How can I change my Facebook profile picture back to a previous one and keep the likes?

[Cillian]

I uploaded picture a today with 10 likes. I want to change back to picture b with 50 likes. Every time I try to upload a new photo from the album profile pictures and clik on picture b, it tells me to crop it, and then once it's uploaded a separate picture b with no likes is created. How can I get picture b with the likes as my picture? On iPhone

the only way to keep the likes and comments is to find that picture already in your profile pictures album, and select for it to again be your profile picture.

you cant upload it again and keep the likes and comments, because it's technically a new picture, even tho it looks the same

You go into your album "profile pictures" then select the photo you want as your new profile pic and change to profile pic, it should say "you have had this picture before are you sure"...something like this and bingo it will keep the previous likes and comments....well this works for me on my laptop
