i have a w850i and tried to open it, i am new to this phone thing but i tried, some how i put on a gdfs file and now my phone wont work. when i want to connect the usb cable, the 'c' button i think does nothing. If i press and hold buttons 2-5 it would respond when i connect cable. what can i do? is there a way to get it back?:confused::mad::eek::
