firmware KO

Hi everybody,

I am using a Q2501b device and I had a problem in target mode.
Now my firmware is KO and, in my documentation, Wavecom says that I have to send back the device to the factory so that they can reload it using a special cable (to acces Sub-D, Reset and Boot signals) and a special software (DwlWinxxx).
Does anybody know where I can get that cable (or find the scheme) and software. It would be really easier for me if other crashes occur in the future.

Thanks,
hal
