Thanks for the reply!
I tried out what you said but I had no success with copying the zImage to
the boot partition.
I git cloned the official bearbox repo and tried different tagged releases
and I noticed that the last version that appear to work on my rpi2 is
v2017.03.0 and the versions afterwards appear to be broken (I haven't tried
them all yet but I am guessing none of them work on rpi2)..
