This uboot image cold bricked my Brume2 from the Beta test period, I will not recommend this upgrade to anyone attempting to, unless it was expected to fail due to small hardware revision changes I'm not aware of.
Fyi, I attended to http://192.168.1.1/uboot.html and uploaded the image, after the reboot prompt no leds went on, and I assume full brick.
atleast gl team could have test this... this posting is almost a week old.
