Help Needed for Hard Bricked LG F430L ( Gx2 )

Hey Guys..
I have LG F430L ( Gx2 ) and it's in Hard Brick condition, No Download Mode, No Recovery Mode
even phone doesn't Power ON.
And also nothing happens on connecting to PC neither on Ubuntu nor on Windows7.

Means Pure Hard Brick.??

Before this it was shown on Windows in 'QHSUSB' mode and I was able to see Partitions on
Ubuntu. So I tried to copy 'sbl1.img', 'rpm.img', 'tz.img', 'aboot.img' and 'recovery.img'
but when I successfully copied 'sbl1.img' and 'rpm.img' suddenly my home's electricity goes
off and I couldn't copy other three images.
Since then I am facing the above problem..

Please guide me what should I do now.??
