iPhone recovery mode - error 14 - there is not enough space / storage to upgrade to iOS 14

It's because the phone has no more storage to update I believe but it already started downloading the update but just can't finish it (with iTunes).

Why doesn't iTunes report this problem, as there isn't enough space? Why allow the installation of a new version?

Why is Apple happy with so many dissatisfied customers who end up losing pictures and videos with their children?

No other reliable application / OS uses this deceptive strategy that allows you to update / install to stop halfway through the process and thus lose all personal data.

I think the strategy to sell iCloud needs to be changed, if there is a minimum of empathy ...

Please help the Apple community with an update that can delete extra applications so the phone with all precious data will work again.

Thank you!
