That means that the demo models did not remove the 3g modem card from its socket. That is good news for demo owners.
It also means that you should be able to install a normal firmware image (plus the kernel image, if needed), using the serial port with ymodem protocol. See the "seaniko7 unbricking" youtube video (linked in the Dev Corner master index sticky) to see how to do this.
