FUS_STATE_IMG_NOT_AUTHENTIC error updating FUS from 0.5.3 on STM32WB55

[MVanam]

I'm trying to upgrade the FUS and wireless stack version on my STM32WB55 Nucleo board via ST-LINK using STM32CUBE Programmer GUI tool and seeing this error message FUS_STATE_IMG_NOT_AUTHENTIC. I'm using "STM32WB5x\stm32wb5x_FUS_fw.bin" to upgrade the FUS version. 

Any suggestions to resolve this issue?

Hello,

In order to update the FUS from v0.5.3 on STM32WB55, you should use this binary stm32wb5x_FUS_fw_for_fus_0_5_3.bin. You can look this wiki page which describes how to update the wireless firmware.
