How do you change the app store's large icon on iTunes connect?

Yes, editing of large icons that are already in use by iTunes Connect is locked, but however, You can still register a new update to Your app, in which You can upload Your new 1024*1024 icon
:)

Hi,

I think, no need to upload a new build. Sorry, it's in French, but I think you get it. You need to scroll a little bit but there you can upload an image file. Best is PNG and size 1024x1024.

I found out that you can change the large app icon if your app is not on sale yet - but the place to change it is well hidden.

1.click on the app in itunes connect
2.click on "view details"
3.click on "edit" button next to Version Information at the top of the page
4.scroll all the way down
5.change icon
