Update iOS not possible

(iPhone 6s Plus)

I'm still getting the error message 'Software too old to install backup'. The iOS is 12.5 and will not update to a later version.

I have reset the phone a dozen times and STILL can't update or restore from my 'old' phone via iTunes.

I've followed all the instructions to the letter. But nope, it's still refusing to update.



iPhone 6 Plus, iOS 12

My mistake. It's an iPhone 6 Plus, not 6s Plus.


The iPhone 6 Plus is compatible with iOS 12.5 maximum, and cannot be upgraded to any version later than that!
