I called a distributor(in Korea), he said it might be mainboard problem, if it is, it will cost so much (like 200 dollars) . I gave up.. cannot use this HD300 anymore..

Hi I tried to update flash memory using Line 6 Monkey and an error popped up. So I disconnected the USB cable and power of HD300. and when I turned on the HD300, the screen remains blank. How can I fix this? I tried to do Factory Reset by pushing A button while put the power on. Nothing happens. Now when I connect the usb cable between the unit and computer, The Line 6 Monkey detects the HD300 but I cannot perform Flash Memory update.
