I just got my STM32WB55 Nucleo boards with FUS v.0.5.3 and trying to upgrade firmware but neither of the provided .bin files in "repository" ("stm32wb5x_FUS_fw.bin" or "stm32wb5x_FUS_fw_for_fus_0_5_3.bin") work. I get the same message for both when trying to program the files using STM32CubeProgrammer tool. (Note: message "Firmware Delete Successful" was present).
Attaching a picture of the error message I get.
Note: I tried to accomplish the same thing using both user USB DFU and ST-LINK interfaces.
Here's log from my flash attempts:
