How do I bypass/delete the Activation Lock on my iPod Touch 5th gen?

I tried everything I can. I put in my Apple ID I used to set up that iPod and nada. I tried to look it up but I basically been connecting and disconnecting the WiFi. I need someone to help me get pass it but I cant figure it out. I got it for Christmas back in 2014, and it came in a box and I needed to activate it. So I did and as of Sunday 11/12/2017 I havent been able to bypass it. When I looked up how to bypass it, it mentioned deleting my data I had and I didnt back up my photos that I really wanted to keep. whenever I put in my Apple ID that I used to activate my ipod it says "The Apple ID '(my apple id)' cannot be used to unlock this iPod" and I put the right password for it, but I changed it at one point and I tried BOTH passwords. I really need to activate my ipod again! Anybody that can help will be greatly appreciated! So if anyone knows how PLZ I dont wanna lose everything on my iPod but I also want to activate it again.
