However, OTA installations often lead to "iPhone won't update to iOS 14" issue, either due to weak Wi-Fi network/internet connection signals during the update, or accessing the Apple servers when they are busy due to a large number of users trying to upgrade at the same time, and so on.

Here are the steps for updating to iOS 14 using iTunes:
