Was attempting to change the screen in an ASUS zenfone 3. I was following the instruction off of youtube when I got to the battery removal part. I had done everything the instructions demonstrated. As I began to pry the battery out. I witnessed a spark then the battery burst into white-hot flames. This is a photo of the aftermath. I have changed many components on many different devices. To boot I have built 14 computers from the CPU on up this is the first time I have had something burst into flames when I was working on it.
