Notes: Things Must Do before Updating to iOS 10

Things go wrong sometimes and making full preparation for unexpected things is always a great
idea.  We've received some reports from iOS users saying that they fail to update to the latest
version of iOS.  What's worse, some contents are missing after that.  Therefore, please make a
backup for your existing data on iPhone/iPad/iPod before you perform the update. 

Make a Backup Though iTunes

You can use iTunes to make an iTunes backup file on computer or to make an iCloud backup file
above the sky.  Just launch iTunes and plug your device in Mac/PC.  Then go to "Summary" page
by clicking on the "Phone-like" button.  Now, hit the "Back Up Now" button and it starts backing
up your device.  If you want to make an iCloud backup, please highlight "iCloud" on the left. 

On your iOS device, go to "Settings" > "iCloud" > "Backup" > "Back Up Now", and wait until
the backup is done.  Since the process may take a long time, you can enable automatic backup
service via toggling on the bar of "iCloud Backup".  It enables to automatically back up your
iPhone/iPad/iPod as long as it's plugged in, locked and connected to a Wi-Fi.

it's done.  Then, your device will reboot and you need to re-set up some information like Apple
ID, Wallet, Keychain, and so on. 

However, some users report that their devices keep restarting or being stuck on Apple Logo
when using this OTA way to update iPhone.  So, the latter two methods are more recommended. 

Note that if you're beset by the same situation, iOS System Recovery will fix your device to
normal without any data loss. 

Method 2: Update iDevice to iOS 10 via iTunes
