Q: The ios 8.1.2 will not update. I select agree and nothing happensx

Hello ldscafl01,

If I understand correctly you are updating the iPad from the Settings app but tapping Agree to start the installation does not make anything happen. I would recommend quitting the Settings app:

iOS: Force an app to close

Double-click the Home button.

Swipe left or right until you have located the app you wish to close.

Swipe the app up to close it.

When you have done that restart the device and test the issue again:

iOS: Turning off and on (restarting) and resetting

You can also use iTunes to update your iPad as an alternative:

Update the iOS software on your iPhone, iPad, and iPod touch

Update your device using iTunes

If you can’t update wirelessly, or if you want to update with iTunes, follow these steps:

1. Install the latest version of iTunes on your computer.
2. Plug in your device to your computer.
3. In iTunes, select your device.
4. In the Summary pane, click Check for Update.
   
5. Click Download and Update.

If you don't have enough free space to update using iTunes, you'll need to delete content manually from your device.

 

Find out what to do if you get other error messages while updating your device.

Thank you for using Apple Support Communities.

Cheers,
