Re: Re: [OT] Belkin Bluetooth Access Point GPL violation

[Robert Lowery]

Hi Marcel,

At this point, I have not tried pulling the firmware apart, all I have done is telnetted into 
it and poked around a bit.

If I manage to get the kernel source, my next step will be to try and work out how to 
pull apart their firmware and repackage it with a custom kernel.
