Did you change the device tree? I got stuck at the Vorke logo when I used a wrong device tree. The latest beta device tree for S912 3gb 1000Mps is wrong (see my post further up from 25 October).
I used the following device tree from 6/18/2018 at the link below.
Edit: wrxtasy can you confirm which are the correct device trees for boxes with S912 3GB mem and 1GBit Lan?
