Flashing NEC burners with Mac OSX

Thanks to Liggy and Dee for firmwares, and Liggy and Herrie for the necflash app.
See http://binflash.cdfreaks.com/#documentation for the general processes and for links to the software and firmware.

Download necflash.
Put the necflash app on the root volume, and put any firmware you want to use there as well for ease in specifying path name and location.

Open the Terminal App.

At the terminal prompt, enter
/necflash -scan
and hit return.

You must use the leading slash. You should see each device found and its letter name. I only have one DVD drive so the scan reported this:
Device : A:
and more info on make, model and firmware version.
You don’t need the additional info.
Device : {letter}: is the location/drive ID to use in other steps. It could be another letter depending on drive location. Mine is on Firewire and came up A: so I’ll use that as the example.

For dumping the existing firmware on the burner –
/necflash -dump /oldfilename A:

 where oldfilename is a name you're giving the dumped file, 
 and / puts it in the root volume.

For flashing with new firmware –
/necflash -flash /newfirmwarename A:
where newfilename is the exact file name of the .bin or .exe flash file,
including the extension, and the slash means it’s on the root volume.

In my case, flashing looked like this:
/necflash -flash /103bt_orig.bin A:

To query booktypes – /necflash -querybt A:

To set booktype –
/necflash -setbt mediatype booktype changetype A:
where mediatype is the media you’ll use, like DVD+R,
booktype is the type you’re changing to, like DVD-ROM,
and changetype is either Perm or Temp

The syntax is the same for all other processes. Happy writing.

Could you walk me through flashing my NEC 3550 with necflash? I tried to do it with necflashX and it does not work.
Thanks !!!

Please stop crossposting the same question in 3 different threads! :cop:
richiem already has written a detailled explanation on how to flash firmwares on NEC with Binflash.

If you are unable to follow his guide, I think it’s safer for your drive not to flash it at all!

Sorry … to much coffee
Here is what I am getting from terminal
It seems I’m having a problem with the firmware loading …?

Error opening firmware file
[Brandon-desktop-Computer:~] brandong%

This error message means that Binflash was unable to open the file “105bt_rpc1.bin” - you should either move the file to your home directory or use the complete path to this file.

I actually have the firmware and necflash at the root level (directly on the hard drive). Would it be better to put both on the desktop and direct terminal there?

OOPS !!! I was missing 1 slash in the command. Sorry … Everything is OK
