Copy from /tmp/remote.conf (working box) to /storage/.config/remote.conf .
Thanks kszaq, I actually just made a new sd card install from scratch, ran it on the working box, then booted it on the faulty box, Installtointernal and presto.
The whole thing took about 9 mins. Should have just done that from the start. I did start trying to create/edit the remote.conf file... Yeah that is a long process... Worth doing if you have no other option, but I did, so I was glad to avoid that.
Thanks for the location of the remote.conf file on the working box.
