i recently did this phone update that my lg notified me about...i put it off for a bit and when i finally did it i could no longer sync my phone to my laptop to get music ( not only do i use it for music but i store all my college papers on it as well for back ups )..a notification would pop up to allow me to go through the process before..but now nothing comes up...there isnt even anything in my phone anylonger for a usb transfer setting...please help
