Update: Here’s Apple’s comment on the matter:
We’re working on a fix for an issue impacting a small number of iPad units that are receiving an error when trying to update the software. We’ll issue an update as quickly as possible”
Apple has today pulled iOS 9.3.2 for the 9.7 inch iPad Pro, following reports that users were seeing their iPads bricked after updating to the latest iOS release on Monday. The bug does not affect the larger, 12.9 inch iPad Pro. After updating, users seeing the bug would be prompted to Connect to iTunes on the iPad display. However, aside from an Error 56 debug message, the device could not be restored through iTunes or DFU.
Apple acknowledged the issue yesterday in a press statement, suggesting affected users who cannot restore through iTunes should instead contact Apple Support. There is no word on a temporary fix for users who have already been impacted by the problem. It is likely Apple will re-release iOS 9.3.2 for the relevant models soon.
