hi guy - if u tell, just a flash nothing more, then it seems to me it is another case which can be repaired with dfu. Well the thing is that till now nobody exactly knows the procedure. There are many of them - for me actually also worked one of them. So what I can suggest - you can read all threads dealing with "dead m3 player" and try. And - be patient and do not lose your hope as it might be a long way

But I dont want to shock U, so don't worry and good luck! Tomas
