disabled iphone 5

I have an old iPhone5 we have not used in years. I charged it up and tried to remember the passcode. I failed enough times that I am not locked out. I tried resetting it with iTunes, but without the passcode it won't connect to the computer. I tried using the Find My iPhone App, but the wifi password has been changed multiple times since last connected with this phone, so although it is listed, it cant be reset that way. I dont need it to work as a phone or even access the internet beyond downloading the music I have on iTunes. Can anyone help me? I am the only and original owner of this phone.
