Hi, UrAnus
I have the exactly same player. But it's too late -- I already upgraded the firmware even without a backup. The player is dead as you may expected. Though S1FWX can't extract a repairable firmware from the player. I want to have a try, what else can I do to a dead player? UrAnus, can you please extract your firmware and send me a copy to:

Thank you very much!
