this midday I was worrying about this semi-bricked FR, so I came back to home to do some extra checks. I put my efforts on the small resistor that has to be changed (the vertical one on the bottom left): - I Tried to measure it directly onboard : 0 ohm -> seems to be dead. - I shorten it, then tested with a "recorder" app. I could hear my voice ! So It can be a way to check this one. The "shorten" resistor cause the recorded sound to be really loud, so I'll put a small resistor (2k) inplace. Hope this can help other people : some other cases have been reported by Bearstech (France). Thank you all for your quicks answers ! My friend will get back its FR fully fixed! P.S. : I didn't remove the 1024Fix while performing those actions.
