You shouldn´t reset the phone, select "it´s slightly better", keep the phone active all the time and don´t smash it. Then, you must touch her, leave the phone in the bedroom, select "Do whatever i can to help her", ask if you are her owner and let her study something interesting.
In this point you need to work expanding her territory and show your "personal folder" to her and then tell everything to Si-Won, give Mal0 a show, let her as she is, work on manipulation of real objects, give Mal0 what she wants, let Mal0 do the BJ and accept the offer of Si-Won. Afterward you need to demand answers to Professor Zellen before do what she asks, then tell Mal0 keep blocking the data and release Mal0; she will kill the GTA and break the relation with Si-Won. Finally you decide go to talk with Professor Zellen and you unlock the scene.
It´s the same method to get the 69 scene, except you go talk with Zellen at the end.
