Set an old profile picture on Facebook - iPhone?

I want to use an old profile picture as my new one however when I set it as profile picture I have to crop it (even if it stays te same size) and sets the same picture as my profile picture but without the likes/comments which means I have two of the same photo In the album. How can I use the photo as my profile picture but keep all the likes and comments?

You can't. It refreshes each time, unfortunately

I think you need to do all that on your computer.

Sorry but unfortunately you can't do anything about it.
