I recently got a Busman mod. HD-P2 from a friend. I purchased an external battery and was trying to see how long it would last running mics. The plug for the external battery comes out rather easily and I knocked it out while the thing was recording. The unit loses power and I turn it back on. Now none of the buttons, except for the power button, are working. When I go to power it down, I have to hard power it down and it doesn't ask me to hit select, like normal. Anyone ever heard of such a thing?
I should also mention, that I upgraded to the latest firmware right before that, but I wouldn't think that would have anything to do with it.
