have tried all of the above, but no luck. well, i was very pleased to have the camera while it was working, starting to know that feeling of you'll miss me when i'm gone lol, defintely took it for granted!
will not lose hope, will send it to sherry or DAG, since i have another separate issue with my m6 that needs work too.
i have done some research, and came across this interesting post: http://www.l-camera-forum.com/topic/...rror-causefix/
have a gut feeling, that's what's causing it to fail. won't know until it's opened by an expert! thanks for the above suggestions though
