What could be wrong with my 18Fet infineon KH618 controller. I have been succesfully flashed it with xpd-ebike program many times. Now I tried the original chinese programming software, cause I read it was more solid. The programming went fine but I accidentally turned to throttle regen on. Now when I try to flash the controller I can't succesfully do it. Any of these programming softwares won't flash or even read. I tried new USB-TTL adapter but without luck. Also it halts now on high speed regen. Any help?
