OS update

That model number corresponds to a 2012, 1st gen iPad Mini.

A 2012, 1st gen iPad Mini cannot be upgraded beyond iOS 9.3.5 for WiFi ONLY models /9.3.6 for WiFi & cellular data models.

A 1st gen iPad Mini is a NEARLY 8-year old device, now!

These older iPad models are too old, now, too underpowered and completely incompatible with any of the current and future versions of iOS/iPadOS.

Also, these old 8 and 9-year old iPad models will be OBSOLETE by the end of 2020!

Sorry, but it is what it is, today, in the year 2020!

Here's why and what you will need to do about it in 2020!

Tap and thoroughly read my link below for my additional info about your old iPad model.

Sorry & Best of Luck to You!

You have a first generation iPad mini. If you have already updated to iOS 9.3.5/6, there are no additional updates.

Your very old first generation iPad mini can only be updated to iOS 9.3.5 (WiFi Only models) or iOS 9.3.6 (WiFi & Cellular models).

Apple ended update support for iPad mini in September 2016. Your iPad mini cannot be updated to iOS 10 or later major versions of iOS, as the internal hardware does not meet the minimum technical requirements for new versions of iOS/iPadOS. This limitation cannot be bypassed - in addition to which, iPad mini is a 32-bit architecture device, whilst all recent versions of iOS/iPadOS are designed for 64-bit hardware platforms.

You may wish to consider that compatible Apps for your iPad are increasingly difficult to find - as third-party developers are increasingly dropping support for older versions of iOS preceding iOS11/12/13. As older versions of Apps are removed from the Apple App Store, you’ll not be able to (re)download or install them - which may severely limit the usefulness and utility of your iPad if you should you ever need reset or restore your iPad. As such, if you want or need to access most current Apps, requiring more recent versions of iOS, you’ll need to consider replacement of your iPad with a newer or current model.

Of current models, even the entry-level iPad7 has specifications and capabilities that will massively outperform you current iPad - and is compatible with the vast majority of current Apps. Other models are more powerful still.

I hope this information provides helpful and succinct clarity as to your available options - and the limitations of your current iPad mini.
