De branding a W890i

Unfortunately, I've come unstuck again. I've got those files and A2 Uploader 5 and I'm following the tutorial. I click Flash and hold 2+5 and insert the USB end but the message in A2 is still 'Hold C and insert USB cable' does that just stay there while it does its stuff or is some other message supposed to come up to confirm you've done it properly? I stopped it and tried it with C as well but the message is still there.

When I do put the USB in I have to select Phone Mode, USB Mode etc on my phone... perhaps I have to select a particular one?

Ok I've figured it out. Just for the sake of anyone else reading this in my position... make sure you turn your phone off before inserting the USB cable!
