What changes were you trying to make to the programme. Is it just to disable the dust alert?
It is a little vague what you are describing.
I dont understand why you can't turn off the camera? Switch it off and switch on again and follow the instructions exactly as you have on those pages you quoted.

Hi sakineh,

Probably too late, but it sounds like you have activated the sensor cleaning mode where the mirror flips up and the shutter opens to give you access to the sensor. Turn the camera off, the on again. You should hear the shutter close and the mirror flip down. Everything should be fine, but you might have to recharge your battery again.

I guess I shouldn't bother responding to some threads because they just disappear. Wasn't there one of these in another forum? Or This one? Very annoying.
