Need urgent Help! CowonJ3 hangs on booting!

Hello everybody!


Help! My MP3 player Cowon J3 hangs while booting!
Even a reset does not help. Then I used TCCTOOL and
did a firmware upgrade in flash mode. But the Cowon J3
still gets stuck at boot and is not recognized by the PC
as a drive.

One possible cause is that I have copied a l l the files of a
complete backup back to the player. Also the system files DID.bin
and nonce.bin! That's probably why the MBR is faulty.

My question: How can I reformat the drive or recover MBR again
so that the player boots again? Need urgent help!

Thank you so much for your answers in advance!
