(Mainly to reduce the sub voltage output from 1.8V to 1.0V)
Downloaded the file dp_cfg.txt
Copy this to the SD card
Amp says: Config file bad
Looking at the file with Notepad, it used to be a text file. Now it is this (below). Tried to upload the file, then see "An error occured while reading the configuration file"
Have tried 8 times now. Any idea what is going on?

Yes, as @Delija says. The file starts with a CRC. No one has figured out which CRC Devialet uses so protected config files can't be edited outside of Configurator.
