Ok, I thought, I'm up for a challenge to change my 4s battery. It was harder than I thought. The tutorial and comments were helpful but it took me forever to get the screws back in the silver plate! After some time and frustration I figured out you need to " click" it back in! Once I got that the little gold thingy slipped right under the plate and voila! I got the screws in. Now I've done it once it should be easy next time! Word of warning; keep light pressure when handling screws until it gets matched with hole they kept flying off. Recommend putting white sheet/towel on floor way easier to find that way.
