So my batch 2 unit wouldn't work out of the box. The display was showing the IP as 127.0.0.1. After a bit of messing around, I figured the SD card was to blame and that a reflash was in order.
To anyone else that gets this, you can clear it by simply pressing and holding the reset button [on the LCD].
That didn't work in my case, I attempted that twice. Absolutely had to reflash the SD card.
