This is probably the wrong place to post this, but this is the only place I could think of (It's not like I can post this in one of the guitar forums). I have a Roland TD-6 electric drum set, and while trying to update it, it ended up freezing on me. Turning the power off, unplugging it, trying to factory reset it, does nothing. When you turn it on, the buttons "song," "kit," "rec," "tempo," and "mute" are all lit. Does anyone have any experience with this or a similar product?
