I need original 2.16 firmware for NEC 3500A

I upgraded to 2.17 and now the DL function is really funky. I used to be able to run Nero DVD / CD speed and see the 4X graph. Now I get calibration errors with Verbatim 2.4X DL media. Also…the drive takes forever to recognize DVD media…especially the DL. Can anyone point me in the direction of the 2.16 firmware…I have serious doubts about 2.17.



Scroll down to Beta Firmwares for nd-3500a. what you want is “2.16 binaries and flasher”

Thank You!
