Alright, i love my v20 so I kept it and was just using it as a back up phone since it got outdated and became laggy. Never messed with the software or anything, all stock. Didn’t even get an update from where I am. it’s still in Nougat. Now it went to a bootloop then got the error message from the first pic. Saw a video on YouTube, said all I need to do is to connect it to LG Bridge and do the update error recovery, I’m not sure I was able to finish the process because my phone restarted and I was able to use it for minutes, literally. Then this green screen with the heading app watchdog bark appeared and I can’t seem to find a solution for it.
Captain, are you there?
