Failed to check firmware file for persistent parameters.
This error message could pop up due to two reasons.
- If the software prerequisites have not been installed (VC++ redistributables in this case) it will not be possible for the program to load the DFU file.
- If there are any characters other than A-Z a-z 0-9 in the path to the DFU file this error message could also pop up. Try to place the DFU file in a path that does not have any non supported characters.
Failed to set device in configuration mode.
This can happen if the correct DFU driver has not been installed. The program is then unable to connect to the DFU device and will therefore display the error message above. Please follow the guide for Installing STTub30.sys driver to resolve this.
