Non HP Chip Detected. How to Downgrade your HP 7740 Printer firmware through usb with the .ful file.

Thanks a lot!

Brillian!! Can you share the .ful file for hp officejet po 9010??

Hi, I tried this but it didn't work. My HP is an 8702 and I didn't see that one in the downloads. I used the one for 8710, -15 or -18. Should I have used the other? is there not one for me? I unzipped it and put it on the USB and plugged it into the printer but didn't get the option to download it. It just showed the regular USB options like scanning.
My issue is even more frustrating than your example. I have REAL HP cartridges that are brand new but older- possibly expired. But I know the ink is in there! I also followed instructions I found elsewhere to go back to factory settings. It seemed to be working but made no change on my error message. I DID put into practice your tip on not letting it automatically upgrade so I'm thankful for that.

Leider kann ich trotz ausgeschaltetem Wifi nicht über den USB das downgrade aufspielen. Habe nun alles probiert, auch aufspielen über cmd. Bei HP steht nun auch geschrieben, dass am Drucker per USB keine manuellen Updates mehr aufgespielt werden können. Ist das ein neuer Clou seit dem letzten Update?

thanks alot

Hi. How can I do if my computer is under Ubuntu and not windows ?

Did you know, that after 4 years HP makes it almost impossible to use your printer|? The software forces your to renew the software every time you want to print. My HP deskjet is a goner, no more HP for me. Who knows if HP will rig software to prevent their ink tank printers from using non-HP ink.

HP nothing!! They going overboard now...

any link for 8610 firmware? thanks

Your video's are so very helpful! I scoured through your HP Pro Jet Files in order to downgrade the Firmware on an HP Printer but was unable to find one for my HP Pro Jet 9010. At one point I see it WAS available at the this video was posted but as of today10/19/23 I don't see it through the MEGA file links you've kindly shared. Any chance you'll be adding it back to the MEGA file drive? I'm in desperate need!!😱🥴🥺

Works fine! HP created the problem but offers no solution, but you did, thanks! This saved the printer.

Hi! I have an HP Officejet 6950 printer. I use the original pantron, but I refill it. I think the printer has disabled the cartridge because it detects it as empty. Do you think this update will solve that? Can the ink level be cleared? Thx

I don't see a downgrade specific to the 8025e. Will the 8210 work?

Brilliant! Well done, good sir. I am not the most tech savvy, but I was able to easily follow your instructions and successfully printing again. Hooray!

Hello, I need older firmware for HP 9012e, I would be very grateful for your help
