When you were a kid, you may have toyed around with taking things apart. Then, putting them back together again. For me, more often than not, the put-back-together part ended with some spare parts. The lack of which did not seem to impact the assembled piece though.
Watch the GoPro Hero 5 undergoing the same procedure. JerryRigEverything takes a brand new GoPro Hero 5 apart. Usually, those videos are made so you can learn how to replace damaged parts, but sadly, GoPro does not sell spare parts for the Hero5. You’d need another dead Hero 5 for savaging the parts. Who knows, maybe GoPro will end up selling parts, or you can Frankenstein 2 dead GoPros into a live one.
