Hello,
for people who complain there is not enough progress, I have some good and some bad news. I made some progress reading/writing data (including logos, audio recordings, voice and Chinese font) in Linux, and created something similar to md380-dfu. Plus I made a converter to make it possible to convert logo graphics to png and back. The results are in
But for the recordings, you will also need a patched variant of dsd to decode the recording files, see README.md in the repository.
If you wish to, you may try them, they should work both with python 2 and 3, run the scripts without parameters to show help.
But the bad news is, I am not able to work with the codeplug, just back it up and restore later, not use the .data files. Plus the description is very basic, for Linux users with experience. I left for holiday, so I probably won’t be able to change it for a week or so.
