The BH20N is an OEM version of the BH08NS20 and yes you can crossflash your BH20N to its LG retail equivalent.

The problem is that the latest available retail firmware for the BH08NS20 is 2.00 (released 2009-10-31) which is still quite old.

What you could do instead, is to crossflash your BH20N to a BH08LS20, for which a newer firmware is available (v2.00-03 released 2011-05-02). Such crossflash will not enable Lightscribe (as unlike L/LS drives, the N/NS drives do not have the necessary hardware for it to work), but at least you’ll be able to take advantage of the newer firmware which has better media support than version 2.00 for BH08NS20.

In order to crossflash your drive, load the firmware in MCSE, tick the relevant boxes you want (increase speed, auto RPC2) and then press save. That will create a new crossflash ready ‘speedpatched’ file. Use this ‘speedpatched’ file to crossflash your drive. Turn off your computer (just restarting might not do the trick as not all mobos cut off the power to optical drives during a simple restart, and LG drives need this) and on restart your drive should identify as a BH08LS20.

thanks for the info i tried getting the firmware you recommended but after following your instructions when i try to flash it all that comes up in the list of selectable drives is my virtual drive and not my actual bluray burner as can be seen here

Maybe the flasher doesn’t support Windows 8 (assuming that’s what you’re running by the looks of the screenshot).

i trid it in my other pc (windows 7) after i posted thinking the same but no luck with that either the flasher dose work under win 8 though i updated the normal firmware from dell the first day i got the drive from c105 to c106

its is frustrating though when you buy a bluray burner that fails to detect blank bluray discs lol

Try using DevilsClaw’s Flasher instead: http://forum.rpc1.org/viewtopic.php?f=2&t=46137

Use the -r command on the speedpatched file provided by MCSE in order to rip the main firmware from the flasher package, and then the -f option to flash the main firmware to your drive. You don’t need to flash the core. Make sure you shut down completely your computer after you flashed the drive (as opposite to a simple restart).

You might want to let ala42 know that the crossflash option for this drive doesn’t work properly…
