Jack replied to me and provided me an English version of directions for the updating the N1 player as well as the firmware. I created another thread for that. I'll post the link below. Once he also give mes the N3 directions I'll post it accordingly. I'm sure its the same as the N1 however so you can just use the update directions in correlation with the N3 firmware available :).
