My son opened the tray, put some cookies and closed the try. I was able to take most of them but still there are some inside. I saw three screws in the back of the device so I took out them but I can’t take out the cover.

cookies in a tray…………..why he just didn’t give me some? anyway i have no idea how exactly that BluRay player is buildt but from my experience i think it could be some clips arround and the metal part should slide out this black metal should slide out (you need to lift it like 30-60 Deg then just pull on it ) if that dosen’t work there may be some screws holding it inplace maybe try to pop that front cover up i don’t think there are some adhisives or glue or anything like that i preffer some gloves on that one and maybe add an repair manual to ifixit?
