Christmas greetings from the US all:
My W205 C300 lid also won't stay closed, due to a collection of things that slipped back there, and my trying to close it one too many times before extracting them. My problem is that I cant get the cover off no matter how hard I pull. Everything I can see has been removed. The video is poorly lit and narrated in Japanese, but he appears to simply pull it off the hinges. Am I missing something?
