Apple this morning recognized the bug whereby if you change your date to May 1970 or prior, you won’t be able to restart your iOS gadget. The bug affects all iOS gadgets that use a 64-bit chipset.
As an update, the bug in the operating system basically depends on a user resetting a gadget’s date to any date sooner than May 1970 (earlier reported as just January 1 1970). When set, if the gadget gets rebooted it gets permanently stuck. Connecting it to a PC in iTunes or booting into DFU mode appears to work but doesn’t really fix the issue; the device remains bricked. In fact, except from some random anecdotal proof, there doesn’t appear to be much that a user can do to fix the issue. Some have recommended the gadget recovers by itself after a number of hours, while others claim to have had achievement in reviving their phones by switching out the SIM card.
Regardless, a few people have also attempted to rope users in with different graphics claiming that setting the date to January 1, 1970 will unlock an Easter Egg inside iOS and set a “classic Macintosh theme”. Although this bug won’t do anything on non-64-bit chip iOS gadgets, anything from an iPhone 5S to the latest 6s Plus, and also all iPads beginning with the original Air, and recent gen iPod touch will get “bricked” if you apply one of the tricky dates. As far as operating systems, the flaw has reportedly been affirmed on all versions of iOS from 8.0 up to 9.3.
The post on Apple’s site expresses that “a forthcoming software update will keep this issue from affecting iOS devices” and that if you have this issue, to contact Apple Support.
