Brume Uboot

Hi, I have been using the Brume over the weekend, now I would like to install the Ubuntu image, reading in the Brume documents “You may also try other firmwares such as DDWRT.
Note: If you uploaded an incompatible firmware thus bricked the router, please use Uboot to re-install the correct firmware.”
Going over the Uboot Docs the Brume is not listed, does the Brume support Uboot?

read below…

Brume does use u-boot, and need to check/update as per above (your Brume might already be ok, but you need to check it)
