FYI I have a code plug available for the Anytone 868 DMR radio (older model) using (I believe) the latest 868 firmware 2.36. If there is any interest I would be happy to post it here.
It's basically the same as the 878 code plug - no operational difference (same channels, zones and talk groups).
I currently have an 868 so for the foreseeable future I will be updating this code plug when I revise the 878 one.
