Speedtouch 780WL firmware flash - incompatible?

Hi All,

I've got a 780WL that I'm trying to update the firmware on.

It was ISP locked by KPN so I'm having to go into this via bootp

I can get to the point where I select the firmware it the wizard wont accept it and claims it is incompatible

I've tried all the versions of the firmware I can find for the 780WL (and a few other models on the off chance)

The only thing I can see that seems difference is the device name on my board is reported as Speedtouch while the firmware is for model Speedtouch 780 - though I'm not sure if the wizard would be coded to enforce that or not....

Anyone know if there is a way I can modify the firmware to work with this, get a working firmware version or force the wizard to accept the firmware I am giving it and override its check?

Here is the device details from the wizard:

Device name: SpeedTouch
