Date

A newly published support document from Apple, which was first discovered by German blog Apfelpage.de, has acknowledged an issue where any 64-bit iPhone could be bricked by setting the date back to a specific time, causing it to fail to boot properly and requiring a physical repair to put the device back into working order.

According to the document, a permanent fix for the problem will be released as part of a future software update. Meanwhile, the affected iPhone owners are advised to contact Apple Support.

According to a post on Reddit and reports out of China, it is possible to brick an iPhone by setting the date back to a specific time.

I wasn't brave enough to test it myself, but the post claims the bug only affects 64-bit iOS devices.

It would seem that changing the device's Date & Time values to a specific point in time would cause it to fail to boot properly.

Basically, it gets bricked and stuck at the Apple logo boot image. Neither DFU mode nor restoring from a backup would bring a bricked device back to life as a physical repair is required to put it back into working order.
