No, there are other solutions, you can revert to the old software with the service tool.
Is there a service specialist working at Lexmark?

Please can someone who understands write, everyone write must change the toner, there are those who have a solution, the firmware is not normally downgraded, there is only a return to the old version with the service tool.

i gave you the solution. lexmark along with many other manufacturers have set their equipment to give you such message with a product that didn't come from them is installed. it has to help protect against issues from using a defective product. even if you find a work around for the toner to work. it is generally going to cause issues in the long run and cost you more money that if you had just purchased the lexmark product in the beginning. not trying to rain on your parade, just trying to give ya the best option to save ya in the long run.
