Unlocking/New ROM Issues

[bmancell]

I am quite new here and at hacking and customizing my phone.

I read all the threads here, how to unlock and flash, but every time I try to do anything, I get the TRICOLOR screen, my phone disconnects from the computer, and the flash or unlock looses connection and nothing worked, gives connection error. I reset my phone and it was how it was before, nothing done.

Whats going on? It's like the phone won't reconnect to the pc once on the TRICOLOR screen.

Ideas, suggestions?
