Updating Firmware

My D850 currently has firmware version C1.10 with a XQD memory card slot. I want to update to C1.31 so that I can use CFexpress B memory cards as the XQD format is becoming obsolete. I have purchased my CFexpress B card reader and a Lexar 256GB Silver card which I have successfully formatted in my computer, and I have downloaded the D850_0131.bin file and copied it to the Lexar card, following all th instructions in the Nikon Download Centaur. When I insert the card into my D850 I just get a Err message in the top screen, and there is no "Update" option in the Firmware Version inn the setup menu
What have I done wrong?

Trying to understand here. You must update firmware to use CFExpress? And you are putting the firmware file on that new CFExpress card to write the new firmware (which is required to allow the card to be ready)?

The card carrying the bin file must be formatted in the camera then follow the instructions - paying attention to the update files must be in the main directory of the card not in a folder

If I were in your position you want to use the SD card formatted in camera (or your older XQD card formatted) the card used should not have anything on it but the firmware

This should solve the error message (also make sure your battery has plenty of charge)
