Can someone help? My x403p accientally flashed with wrong firmware and it is dead now. I Try the above method, it is not working, not sure if the RS232 port is not correct or not, It is only 3wires in a 4pin connector to DB9 rs232. When I connect to hyperterminal I can see APP init ok but when I try on EROM upgrade, it is not responding at all. Or is there any button I should press to run into programming mode?
Thanks
