s always that worrying moment when you know your old iOS version is about to shut itself down and the stitched-together new version is supposed to boot up in its place…
 
…and at least some iPad Pro users seem to have got stuck right there.
