wht do I do when my fiio m6 stops working or charging

moshe tzvi bolel always check your charger and charging cable first. Then check the charging port. Make sure it is clean and no pocket lint etc in there. A few puffs of compressed air will usually clean it. If that does not work you want to open it up and replace the battery Fiio M6 Teardown. While you have it i open, inspect the charging port to ensure the solder connections etc. are all still connected. If a new battery does not work you may have to replace the charging port which appears to be soldered and hard to come by. Post some good pictures of what that all looks like so we can see what you see. Adding images to an existing question
