OK so it works, and that's what I've always thought.
But what's the real advantage of doing it, then ???
Is that true, that quiet mode is available and rip-lock is disactivated ? Something else ??
BTW, if I was about to flash my 109 with A09, I think I would do it with DVRUpdate from initial_D, in order to avoid *** ANY *** hex edit of the firmware as you suggest....
