I had bricked my LG OPTIMUS T P509 earlier and was stuck in a never ending loop of LG boot. Eventually realized i had a bricked phone. Decided to play around and found KDZ Updater. After much research and googleing i found the kdz file for the LG OPTIMUS P509 and was able to flash the phone back to Stock again. It will recovery in Android Recovery 3E and you just do a battery pull and it will boot again. Will take awhile to boot up but after it does your phone is back with everything stock. Strangely nothing was erased keeping all my apps intact. Only downfall, root was lost.
