HP Officejet Pro 8120 - Update required

[Roger1111111]

Hi, my printer does not boot properly. 

After the HP logo a message apprear and the keypad do not work.

Update required

A problem has occurred with one of the printer's critical system files. A printer update will be installed to fix the problem.

What i tried :

• Uninstall the HP driver and do a full reintall via the lastest version.
• Run the HP Scan and print doctor : can't detect the printer
• HP Smart can't detect the printer
• Plug the printer to internet with a cable to my router
• Extract the latest firmware on a USB key in fat32, shutdown the printer, plug the USB key et power up the printer. After the logo, there is a progress bar but after 100% the error message above appear again. I try to find a older build of the firmware without success.
• Try another USB port on my computer
• Remove manually the Windows printer driver to let it detect with no sucess.

Thanks in advance
