That makes sense, but how would an attacker flash an older version of the firmware in the first place? Don't you need developer options and unlocking + debugging enabled?

Open the case and pogo pin on a flash programmer directly to the pins of the flash chip.
Sophisticated actors (think state-level actors like a border agent who insists on taking your phone to a back room for "inspection" while you wait at customs) can and will develop specialized tooling to help them do this very quickly.
