About 18 months ago i pulled them back out and ran XFCE on one of them. It crashed with the X11 error (i kid you not): "event arrived before it was sent (your hardware is too slow!)" (going from memory - it might have been phrased differently). i ended up giving them away to someone who wanted to use one for a pihole server, and i was glad to be rid of them. Utter garbage, they were.
The referenced Kickstart was for the first pine64 boards, not the phones or laptops:

They were marketed as being "high performance" for both Linux and Android. They weren't, plain and simple. They were next to useless for anything.
