If you never had the chance to see the internals of one USB 3G modem , today is you lucky day.

Looks like true nano electronics to me, not serviceable by humans.
It is dead, some sort of boot loader corruption, that no one are able to handle, speaking about repairing it.
It does not detected by any computer, because it does not boot as USB device any more, even if it gets power and the LED turns on in five seconds after connecting it.
Just enjoy the pictures.
And yes it is double - triple tested that it is damaged!!
