I have opened the case de-soldered the antenna and soldered a header to J7.

Pin outs from the top (nearest to the power button)

TX
RX
GROUND
Vcc (Not usually required)

Find attached

1) Default conf.bin (this has been renamed to conf.zip)

2) Broadcom Bootstrap Serial Output (serial output recieved whilst pressing the reset button during boot of modem)

3) Normal Serial Output during boot.


Edit: Just tried restoring default conf.bin and in the GUI I received an error "Error code: 4501

You put a wrong file."

EDIT /3/16 Corrected my pin outs

ejs:
If you can login to the shell using the serial connection, it would be useful to dump the mtdblock where the config is saved and copy it off the device somehow. You might need to change some setting in the web UI and save the config first.

I have recently (this morning) found the key needed to decrypt the default_config.xml and reduced_data_model.xml files, although they will probably not be particularly useful anyway.

Yes tried that and it then worked.

Not possible at the moment, my keystrokes are sending incorrectly via the serial link; if I press a "s" the terminal receives "sJ" or similar.

Not sure if it is my soldering or something else, (I'm no expert)

Dray:
Maybe reduce the serial link speed

Thanks Dray...will try that in the next couple of days.
