Question [Q] Flashed MetrocPCS LG Optimus F6 (LG MS500) with F3 firmware- NOW BRICKED

I accidently flashed a MetrocPCS LG Optimus F6 (LG MS500) with F3 firmware.

Now when i try to turned on the phone the backlight blinks twice and the colours around the home button blinks different colours.

When I try to connect in download mode it does the same thing and then the home button blinks red- it is not recognized by KDZ_FW_UPD.

Master Reset does not work either

PLEASE HELP
