*IF YOU HAVEN'T ACTUALLY DONE IT THEN PLEASE DO NOT ANSWER*

I have SETool V1.08, I have loaded it up, held C on the fone and connected the USB cable. I have got the phones GDFS file and then nothing....totally stuck and am on the verge of just binning the phone and doing without one. Any ideas from people in the business? Simple directions please as the one I have printed out is 3 pages of technically madness.....thanks
