[Q] FAILED (remote: dtb not found) topic

OK so I was trying to root my LG R smartwatch.
(I have been following this thread

I have been able to UNLOCK my bootloader, as I have a nice unlocked padlock when I boot the device, but it stays in fastboot mode now.

When I try to
START \ RECOVERY MODE \ RESTART BOOTLOADER
it just loops right back to the FASTBOOT MENU

I have tried fastoot oem unlock and I get
FAILED (remote: Already Unlocked)
Finished. . . . . total time 0.329s

But if I try
fastboot boot LGGW-rootboot.img
I get

downloading 'boot.img'...
OKAY [ 0.344s]
booting...
FAILED (remote: dtb not found)
finished. total time: 0.418s


Help please, I have a bricked watch and my lady is going mental as it was a birthday present and I have only had it a week :)


[EDIT]
LG G WATCH TOOL
Under any option I get.....
I'm now getting
WAITING FOR DEVICE

Using gohma-gwatch-2-3
WAITING FOR DEVICE

I have tried to put the device into FIRMWARE UPDATE MODE and it just sits there waiting to be updated, but I cant seem to get the firmware over.
