Cannot restore firmware

I have a problem with my 2009 Macbook Pro 13".
It has crashed during a firmware update, and now it won't boot but only beeps "SOS".

I went to a couple of Apple Service Providers, but they could not help me restoring the firmware, the only solution seems replacing the logic board.

Does anyone have some tips about other things i could try?
Thanks

Have you called AppleCare?

Yes i have, they could not help me and only said i had to take it to a service provider.
They are not willing to repair this issue under warranty, despite it is caused by an official firmware update. So it looks like i have to pay for a new logic board only because the firmware has to be flashed.

In some cases you can restore the firmware yourself. See if this helps:

Yes i know.
The page however, describes you need to find the right version of the firmware restoration image, but my macbook pro (macbookPro5,5) is not listed in any of the (1.4 ~ 1.9) versions.
Seems to be a dead end..
