My D-Chord 361 dead after firmware upgrade. Soft recovery not working anyway. I try this step:
1. Main switch to "OFF".
2. Remove board from player.
3. Connect USB to player.
4. Short pins 29 and 30 on Flash chip, player recognized as USB storage.
5. Disconnect player.
6. Hold "PLAY" button and connect USB again.
7. Wait until player recognized as "ROCK USB".
8. Run ConsumerUpdate with the same firmware file from vendor site.
Player work!
Thanks to all, great site!
