Well, hope bcm4702 survives this... If you've osciloscope you can check this. But as seems it's ok, cause it does not destroys pmon during large firmware upload.

Anyway, if it boots with clear-nvram firmware, then I could make another one with ethernet support...

Be carefull with pin 10 - you can destroy pmon if you attempt to write large firmware, while it's shortened to ground.

Also, after flashing the right firmware - have you tried accessing firmware restoration mode again?
