Because I am so totally lost by all this. Smile

Why does it not have a fail-safe mechanism to re-install its OS/control image (which is in RAM?) How did they even program it from the factory? And if the software is broken and without such fail-safe mechanism, how is it even possible to repair the software?

I guess I am mentally blocked from following your endeavours as I just cannot get it into my mind that this should be a problem in the first place...

I am probably missing something here.
