Samsung SW-240B OEM Firmware

Hello. I am the owner of a samsng sw-240b cdr/w drive. It turns out that I had the Dell OEM version of the drive, complete with firmware BD11. Without realizing this at the time, I tried to update the firmware with the standard Samsung R403 firmware. Now my drive is dead. It is recognized in the bios, but it does not run. I have tried to reflash with other Samsung firmwares, but the result is the same.

Does anyone know where I can get a copy of BD11 from? Is it possible for someone who also has this drive to back up the firmware and send it to me? I have been in contact with both Samsung and Dell tech support. Samsung says to ask Dell, and Dell has not been able to provide a solution yet.

Thank you
