iPhone 6(S)/Plus How does one update to iOS12 from 10.0.1

[mspman]

So I have an iPhone 6Plus that's been my trusty backup, and as such, I haven't kept it updated. It's still on 10.0.1. When I try to update OTA, no dice. Usually it hangs, sometimes it says "Your iphone is up to date" (albeit in Italian, but hey).

When I connect to iTunes on my MBP, it says it needs "a software update" before it can upgrade to iOS 12 but doesn't specify what that is. Then I click ok, wait for it, and then it comes back with "That update is no longer available from Software Update"..

So.. I'm in a pickle. I've heard good things about iOS 12 on iPhone 6 Plus so I wanted to give it a go.

Any ideas? Factory reset perhaps?

Do a backup then restore the phone. It should update to the newest iOS version.

I tried that

It restored my apps and data but didn't update anything on the phone itself.

Hmm not sure then.

What version of iTunes? Need 12.8 on Mac for iOS 12.

Also, I'd reset the phone to factory settings, then try update, then restore the backup.

And: is the phone jail broke? If so, might be something with that causing issues.

For some reason it's not working and at this point (mega time waster) it's not worth trying anymore. Just leave it on iOS 10 is my suggestion, especially since it's a backup phone.

thanks for sharing your experience. I too have a 6S Plus running iOS 10.3.3, and debated updating to iOS12. But I will just keep it now on 10.3.3. The apps can still update, but my AW3 can't work with such an old iOS.

Google “dfu update” - in theory that process should make the current firmware on the phone irrelevant and force an update to the latest version. It can be a fiddle to get the phone into DFU mode but worth persevering.
