May sound silly, but check to see if you have the remote or sd firmware downloads? .rfu would indicate it being remote. As far as I know, that would be the only reason the firmware would not be detected on the unit (no download screen?)

The C454 is a KM not a Ricoh!!

Make sure the USB stick you are using is 2GB or less & that you copy the files to root of the USB stick. This series is fussy about the type of usb you use unlike the older c552 you could use any!

You're going to have to get a little more detailed...what do you mean by "the correct screen"..If you have the firmware loaded correctly, and the usb drive in the firmware port there are only a few things that can happen

1. MFP boots to firmware screen...You may try ensuring you have the correct machine type selected...choose the correct type, reboot and try the firmware update again.
2. Boot screen reports firmware NG...Wrong firmware for this model
2. MFP boots normally even with USB in firmware port. This indicates that the USB device is corrupt, or there is a file that is preventing the MFP from reading and booting into firmware update mode from the drive. A simple windows format of the USB may not work. Try downloading HPs format tool and run the program on the drive then try the update process again.

Anything else that can be displayed is usually a result of incorrect board replacement, or a problem with the SYS, SSD boards or maybe even a ram issue. The only other thing I can think of without more details, is the possibility that the sensor that sees the update port cover open in disconnected or inop... Emujo

Make sure that you have the firmware for the c454 and not the c454e. They aren't interchangeable. Once you download the right zip file make sure you extract the zip. Now open the extracted folder and then the sub folder with the firmware version number. Select all files and folders within that folder and copy them to the root of your thumb drive. As an extra step you can format the thumb drive in advance. Has to be fat32. Make sure you have plugged the thumb drive into the correct port(covered by a panel. One screw has to be removed to access.). Hope some or all of this helps.
