If you forgot to use a new device tree or used wrong one and your device doesn't boot:
don't panic!
if booting from SD/USB, simply connect SD/USB to your computer, download a proper device tree, rename it to dtb.img and place on SD/USB
if booting from internal:
Boot this build from SD card or USB with correct device tree.
Login over SSH and execute dd if=/dev/zero of=/dev/dtb bs=256k count=1 then dd if=/flash/dtb.img of=/dev/dtb bs=256k
Power off, remove SD/USB, boot from internal.
