Jailbreak Unregisterable Kindle

Hi everyone,

I have an original 2012 paperwhite which I'd like to jailbreak to help with university study, but its not registered. It also has updated firmware. As the kindle only connects to 3g infrastructure, which is no longer available in my region, I can't register it. This puts me out of all available options for jailbreaking as far as I've been able to research. Could someone help me out here?
