HP ENVY 4500 ERROR CODE OX83COOOOA NOS_LOADER_APP

[MSchu]

Bought the HP ENVY 4500 All-in-one about 2 or 3 years ago, but never opened the box. Yesteday I attempted to set it up. Upon powering up I got the ERROR CODE OX83C0000A NOS_LOADER_APP message on the printer screen. I have tried all the unplugging, waiting, repowering. Not using a power strip or extension cord. Power button flashes and error code are the only signsof life. Software has been installed but my computer does not recognize it. I tried the pushing a bunch of buttons at the same time (as someone suggested). Once I got REFLASH 12345. Otherwise back to ERROR CODE. Help...about ready to get violent.
