Pine64 Boot issues

Hi, I came back home for Christmas and decided to break out my Pine64 (1 GB RAM). I saw this project and downloaded the image:

Unfortuately, I came across two issues:

  1. Pine64 turns off after about 1-2 minutes
  2. No HDMI output

Is there a newer image that solves these problems? Or any configuration that I need to do? Thanks!
