I got the same 'stuck on 1s problem' followed by the prompt saying the software update failed.

So I'm following jayford's advice in post #8 but I get the prompt getting stuck with this message: "Suitable USB device not found, waiting"

I have pressed the 'u' key and see the nokia logo with the USB sign on the top right while doing this. I've tried different usb ports also.

I'm using windows vista 32bit...
