I took out the battery and logic board on my iPhone 5 due to water damage. Placed the screws on a screw map. However, my spouse came home and moved it. Rearranging all of the screws I had neatly placed. What should I do?
You’ll need to go through the guide carefully and note which screw goes where, the guides are very good about screw sizes: iPhone 5 Logic Board Replacement
the 2 screws needed to remove the battery cover has both the same size screws so it dont matter and plus the battery will be fine without them
