Ipad Air model md785ll/a with software version 12.5.5 and I need to update its ios to 15.x is this possible

If you decide to go down the path of purchasing used, secondhand Apple devices, from individual Apple device sellers, here is how to avoid purchasing an Apple iOS/iPadOS device with user activation lock, in the future.

If you purchase any iPad, or any Apple iOS device, for that matter, used/second hand, online, or even in-person, make sure this iPad does NOT have user activation lock and has been properly reset for sale.

A properly reset for sale iPad should initially power up to an animated, multi-language “Welcome” screen.

DO NOT take the iPad seller's word that this iPad is user activation lock free!

We have seen plenty of used iOS device purchasers get scammed.

User Activation Lock can never be bypasss, circumvented or worked around IF there is no correct previous/original user information to be able to do so.

Apple doesn't get involved with ANY user activation locked, used/second-hand sold devices, either.

So, buyer beware!

If purchasing a used device in-person, power the iPad ON

If the iPad DOES NOT display the initial animated, multi-language “Welcome” screen, then pass on purchasing this iPad.

If the iPad powers up to any other screen, then forget purchasing this iPad.

You cannot trust that the seller actually has the correct needed info to properly reset the iPad back to factory settings right then and there before the actual purchase and exchange of money for the iPad, in question.

Pass on the device!

If you are purchasing this used iPad online ask the seller to provide multiple images, either online or be sent to you via email, showing this animated, multi-language “Welcome” screen of the interested in purchasing iPad model.

Even better, ask for a short video be sent to you showing this animated, multi-language “Welcome” screen, in action and in its entirety, posted to the online ad or emailed to you.

If the online iPad seller refuses any of these requests, pass on the iPad. DO NOT buy!

Good Luck to You!

In short, no.

The first generation iPad Air, iPad mini2 and mini3 can only be updated to iOS 12.5.6.

Apple ended major update support for these models of iPad in September 2019 - although they continue to receive occasional “point” security updates, the most recent being released August 2022. These devices cannot be updated to iPadOS 13 (or any later major versions of iPadOS) as the internal hardware does not meet the minimum technical requirements (CPU capabilities and available RAM) for newer versions of iOS/iPadOS.

Some App developers have dropped support for iOS versions preceding iOS 13.x for technical reasons (often because APIs or software libraries upon which they rely have been updated in the new version of iPadOS, making their App incompatible with earlier versions). 

Whilst many App titles remain compatible with your iPad, if you want or need to access to Apps requiring the most recent versions of iOS, you’ll need to consider replacement of your iPad with a newer or current model that supports iPadOS15/16.

That model number corresponds to a First Generation iPad Air which is not compatible with iOS 13 or later.

You can update to iOS 12.5.6, but that is as far as it can go.

No and never.

Sorry.

The 2013 iPad Air 1 ( “A” model number A1474/1475/1476 ), iPad Mini 2 ( “ A” model number A1489/1490/1491 ) and the 2014 iPad Mini 3 ( “A” model number A1599/1600/1601 ) cannot upgrade beyond any version of iOS 12.

These iPad models have overall internal hardware that is too old, too underpowered and incapable of running all of the new, advanced and internal hardware resource intensive features of the newest iPadOS versions.

These iPad models are 8 and 9-years old, now, in 2022.

Sorry.

Third party app support, typically, continues for 2-3 years AFTER Apple ends full support of a subset of their devices.

The last major update to iOS 12 was in 2019, with iOS 12.3.

Apple has stopped issuing any major iOS 12 updates for these very old iPad models and have been ONLY issuing security, “point” updates for the past few years.

So, year three is coming to an end and third party app support has been on a steady, downward/decline trend for all iOS 12 supported devices.

Many popular third party apps are no longer available to 9 to 10-year old iPad models that are, permanently, stuck at some version of iOS 12.

Look for many more third party apps dropping support for all iOS 12 supported devices as the 2022 year progresses to its end and into the beginning of 2023.

The immediately above statement is what you really need to worry about.

In addition, the various iOS 12 Web browsers that were available for these older iPads should still be safe to use for a while longer, you can still use that iPad the way it has always been used, but know that 8 to 9-year old iPad model will no longer have access to any current apps.

Plus, no way to know when Apple will cut of all security support for these 8 and 9-year old devices.

Also, the internal, rechargeable batteries in these old iPads are, also, running on borrowed time.

Not worth the costs to replace these old internal, rechargeable batteries in these old iPads, any longer, either.

Also, these very old iPad models have NO real trade-in nor any resale value, either.

Sorry.

You need to consider that it is the Fall of 2022, now.

iPadOS 16.1 is here!

These 8 to 9-year old, iOS 12 iPad models are coming to the full end of their support life.

These iPad models will be 4 OS iterations behind, now.

You really need to seriously consider a purchase of a new iPad model OR a much, MUCH “newer” and less expensive, refurbished or used iPad models, from better known, trusted sources, like other Apple product/device retailers/resellers, some locally or from online, on the Web/Internet, capable of running the latest iPadOS versions.

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

If you need OR ONLY able to afford to purchase older, less expensive iPad models, look at older IPads from 2015 and later.

All of these older model iPads below CAN, currently, run the latest releases of iPadOS 15 and the up and coming iPadOS 16, releasing early next week.

2015-2017, 12.9 inch screen iPad Pro models. ( 1st gen Pencil support )

2017, 10.5 inch screen iPad Pro models ( 1st gen Pencil support )

2017, 9.7 inch screen iPad 5th gen models ( NO Pencil support )

2018, 9.7 inch screen iPad 6th gen models ( 1st gen Pencil support )

2019, 10.2 inch screen iPad 7th gen models ( 1st gen Pencil support )

2020, 10.2 inch screen iPad 8th gen models. ( 1st gen Pencil support )

2018, 11 inch or 12.9 inch screen iPad Pro models ( 2nd gen Pencil support )

2019, 10.5 inch screen iPad Air 3rd gen models ( 1st gen Pencil support )

2019, 7.9 inch screen iPad Mini 5th gen models ( 1st gen Pencil support )

Get the largest internal data storage model you can afford as NO Apple iOS device has ANY expandable storage.

I am sorry that you had to learn all of this, but this does not change any of the facts regarding these older iOS devices.

Sorry & Best of Luck to You!

An unit running any version of 12.5 isn't capable of 13 or above.
