Hi I got a T-Mobile Black SE T630 from a matrix site but I won't to get all the T-Mobile stuff of it. I have heard about the 13 sec trick but also heard that it can **** up your phone so I don't want to risk it. I also heard of flashing the phone but I don't know how to do it, what I need etc so if anyone knows how I can do this can you please post or if you know any other way to remove it all and get everything to the way it should be on a normal unbranded T630/

Thanks
