What would be the issue if all my LG V20 does is boot loop. Any attempt to charge the phone/hit the button with a charged battery will immediately have it try and boot up , it displays the LG logo for a couple of seconds then it shuts off completely. then it cycles the process of turning on and off over and over. I somehow was able to get it to boot completely only once out of years of trying, it was short lived after i dropped the phone and the battery flew out ,and now im back to step one .
