flashing over serial port

[bleros]

usb to serial plugs into a usb port...

10 pin header is for jtag. Serial connections have to be made(solder) on the modem board.

Whatever usb/serial cable you choose should come with the correct driver and that will actually be another port in device manger. I bought a Nokia ca-42 phone cable and cut the phone end off as it has a prolific serial chip in it. Google that if your interested.

You will need to connect the ethernet cable and use putty or hyper terminal to flash the modem.

Thanks you. so i dont need to connect nothing inside modem. for flashing , modem canot be flashed with ethernet.
