I have 2 HR10-250s, both with twin upgraded 500GB drives. I decided to try to install PTVNet to get network access. The first worked like a charm. I used the PTVNet download, and I was up and running in a few minutes. The second one was a different story. I'm stuck in a bootup loop. After the "almost there" screen, the unit restarts and goes back to "welcome. powering up." Anyone have any advice?
