Forgotten Passcode
I have an old iPhone 6 that I want to use at the beach for my apple music. Its' been years since I've used this phone and I've forgotten the passcode. I've tried a hard reset, but iTunes won't let me restore the phone because it says the device can't be found. How can I erase the passcode and get into the phone? I don't care if I erase the phone. (I also have no idea which computer I used to update through iTunes in the past).
