Need CPS and/or firmware for DM-860

Just got a new DM-860 (marked baofeng and looks like a copy of the 1801) from AliExpress. I can’t find CPS software anywhere; or any firmware updates.
I found an 1801 CPS on a web site, but using it corrupted my displays and button functionality and I had to do a factory reset (Fn1+“1”).

Any takers?

Hi, you can find the original firmware/CPS/uploader here https://github.com/acontini/DM-860
Otherwise you can try (at your own risk!) to install the OpenGD1801 via https://github.com/rogerclarkmelbourne/OpenGD77CPS/releases

Cheers,
