I already downloaded the firm wire 4.0.0 and use tiny umbrella and press the shift tab. It says error 3002. ive try it a million times and it wont work. it starts extracting firm wire but then the error come up. I think is my phone or my computer. does it have something to do that i'm using windows XP. Can someone help me. i want to downgrade and i'm currently using version 4.0.2.
