i'm assuming you're runnning Windows..
and this is from the back of my memory, i might be wrong..
you should:
1. Get the USB-SerialPort driver, install it somewhere
2. Plug the x0xb0x in the USB of the PC.
3. Switch the x0xb0x ON.
windows should detect a new USB Device, use the USB-SerialPort drivers for it
whenever windows requires a reboot - reboot it..
4. Open your device manager.
whenever you switch the x0xb0x ON - the USB-SerialPort device should show up in there.
once this is working, you have to configure the USB-SerialPort settings, the defaults don't work.
5. Get c0ntr0l, install it run it.
6. Set the Port in control the same as the port you set in the USB-SerialPort settings...
now the actual firmware update:
the USB cable should already be connected, seems there's no reason to remove it at all
1. turn OFF the x0xb0x
2. swith to BOOTLOAD mode
3. turn the x0xb0x ON
4. in c0ntr0l - press Upload Firmware, select the .hex file and watch the status bar
once ready - turn OFF the x0xb0x set the FUNCTION switch to something else, turn-ON.
if this still doesn't help -
