So yesterday, i was flying my Tello indoors, no problems there, but my dad came and tried to do the thing that you put the palm beneath the sensors, and it went up, but as soon as he removed the hand, one of the motors stopped, i think this could be a firmware issue that overvolted one of the motors. Now, this isnt a ask for repair post, as there is a local repair center, just share your thoughts on what you think happened.
