Just want to know if it is able to be repaired. It was in the middle of updating Firmware, when my computer froze. I seem to recall the printer was showing "reflashing" and got to 4 of 5. I stupidly switched everything off. And now the printer switches on to this error code and won't do anything. Include switching off. I have receycled router, printer and laptop several times following the HP support instructions. No change.
