The mba gets loaded with .b00 for some reason, not even the .mdt.

And at least on this device the .mbn doesn't work at all either, but this 
might be due to very weird firmware loading on this board - because also for 
loading wcnss firmware I needed to add a quite weird hack to make it load.

Modem fortunately loads fine like this.
