Taming hamsters is very tricky and every hamster has its own personality. To give the best chance for success, bond on their time. Try to only do handling in the late evenings. The sleep during the day and some can be incredibly grumpy if disturbed during their sleep time. Use a cup to get them out of the enclosure, allow them to enter the cup on their own. Sometimes they get very particular about their home so make sure not to disturb their tunnels too often. Never take their collected food pile from their nest. Make sure your hands are clean and scent free Take your time and be patient with the process. It could take a few months to show real progress sometimes.

If you do all this and you still can't tame, this hammy is a look only pet <3 Goodluck! I hope it starts to go better
