Once that is added close Configuration and open "Software Download" from the start menu<li>Click "Backup" on the utility and choose where to save the "QCN" File
It says could not connect? Have checked under my computer but the drive for the phone is not showing?
Any advice would be appreciated
I'm no expert on this only having done it a week ago on my own phone but for this stage you have to open the correct port with the QPST Configuration tool. The Software Download application uses this opened port to download the QCN file. Without this file you are going to have to jump through some additional hoops to get your Wifi to work once you flash your rom. You shouldn't run the unlock tool until you are sure you have the QCN file saved somewhere on your hard drive and that it is not 0kb in size (mine was around 300kb in size I think). Once you have done the unlock procedure you re-upload this file to the phone to reconfigure your wifi or something to that effect.
