iPad won't update past iPadOS 14.7.1, stuck on downloading 15.1 at 0% for days

[christianmdu117]

I have an iPad 6th Gen LTE running iPadOS 14.7.1 that is stuck on 0% downloading 15.1:

Looking at the Troubleshooting log, I can see the download taking place, but not getting past 0% (this is repeated over the past couple of days):

The user has tried restarting their iPad but this hasn't helped. The iPad is plugged into a wall socket (battery level at 100%), connected to stable Wi-Fi and has plenty of available free space (12 GB). 

I came across https://support.apple.com/en-gb/HT201435 which says you can delete an update by going into Settings -> General -> [Device name] Storage and tapping "Delete Update". I'm going to try this next, with the user when they come to see me. 

Has anybody experienced anything similar in the past?

I've seen this behavior if you set the RecommendationCadence to block the iOS15 upgrade visibility from the user.   Basically, if RecommendationCadence blocks iOS15, MDM commands can't force the upgrade either.

Thanks, and where would I find if we're blocking iOS 15?

Hi christianmdu117,

It depends, but a basically a custom command like below is sent to the iOS device. This can be done automatically via Workspace ONE Intelligence Custom Connector.

<dict>
  <key>RequestType</key>
  <string>Settings</string>
  <key>Settings</key>
  <array>
    <dict>
      <key>Item</key>
      <string>SoftwareUpdateSettings</string>
      <key>RecommendationCadence</key>
      <integer>1</integer> 
    </dict>
  </array>
</dict>

I managed to resolve this by going into Settings -> General -> [Device name] Storage and tapping "Delete Update".
