How do I downgrade my firmware to accept 3rd party inks again?

[Volly4rae]

I have had this printer for 4 years. Warrenty expired. And I have used 3rd party ink forever. I change my ink and suddenly it’s not accepting it. 
   I get an update won’t let me use the ink now, but it’s a big **bleep** move to do it after all this time. I’ve already paid for the ink months ago. Now I’m out 50$ AND the cost of HP ink. 
   I’d love just to get through this cartridge and not have to toss it:/
