WLC 3504 Will Not Boot

[theathletic]

Bought a new Cisco 3504 WLC.

I've connected a USB cable to the console port and accessed the console via the terminal on my Mac:

screen /dev/tty.usbmodem1461 9600 

I then restart the 3504 and all I get in the terminal is "Cisco bootloader . . ." - I try to hit escape and stop the booting, but nothing happens. I've had the machine on for 24 hours now and booting never finishes. I've also done both versions of reset (hold button for 3 second and hold button for 10 seconds) and I all I get is the same "Cisco bootloader . . ." message.

Note: I have also tried using the service port but never get an IP. This led me to believe the machine was not booting. 

The System light is slow green flashing and the Alert light is solid amber.

You should open a TAC case. Might be a faulty unit.

In my case is very similar the issue.
