Can't update iPhone 8 from iOS 12 (iTunes update button does nothing)
Hi. I have an iPhone 8 with iOS 12.4.1. When I try update via the phone's settings, I get the following message:
Let's go to iTunes then. I use a Windows computer with iTunes installed from de Microsoft Store, updated to the latest version (12.12.3.5). When I try to update from iTunes, when i hit the "Update" button, it does nothing.
Please, does anyone know what can I do to update my iPhone?
Thanks.
