I would first try to get more info on the error codes. The RS6K graphics console does not show error messages, so you need to attach a serial console running 9600 8N1 to the first serial port (Labelled COM1 a la PC)
If using a PC as serial console, use a KNOWN GOOD null modem cable! Let us know. BTW, some people suggest removing the systems's battery for a lenghty period to correct E080. Have not needed to try. Regards RDK
