I'm seeking the HEX file for the HTRC B6 V2 charger, but Google Uncle isn't helping; the charger can't read the file. It's hex because it's encrypted; at the very least, I can't read it. The message "device is protected" appeared on my screen.
Procku STM8S207R8T6 is the charger. I attempted to contact HT-RC but was unsuccessful.
