With reports that some people updating to iOS 10 were ending up with bricked iPhones and iPads, Apple Support has started suggesting users to go for iTunes-backed update to the new software in place of the over the air option. The iOS 10 upgrade started rolling out to all users from September 14.
While users on the latest version will get a notification in their settings prompting them to go for the 1.9GB download and upgrade, Apple thinks it might be better to plug in to iTunes and do the same instead. With the cases of bricking, it is not clear which devices are getting affected. In case you have ended up with a device that shows the dark screen, a fix is easy though you might end up losing all your data.
Here is what Apple is suggesting:
Restart device by pressing and holding the Sleep/Wake and Home buttons at the same time till you see the Apple logo. If this is followed by a “Connect to iTunes” screen, then you will need to reinstall iOS.
For this connect your device to a computer using the cable and a message will pop up saying: “The software on [your device name] needs to be restored to factory settings or updated.” Click Update to reinstall iOS and your data will be preserved.
For those planning the upgrade, it is a good idea to back up the devices fully before proceeding. Also, remember that not all devices are supported for the update.
The iPhone 4 series for instance is not compatible with this update, nor are earlier versions of the iPad and iPod. So check the list above before you puhs the button.
