It is not possible to load firmware onto these radios using normal DFU tools Daniel F1RMB has written a Python based loader to support installing the firmware from a Linux computer https://opengd77.com/downloads/CPS/Latest/Linux_loader_for_STM32_radios Note.

It looks like the connections to the Flash chip are on the same pins as the UV380 etc
