OXC19a003 and downgrade firmware on HP photosmart plus B210a


Hi. I do an upgrade on firmware of my HP Photosmart plus B210a and install a new HP original cartridge (black). But the printer doesn’t work. It appear Oxc19a0003 error. I clean the contacts of heads. Restart it (un plug and plug etc). I think the better option is try to downgrade firmware but i can’t acces printer menu (it is blocked beacause of the error). There is any way to do it from the pc/mac and connected via USB to the printer?
