malfunction after install firmware

[Guy142]

after I installed a new toner cartridge, which is not an original from HP, I was asked to install a new firmware.

Shortly after went the printer in the error and shows rd in the display despite several attempts to reset the printer even with HP-Support, nothing changed about the error. Although I have put back the original cartridge in the mean time.
