How to download WindowsPhone OS on PC for install?

[Windows Central Question]

I want to download Windows Phone OS on PC as a image file for install with "Windows Phone Recovery Tool" where no WiFi or 3G internet. Like as iOS file.
iOS files for all Apple product can download on PC for restore or update with iTunes to Apple product.

There is no official way for it. Windows Phone 8.1 can be downloaded using nvfirm.

The Windows Phone Recovery Tool, when your phone is connected, will search for, find, and download the latest version of the OS for your phone. It will keep it saved for future use until a newer version is available. It will search for a newer version each time, and if no newer version is available, it will use the version that was downloaded the last time instead of downloading it again.

Been there, done that.

If you are wanting to manually download a different version, that isn't possible.
