MR816-X connexion failure -> dead ?

Yeah, thank you Svenne !

I followed your instructions but it did not work. So I retried with a step more and it worked. So for those who have this problem in the future, the following procedure:

  1. Turn of the device
  2. While keeping the pad button and rotary knob 1 pressed, turn on the device
  3. Wait for the LEDs stops flashing and 3 LEDs light up around the rotary knobs
  4. Still holding the pad button and rotary knob 1 pressed, press the rotary knob 2 and wait the the LEDs stop flashing.

After that, my MR816X works great again !
