How do I tame my hamster?

This is not your average new hamster taming session. My brother got this hamster from Pets at home like a month ago. This hamster was like already a month old and lived on his own. Well in that 1month and 2 weeks he played with it and stuff but not much like most days but not for too long. This hamster never got tame cause of this and my bro has been bit a lot. He now wants to rid of this hamster but I saved it and I now look after it. I have had it for about 2 days (its not moved house or cage so its not scared of the new environment) and it is quite difficult. It's like a tiny bit tame. I'll give you some details on it.. I tried putting treats in my hand (this is were my brother got to) but once it eats the treats it stays around my hand and ends up biting me or if I opt to take my hand out while he has like a paw on me he'll hang on and bite. (I make sure I used a different hand to put the treat on the hand that gets bitten so no scent is of food is on it I also washed my hands). If I try to just go in and pick it up I bites me. Once it is picked up tho it is alright, it tries to get out but doesnt go mental. I tried gloves but it reacts the same as if it were a hand. Now I have been bitten a lot I'm scared to play with it as it hurts when I get bit and some times draws blood. It is a female syrian hamster. I assume as she lived on her own she was last of her litter to be bought and so stayed there for a while.

My questions are..

Is it too late to tame it fully its about 2-3 months old.

How do I tame this hamster! My brother and I tried many techniques which one is best! And any tips?!
