Received my MkV this morning, popped in the sd card, plugged it in with the supplied wall adapter, and all I got was the flashing amber LED, never a blue one. Popped the sd into my laptop, and found nothing but an empty folder named lost+found. Then it got weird. I tried using the recovery web interface, which I was able to connect to no problem, and tried uploading the 1.0.4 upgrade.bin from the downloaded zip, but got an invalid file message; same thing with each version of the downloaded firmware. Then I tried putting the upgrade.bin and md5 files right on the sd card and booting with that in the unit, but got either solid red or continuous blinking yellow led's, depending on the version of the firmware I used. I'm out of ideas at this point. Anyone have any suggestions?
