Pi Zero MMDVM update

[KC7DMF]

Just bought the MMDVM - which is on a Pi-Zero I believe, small enough I don't know what else it could be. Configuration page says
Alert: You are running an outdated version of Pi-Star, please upgrade.
New versions are available from the here: http://www.pistar.uk/downloads/

I don't see anything newer except for the full sized raspberry pi board, so how do I update?
Already ran the upgrade option, and still out of date 3.4.17.

Pi-Star_NanoPi_V3.4.17_09-Jan-2019.zip
Pi-Star_OrangePi_Zero_V3.4.17_09-Jan-2019.zip

All of these aren't actually Pi's ok... confusing name then.
Assumed OrangePi Zero was the Pi Zero, oh well... so much for a name.

So much for that, booted once, restored the config. Now it's dead... no screen, just flashing power light.
Even the original SD won't boot. Somehow the new image must have killed it.
Not what I would call compatible.

I moved the new SD card to a Raspberry pi 4 and it boots just fine. So card is good.
