1. connect your phone in emergency mode to the windows pc.
2. check the device manage, to see if there any lg hardware there, don't run the lg update tool now, and you should previously install the lg driver first
3. if you see the 3 lg hardwares, disable the modem one, i found this one make the connection dosen't work when run the lg update tool in emergency mode.
4. just run the lg update tool, it will detect you phone and update itself, even it stop at 4%, if you get luck, you can wait it finish or disconnect the phone, your fastboot should be back.


My Phone LG Optimus P713 / LG L7 , I tried to follow the advice that you give but still stuck at 15% and Handphone back dead again, I repeated many times the result is the same whether there are other ways that might work 100%. please help I've felt bored and tired thinking about it. :(
