Sony Ericsson

I'm new here...can someone provide some support on debranding my SE 810i. I have gone through many of the threads to educate myself, but I still am having trouble. I have a credit with wotan. Once I connect the USB cable to my phone while holding the "C" button nothing happens except....My phone goes into file transfer mode. or my photos get uploading on my computer. The Wotan program never seems to connect with my phone.

The "C" button is the one right below the cingular internet icon correct???

I asked for support on wotan but I've got no answer.

If you have successfully completed debranding can you please help me!
