Don’t bother. As has been stated, the HDD install is broken and you usually end up with a read only partition.
Rest assured it’s being worked on.
Thanks for the heads up ! 
We’d love to get some netcat output from those that run into the system stalling at the end of “installing files”
The cause can be a bunch of things and without netcat there’s no way to see the actual logs since ssh isn’t running at that point.
To use netcat, you need to able to edit the boot configuration on the ext4 partition, have the ATV1 on a wired network connection, and netcat available on another computer
