Straight up want to say massive thanks for this. Second time I’ve had to do this - but forgot how I did it the first time. Perseverance with the holding down is the key. Respect for doing that test in the face of seemingly endless loops, Dominik! (FIY, I ended up with a dead looking android character, and the ‘no command’ prompt … but as Dominik said, the loop was broken, and plugging into the charger let it once again start up as normal)
