XDJ 1000 MK2 CPU ERROR breaks hardware for doing update

I can't believe that because of disconnecting an usb by mistake in the middle of the update will make the hardware go wrong. No i bought the player used so I can't return them. The pioneer service representative in my area just told me this happen to xdj and cdjs players. It's unbelievable that such and expensive brand has this issue. I am so frustrated, $400 I have to pay to fix this wow. It blows my mind. Pioneer do better since you are overpriced!
