iPad will not install update 14.2 after updated

You might have an iPad that, because of hardware incompatibility, cannot support the current iPadOS version 14.2.

Identify your model:--> Identify your iPad model - Apple Support

then see this list of compatible models:

If your iPad model has been stuck on iOS 10 for all of these past years, then you own an over 8-year old, 2012 iPad 4th generation.

That iPad model cannot ever upgrade beyond iOS 10.3.3/10.3.4.

Your over 8-year old, iPad 4th gen model is too old, now.

Apple ended support for 8-10 year old iPads, at least, over 3 years, ago.

The internal hardware in that iPad is too old, too underpowred and completely incompatible with all later versions of iOS/iPadOS.

Virtually, all third party iOS app developers ended/stopped/abandoned supporting these old iPads over two years, ago.

There are virtually, NO MORE older iOS 9 or 10 compatible apps available from the Apple iOS App Store, any longer.

Simply put, your 4th gen iPad is too old and obsolete now.

Sorry.

If you need/want an iPad with an up to date iPadOS with access to current, updated apps, then you really need to seriously consider a new iPad model OR a much “newer” , used iPad model capable of running the latest iPadOS versions.

There are plenty of newer, older iPad models that can run the latest, current versions of iPadOS.

Sorry & Best of Luck to You!

What error are you getting? are you trying to update it wirelessly?

See this support article:--> If your iPhone, iPad or iPod touch won’t update

If the issue persists, update it using a computer running iTunes.
