I see, so there is no way to install on old NAND?
I'm trying on a MXQ Pro+ and seems to have more success but boot hangs. I'll investigte further.
Another question, is there a way to get accelerated video on 4.18?
I'm using a Beelink mini MX-III, a mini M8S and a MXQPro+, the first two are 905 while the last is 905w. I have tried both xenial, bionic and debian stretch, the debian is the one that seems to work best.
