Q: Unable to Install Update - iOS 9.3.5

I am having problems updating my iPad Air 32Gb

 

It is running iOS 9.3.3 and would not update to iOS 9.3.4.  Now it won't update to 9.3.5 either.

 

When I tried to update to 9.3.4, I received messages saying that the verification of the update had failed.  For 9.3.5, it just says "An error occurred installing iOS 9.3.5" but doesn't specify what. 

 

For for both updates, I deleted the downloaded update files and redownloaded them multiple times, to no avail.  It won't update via iTunes either.  The only advice I can see anywhere about these problems are to 1) download the update again - done and failed.  2) refresh or restart the device - done and failed.  3) update via iTunes - won't work either. 

 

I have several GB of free space and the problem occurs even when fully charged and whether plugged in or not.

 

My iPhone updated fine, apart from some glitches (with contacts and app crashing) that seemed to resolve themselves.   I understand these updates are important security ones, so am keen to get it sorted out. 

 

I would appreciate any ideas.  Other than suggestions to do what I already have done!

 

Thanks.

iPad Air Wi-Fi, iOS 9.3.3

    Exactly the same problem is happening with iOS 10.  Having no indication whatsoever what the problem is is not helpful.

    After reinstalling the Apple Mobile Device Driver in Windows and updating iTunes, it finally detected my iPad and completed the install.  I feel bad for those without a computer as there doesn't seem to be any fix for those without one.

     

    The installer must know what the problem is and is seems just lazy not to enable it to give an error code or explanation to users.

     

    Happy I solved my issue, but hope a more effective solution that works without needing to connect to a computer is found.
