The original firmware of your printer cannot be downgraded to earlier version. Please, follow the instructions below. The firmware, which you need to use: https://inkchip.net/download/INKCHIP.net_Firmware_2022June_WF5790_v1.rar Algorithm for solving the problem: 1) Check and memorize current firmware version of your printer. 2) Start installing the firmware in the Firmware Mode (by pressing a certain button combinations) 3) When the firmware installation reaches 100% you need to disconnect the power cable from your printer. Wait for about 10 seconds and then plug the cable in. A message will appear on your printer screen, saying that the printer is in Recovery Mode. 4) Start installing the Inkchip firmware again, wait for the firmware to load, your printer will shut down. Turn your printer on. 5) Check your printer's firmware version. It must be different. This means that the process was successful. 6) Now you need to use the Activation Program from our website and activate it with the key. After the activation you have to reboot your printer.
