Updating iPad

Hi,

• Open settings > general > iPad Storage > Delete the software update (it may have a name like “iPad OS 15.4”
• Restart your iPad - Apple Support
• If updating with Wi-Fi, try to get closer to your modem for a more stable connection.
• Open settings > general > software update > download and install (Make sure your iPad is at 50% charge or higher. 20% or higher battery if connected to a charger)

A little hard to help/advise you when you provide little to NO useful information about your iPad.

Here are my questions to you.

Can you, please, confirm what year and model iPad do you have/own?

The “A” model number can be found on the aluminium back of your iPad, in very small print, right under the larger bold print “iPad” on the back of the iPad.

What iOS/iPadOS version is this iPad, currently, running?

What is the rated, internal data storage space/capacity of your iPad model and how much of this free, internal data storage capacity is left inside of your iPad model?

All of that additional info can be found in the Settings app, General settings panel, About.

Please try to make an attempt to answer all questions asked.

Thank You.
