hey i got a couple of guestions for you guys. well i am planning on de-branding my sony ericsson w580i. and i was just wondering when i took out my memory stick and sim card my phone says put sim card back in and i am un able to do anything on the phone. also when i did hold "c" on the phone and put in the usb cord nothing happens but a sound on my desktop saying its in. but when i hit flash it shows the green bar going left too right. but in the left upper window there is no progress being printed up for me to see what it is changing. what am i doing wrong?

thanks guys.
