lg g3 ls990 bricked and stucked in download mode - Sprint LG G3

i accidentally flashed the wrong marshmallow firmware in my ls990 and now its bricked.
when I turn on my phone or try to go into recovery or in download mode it turns on and stays on lg logo for sometime and then goes to the firmware update menu.
I tried lg flsh tool and tried to flashed zv4 and zv8 but every time it says (laf read gpt failed)
I also tried the board diag method but ls990 has msm8975 chipset because boarddiag can be done on msm8974..

I've been there and can tell you there is almost nothing on this phone that can't be recovered from. Understand that it will take some time and yes you need to open it up to short the pin but it does indeed work.

And the Problem That I Can not Put the phone into download mode que he ends up appearing this error.
Did you have a custom or a stock recovery in your phone? The way to put L7ii in emergency mode is this:
-Insert the usb cable into pc
-Hold Vol- button
-Insert the cable into your phone while you hold Vol- button and then release it.
Did you try to enter in emergency mode this way?

LG Optimus L7 II(P716) is stuck on LG Logo and doesn't open.

So, My device was rooted(by king root) and i just normally uninstalled one of the software's given with the stock firmware. but after sometime, my phone suddenly restarted. and it was stuck there.
then i tried to reinstall stock firmware using LG Support tool and LG Flash Tool. As i couldn't boot into the phones recovery mode, i had to do these by going into emergency mode. but it still didn't work.
i'm still stuck at the boot screen after flashing something named V20A_VIT.kdz.
So dear brothers please tell me if there's any other ways. i really love this phone.
