Hi, I have a hamster that was given to me by another family and at first he was sweet and love to be held. Its been about two months since I got him, and he is continuously trying to bite me even when my hand isn't in the cage. I have tried everything I could think of, plus everything in properly handling a hamster. I was wondering if you can please help me with more advice.

Whenever there is a drastic change in behavior, an underlying medical problem needs to be ruled out before you can just assume it is a behavioral issue. I suggest you get Cookie to a vet for an exam to make sure there is nothing medically wrong with her that is causing the issue. Use a vet that is used to treating hamsters like this one: ( https://vcahospitals.com/alameda-east/specialty/services/exotic-animal-medicine ) Hope this helps. Best wishes.
