HP Recommended
Product: HP LaserJet Pro MFP M428dw

I have 2 identical printers (MFP M428dw). I use generic toners for both of them and it's been working great. I accidentally updated the firmware on one of them and now it refuses to print unless I buy HP branded toner, which I don't want to do. The printer that has firmware version 2149A works perfectly, but the printer that has been updated to 2208A blocks printing due to "Dynamic Security". I can't find the 2149A firmware anywhere. How do I proceed?
