bricked my optimus s after root with hard reset, please help....

Have you tried LGNPST? I have the DLL file and TOT file for the Optimus that will restore your phone back to V8.
.
(MAKE SURE YOU DONT HAVE THE NEWER LCD panel if you do it this way) PM if you need help.

Letting you know off the bat i am not the brightest around here, but I did really brick mine pretty bad, and got it working again via LGNPST.
