Okay, they are not sleeping after all. New firmware update is available now at their website > http://www.nextbookusa.com/download.php, apparently to fix the connection speed. I am downloading the file now, 137mb in size, my serial number not in the list but let have a try first.
Update: Can’t update the firmware to my N7, it said invalid image file. Guess because the serial number not in the list probably.
