LG G4 bootloop temporary fix to back up data successfully
~Try these at your own risk~ 2016-07-26 Story - After playing Pokémon Go for an hour in a modestly humid evening, the phone (507, manufactured 7/2015) felt hot as the battery was draining. After getting home with air conditioner on, the phone was left with Pokémon Go, WiFi, and Chrome browser on. However, it went into the infamous bootloop after the phone was sitting on the table, with those aforementioned applications opened, for about an hour. Fixes - Tried 2 methods, freezing the phone in the freezer, and used a hair dryer to blow the phone until it becomes quite hot. Both approaches worked, but hair drying the phone worked more effectively.
