But strange why this other operator has problems installing the firmware.
Perhaps some older version of hardware with incompatible bootloader
That’s weird, it should work. Even the official TYT releases are exactly the same for both radios (well, actually they don’t post any firmware files for the UV390, you have to contact them or find out by yourself that the ones for the UV380 work).
Problem may be some difference in the loader on some radios
The loader is failing when it uses the Set Configuation command in the driver. I don't know what this command does.
The command is
STDFU_SelectCurrentConfiguration(ref hDevice, 0, 0, 0)
i.e confirguation 0,0,0
Possibly some older UV390 radios require that a different configuation number is used
Or possibly there is some conflict with the harware on the PC
I also tested my radio with the Official STM DFUSe loader from STMicro, who make the CPU chip, and their loader detects the radio
