Re: Full replacement
The suggestion on another thread is that he firmware has been corrupted in a way that prevents it from being replaced. I imagine that this means the firmware has been corrupted to (a) Always allow new code to be installed silently, thus contiuing the intrusion, and (b) silently prevents any further update/downgrade/replacement of the firmware.
It has to be something pretty low level to force a full blown replacement of hardware units.
Instead of Halt and catch fire, this is more halt and be incinerated
