first of all... calm down and do not get frusterated with him. Have you talked to him softly and sung to him calmly while he is in his cage? and i would suggest giving him his very favorite treats while he is on your hand... that way he wants to visit you. does he like the spray mists? make sure he does like them, otherwise dont give it to him. Are you quiet and gentle when your around him? he could get startled and hiss at you. it will take time. maybe a lot of time from the sounds of it. but whatever you do, dont give up. leave his cage open and sit near it (not to close) and dont make eye contact with him. predators stare. wait and wait... until he calms down a little. talk to him softly without looking... and maybe he will come out. you could do this every day. good luck.
