i have just been given an lg 3d and was told it was not working, i left on charge and it started to show signs of life! i had it running and all was well until i wanted to upgrade the software as per instuction from the lg site. the phone will no longer switch on and after much time and hair pulling it showed the battery symbol and was charging again. I left it to finish but now it fails to start!!!!! any advice please.
download the xda-developers app or go to xda-developers.com, go to forums and search for optimus 3D General and Optimus 3D Android development. search for some threads on how to flash .bin or .kdz files. you'll be up in no time after you get the omapp drivers setup; these phones are UN breakable and you have signs of life which means its fixable. good luck
