LCD firmware update problem

Hello, I tried to update the firmware of the LCD following the wiki procedure.
I only disconnected the USB cable on the LCD, I did not touch the other connector.

Now my screen shows only white squares and the files on the SD card have not been renamed.
I reflected the official firmware and I still have the same problem.

Can anyone help me ?

    Hi @Ryo , welcome!

    Please check the FAQ page. This question is answered there.

    FYI - there are three connectors plugged into the LCD. The 8-pin LCD data cable, the two pin "B1" filament sensor cable, and the USB cable.

    If you still have problems, then I would suggest try to format the card and try again - or try a different card. Don't forget to copy all the resources, including the main firmware file, the config file, and the image resource folder.

    No you need to copy the files on a SD card and put that in the port on the display board you likely have to open the printer for this.
