I'm locked out of galaxy s2

[AC Question]

I have old galaxy s2 (not connected to service but still have wifi and Bluetooth on)and would like to upload my photos but I'mlocked out. I exceeded attempts to use my pattern code and now the device is asking for my google login. I tried my Google login, i even changed my password so see if that would work but i can't gain access. I went to a sprint store and called Samsung, no one can help me do far.
