Maybe. Or Maybe Not. There's no guarantees. Bit, if you were to restore from the backup, it would have to be from one of the current iOS. So, always create a backup, prior to updating and after updating.

"Can’t Turn On WiFi: WiFi has been completely greyed out for over two hours now. I’ve tried resetting my Network Settings, restarting my phone, and changing my settings. Not sure what to do now, any suggestions?"

If Wi-Fi is Greyed-Out:

Try The Following in the Order Provided:

A. Restarting the iPhone:

If any changes were made (i.e. Installed Apps), then Settings (i.e Wf-Fi), may have become manipulated technically. So, try restarting the iPhone:

1. Go To: Settings
2. Tap: General
3. Tap: Shut Down
4. Slide: Your Finger to the Right

B. Disable Cellular:

Try disabling Cellular, and using Wi-Fi instead, seeing if that makes all the difference. Cellular always overrules Wi-Fi.

C. Try manually restarting your iPhone:

1. Go To: Settings
2. Select: General
3. Scroll to: the Very Bottom
4. Select: Shut Down
5. Slide Finger: to the Right
6. Wait: 30 Seconds
7. Power One: the iPhone
8. Try this Once More

D. Reset All Network Settings to Default:

Example of items that will be reset: (Wi-Fi Passwords, VPN Connections, etc)

1. Go To: Settings
2. Tap: General
3. Tap: Reset
4. Tap: Reset Network Settings.
5. Enter: [Your Passcode]

As a Last Resort:

E. Restore form a Backup:

Have a backup of your iPhone? If you are not concerned with losing data, then restore your iPhone from a backup that was made when Wi-Fi was working. Prior to restoring, backup your iPhone, incase anything goes wrong with the restoration.
