So far we find out that three different versions / revisions of Beelink X2 exists. All three are confirmed to work, the one I have, work.

Just give some moments, the screen does not come up strait since boot loader that we use, does not have video driver.

sorry i just realized i didn't follow the topic.
 
i want to confirm that with the lastest Armbian_5.20_Beelinkx2_Debian_jessie_3.4.112.img, it seems to have fixed my boot issues as well.
 
I only have used it for a day but did many shutdown / upgrades / reboots and haven't seen the "purple no boot" behavior that i had previously.
 
I do have some reboot / shutdown "problems" :
got a faulty reboot (shutdown -r now) with it stuck on purple but power cycling solved it.
got a weird halt (shutdown -h now) with no red light on (no led), and others with red light but that i couldn't start from the power button or remote, but i don't know if it's possible or not.
 
Also it's probably not relevant, as i stepped on the wires during first boot, but the sd card resize did not work, i will try again.
