I attempted to do the hacking to unlock the hidden features of my md. The features did become unlocked but I have several problems. The volume buttons don't work any more, not on the unit or the remote and it's always on full volume. The play/enter button, when I press it, the screen changes to some weird bar that looks like S---=---F. Other than that, it's all good.
When I tried to enter service mode to fix it up, I couldn't. I'm sure my key sequence isn't wrong because I wasn't able to enter service mode before. I understand that I don't hold down the volume down button but the group button. My software version is 1.600.
