This is how you update

Alongside the launch of iOS 12.4, Apple today released new versions of iOS 9.3.6 and iOS 10.3.4 for older iPhones and iPads that aren't able to run iOS 12.4.
The iOS 9.3.6 update is available for cellular models of the original iPad mini, the iPad 2, and the iPad 3, while iOS 10.3.4 is available for the cellular version of the iPad 4 and the iPhone 5.
Why the cellular models only? Because it fixes a GPS week rollover issue and only those models have GPS.
