@paulmiki Since iFixit does not yet have a guide for this, use something like [link|https://www.youtube.com/watch?v=UxFG72xbS2E|this video] to replace it. Replacement screens are readily available at many online stores. Purchase one from a vendor that appeals to you.
While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same problem as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
