My Olive 6HD has a problem. When I turn it on, it stops at the white "Olive" screen. A couple of times, it goes past that screen and then displays a message saying "404-not found". I contacted Olive and they advised me to do the USB stick recovery. Fortunately, I do have things backed up. I followed all the USB recoveryl tnstructions but, when I get the message on my Olive saying "insert USB stick" and do so, nothing happens. I've tried re-inserting in several times and leaving it in for an hour or more but it's not working. I would appreciate any suggestions.
