Thanks for your fast reply,
 
As for the power supply its a 5V 2.5A (the official raspberry one)... The wired thing is I tried different images, (Bananian, Armbian) and the only thing I got running is the precompiled Limaker one...

I just found the problem. I was following the guide on my mac - never had any problems with that so far, all rasbpian flasshing worked fine.... But somehow the flashing of armbian does not work...
 
I did set up parallels and flashed it using linux... everything works now
