I've had a bunch of issues with these machines. Tried to flash new firmware on one unit via SD card slot after incorrectly configuring the static IP once. The reset button does nothing on any of my machines. When i tried to flash the new firmware all that happened was the machine fans started spinning at max RPM and now both the green and red LED remain on. The machine does not pop up on my LAN. Please let me know if you find a way to flash the system or if you've found a way to reset your system.

Additionally try looking through your browser password history to the last good password on the V9 machine you're having issues logging into. It is possible you changed the password and maybe forgot?
