Turns out they sent the wrong power supply. It's 12V and 0.5amps, when back of the unit says 12V, 2.5 amps!
I couldn’t find a perfectly matching power supply, but did find one that’s 12V and 3.0 amps for now.
So I got into recovery mode and flashed with the latest firmware. However, it's asking me for the Admin password. Is there a default I should use?
I also tried installing via the app but it's still asking me for a login I don't have. I did a Google search and it says use admin but that doesn't work.
EDIT: Turns out after flashing the firmware I had to reset it again. Then was able to configure it and up and running!
