Firmware upgrade blocking aftermarket toner cartridges

[Stormonite]

My MFP M281cdw Laserjet printer no longer recognizes aftermarket toner cartridges.  I can only assume that is because the printer automatically installed a firmware update that renders the printer useless without HP cartridges.  I found a Youtube video showing how to download and install firmware version 20200612 to correct the problem but that video is 3 years old (long before Windows 11) and I think Windows 11 won't install it because it doesn't recognize the .RFU file extension.  How can HP keep doing this?!?!?  I'm beyond frustrated and angry.  What is my solution - go back to HP cartridges or switch brands and never buy HP anything again?  I hope it doesn't come to that !!

Can you share a link to that youtube video you are reffering, I doubt they youtuber managed to send RFU to that printer model.

RFU that printer model doesn't support RFU.

Do you have an old firmware version?

Are you able to help me download firmware that will allow me to use my aftermarket cartridges?

Thank you!

The video is good, it's not RFU file but doesn't matter. 

Do you have an older firmware version on your computer and did you try to run the update as on the video?

I looked for the file in the same place the video showed to look but it's not there.  Where should it be?  If it's not there, can you direct me to where to download it or send me the one I need?  Thanks!

What is the status on this?

I have not received a response to my question about how I can get access to my printer functions again.
