So I broke the screen on my Huawei Mate SE, and being that I repair PC's and Laptops for family and friends, and that I've repaired phones in the past from about 3 generations prior, I figured that I could handle a simple screen replacement. I was wrong. The online tutorials were very poor, out of focus, and largely lacking directions. I was doing pretty good, however, until I had to remove the battery (You have to remove the entire phone assembly to reach the screen and frame). The battery was taped in, so as I was cutting the tape, I slipped and punctured the battery. It started shooting out sparks and erupting internally. Thankfully, I stayed calm and made sure it didn't catch anything on fire. I took it outside and placed it on my front porch to cool off in the freezing air. Once it cooled down, I took some photos of the damage and bagged it up to dispose of at a later date. So I guess I learned that most modern phones aren't really meant to be repaired. Looks like I'm buying a new phone (Same model, pretty cheap), but I did salvage the motherboard so I should be able to slot it in and still have my data. Photo below.
