I'm attempting to root my revue. I bought the following usb-ttl cable. http://www.rovingnetworks.com/files/res ... -PRO3V.pdf. The problem comes when I plug the usb connector from the converter into my laptop. The hdmi output on the revue turns off. I have to unplug the usb-ttl and reboot the revue to bring it back. I also tried connecting to the revue using putty after the video died and could not get a connection. Help Please!!
