Nice finding. Just some comments:
- Mosfet is a standard NPN Transistor (mmbt3904lt1). Just in case anybody wants to re-assemble later.
- Instead of removing complete Transistor (red), as alternatives:
- lifiting one leg (green) -or-
- removing the Resistor (orange) -or-
- short-circuit the two contacts (yellow) -or-
- move the Resistor from (orange) to (yellow) position (technically most clean way)
will have the same effect.
