Hey I have a 7210 I also have the DKU-5 data cable Im not sure how or why but after uploading a few mids on to my phone it went a bit crazy (I was using the nokia cable and software)and after a quick restart to try to sort it out it just sits displaying "contact service" after 5 min of reading I have come to to conclusion that the software/bios is buggered and needs flashed.

My question here is how much would it be to get the cables and flash it myself or how much would nokia charge.

or is the phone gone?
