I have a LG P999 and I want to flash the baseband however when I go into S/W upgrade mode (Volume down + power button; without battery) my PC does not recognize the phone :(. When its connected and on fully the computer sees it, but not when I hold the volume down button and plug it in. Is there any solution to this? I have also tried holding both volume buttons down installing the APX drivers but that did not work. I have all the drivers for the phone.
