Flashing back MacBook 5,2

I have a Firewire camera that will runs on a MacBook 5,2. The system needs Boot ROM MB52.0088.B05.

I have a number of Macbook 5,2 running the camera wil no trouble. All have the Boot ROM I need and it works great.

However I have more Macbooks 5,2 that have Boot ROM MB52.0088.B06. Pre-installed with 10.6. These will NOT run my Firewire camera.

The camera locks up within 2 hours of use.

I have successfully flashed the firmware on one Macbook 5,2 and now it works fine. So I know it's the Firmware.

I'm using the command from this article.

If worked one time and I can NOT duplicate the procedure on more Macbook 5,2

I change hard drive between MacBooks and ran the same command.

Apple states the Boot ROM version is MB52.00088.B05.

How can I get these back to B05?

Can anyone help???
