GX440 radio fw failed flashing red signal & yellow network

I was updating the radio FW on the device, it rebooted and the power light is green, the network light is flashing yellow at a rate of 1 per second, the signal light is flashing red at a rate of one flash per 2 seconds. Unable to access the device using the UI and PuTTY. I just received the unit back from Sierra getting repaired. Any ideas?
