@nobitamonishc sounds like you are looking for help on changing your screen. iFixit doesn't yet have a guide for that, but here are some [https://www.nadiemellamagallina.com/en/manuales/smartphones-1/xiaomi-191/xiaomi-mi5-588/pantalla-completa-4610|good directions]
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.
