[Q] E970 Bootloop not getting fixed by LGNPST topic

Folks -

I am noob here but believe me I did every thing to search existing thread and get solution to my problem.

Okay so here is my problem: My LG E970 is stuck in boot loop. Phone starts and it stays on for about 30-45 seconds and then again it restarts. This loop continues.

1. I tried Safemode and the problem still exists.
2. I tried to flash stock ROM with LGNPST by going through download mode and still issue exists.
3. I tried Tinybeen "E970_Original_TeenyBin-AA.bin" with LGNPST and still no solution to problem.

I am also not able to fast boot i.e. when I press volume up + power on then only LG logo keeps on flashing.

Please help me what I am missing. I thought flashing stock ROM should solve all the problem.

Thanks in advance for all your help.
