Are you looking to download firmware on the Mac or change out chips from HP cartridges to aftermarket?

I would like to download the old firmware, or change the chips- whatever will get my printer going again.  Also, everytime someone posts about the old firmware or a solution HP removes the content.  Also, can you Suggest any other sites that are not censored

Hi.  I found the same problem regarding the firmware.  This link may help, although as I mentioned, I didn't need to go that way. 

 
Are you replacing cartridges that are HP?  If so you can do what I did.  I will attach two pictures.  The first is of the HP cartridge (after I removed the chip).  I removed the chip (which was in a slot above where you see the Y).  To do that I used needle nose pliers and broke the small piece of plastic that held the chip in place.  The second picture is of my aftermarket cartridge where I inserted the chip.  There is nothing blocking the slot for the chip, but it does take some fine motor skills.

How did you do this via USB? Did you connect a USB stick direct to the printer? If I do this I can't see a way of seeing the executable file.

 

Or do you have to connect a laptop with the executable firmware file to the printer via a USB cable?

Please check printer model and download corresponding firmware file from https://www.ghost-white-toner.com/firmware-update-warning/ for your model.

Printer driver should be installed on your computer. When you start the .exe file it asks you to select printer to upgrade/ downgrade.

Please keep in mind your printer has to be with Allow Downgrade ENABLED !

Here are short video instructions i found on the net: https://youtu.be/3DxGnet3XLg

Thank you for the quick response!

 

Yes it is most definitely a HP Color LaserJet Pro M254dw.

 

I have done what you said already. When I run the executable file and select the printer, a bar shows that it is supposedly being transferred and a smile emoticon comes up at the end, but like ThierryB68's Post 8, after it has completed:

"I see a 32MB " Firmware Update" print job going into the printer queue, but it stays there and nothing happens on the printer"

This says printer has not received the firmware.

Allow downgrade should be enabled.

Also try changing USB port.
