This shit happened to me recently. Installed firmware update and immediately my 3rd party toner stops working. Try to find old firmware to roll back to and couldn’t locate it anywhere. Found some for other models via Google drive links in Reddit posts, but nothing for my printer.
I replaced the toner with new 3rd party toner which worked. And now I’ll never install another firmware update on the printer and should probably block it from the internet.

Even with a backup, there are chance they put a “security feature” to prevent downgrade.
