ReRooting a Hub

[ptmuldoon]

I have a currently rooted Hub at version 1.1 and I would like to update it to the lastest as the App keeps asking me, but.........

While swapping out my old laptop for a new one I did not realize I did not save a copy of my rsa keys, thus cannot currently SSH back into the Hub.

Do I need to reroot the Hub from scratch in order to regain SSH access? Its been a while since I've had to that, so not sure if the rooting process has changed at all.

Anyone have any suggestions?
