My new OBI100 keeps downgrading its firmware from build 2719, which is the latest, to 2711. I have successfully updated the firmware several different ways and every time the device reboots itself after a few minutes and downgrades to the prior build, 2711.
Just in case someone else runs into this I will update this posting. Oddly enough, after multiple attempts to update my OBI and hours after trying, it out of the blue updated itself after I ended a lengthy phone call.
