Approach your partner and head to the right. Aim at the hostages to scare them. After one of your members take the hostages to another room, you will be asked to detonate a bomb. Pull up your mobile phone by pressing Up on the D-Pad, then call the number marked "detonate".
Head to the right, passing a small hallway to your right, look for the opening and continue to the far right for the money, then make your way to the escape point. Once you exit out of the vault, change your character by holding Down on the D-Pad, then Right on the right stick when the guard aims you at gunpoint, after which you can now take down the guard. Simply follow the gang afterwards to escape.
Hide behind the pillars when the cops reach you, then shoot them out one by one. When you head downhill, stay on the road and slowly inch your way through while using the vehicles as cover. The escape vehicle is located after these cars.
Follow the basic driving tutorials and head straight to the pickup point using your radar. Turn right to avoid the roadblock, then ride through the rails to reach the train.
For the shootout, just hide behind the starting cover area and shoot out all the cops that you can until the next cutscene starts.
