I’ve just tried updating manually to the latest nightly (Lakka-imx6.arm-devel-20160303085716-r21349-g1212325) and after installation and rebooting the screen goes black, nothing happens and the device is inaccessible. I had to reflash, copy all my stuff to the SD and try again.This time with the SSH update (lakka-update) - same thing happened again 
Is there maybe something wrong with the latest version? Did anyone else have the same problem, maybe?
To me it seems it’s not even booting though - there’s no “red light” on my Cubox - there seems to be an issue already at that stage - but I’ll check.
