My iPad is unable to check update, I already did everything but the latest version on my iPad is 10.3.3

Hello,

If your iPad will not update past 10.3 then you have an iPad (4th generation). This iPad model does not support any system version newer than 10. You cannot update your iPad any further. If you need to use an application that requires a newer system software version then you will need to purchase a newer iPad model.

If your iPad has been stuck on iOS 10.3.3 for the past few years, with no upgrades/updates forthcoming, then you

own an iPad 4th generation.

A 4th gen iPad cannot be upgraded beyond iOS 10.3.3/10.3.4.

A 4th gen iPad is an over 7-year old device, now!

Its internal hardware is too old, underpowered and completely incompatible with any current and future versions of iOS.

Sorry. It is what it is.

If you need an iPad that can run the latest and greatest versions of iOS, as well as, the most current apps available, then, you will need to purchase a new iPad from Apple or a discounted, refurbished iPad from Apple’s Refurbished & Clearance section of Apple’s Website.

Best of Luck to You!

The iPad 4th generation cannot be updated beyond iOS 10.3.3.
