you should be able to get into service via trouble reset hold utility button while turning on copier when you get to trouble reset screen do the stop 0 stop 0 1 and that should get you in. You might need to put the stock firmware on to cure the fault. If you need anymore help i can look into it for you.

Your memory (NAVram) is full, you need to clear it.

DID you swap a board from a different machine if so you really messed up the machine, Have a tech come out to look it over mite run below? NVRAM holds the serial number and counts so people cant erase the counts as new.
