Basically yeah, thats what i did. Although i had a little help from a member on this forum who was having the same problem with an identical player and had found a compatible firmware file for his that worked in mine. Sometimes you'll find that the firmware you've flashed is totally incompatible and the player isn't recognized in windows. Just perform the 'dead player recovery' to get it back into ADFU mode again and try a different firmware.
