FAILED (remote: dtb not found)
finished. total time: 0.385s

Trying flashing the kernel over fastboot results in a short vibro and no other sign of life...
Exactly the same thing with scorpion_windy aka SGP611.

Also interesting, that the kernel compiled with the same sources but with the Z3 leo defconfigs boots up, and even enters into recovery, with no LCD as expected on a slyghtly different hardware. And there is no warning trying hotbooting it over fastboot.

Might suppose that there is an issue with device tree for scorpion models.

how are you compiling? i have tested and the kernel builds and boots fine
the windy devices use the same config as the GSM models
