I have this LG G3, and it switched off and wont boot up again.

Only sometimes will it boot and show the lg logo for about 10 minutes before going into fastboot and tried to erase through fastboot but cannot. I want to fix it and have tried a number of methods but with no breakthrough. How can I unbrick it?

hi everyone, please help me to fix this lg g3
the problem is, my device has detected in device manager as qualcomm hs usb 9008
from the boarddiag, it show that my ap test, emmc, and sdram pass or in good condition
i have using boarddiag to flash aboot,primarygpt, laf etc,
the problem is after flash that thing, i still can't enter download mode, even i press vol up while insert usb cable to pc, my device still don't enter download mode, just LG logo and black screen and turn to qualcomm hs usb 9008 again, why ???
for information,
before this brick i use marshmallow, or i must use the laf of marshmallow again? because i use laf kitkat rom, 10e, if that so can you share laf.mbn from marshmallow v30b? i have laf.img from 30b but the problem i can't enter the fastboot mode to flash it

If your phone is furbished, you have to confirm your. Model by opening and looking at the board.
You are flashing 855 firmware but that might be any other model.

Hey everyone
My LG G4 (H815) suddenly turned off when i was using it, and it showed no life when i tried to boot it up again. Its completely stock, no custom recovery or custom firmware is installed. I cant boot into fastboot or EDL mode. I tried the button combinations as well as the test point method but i just cant get it to enter any kind of recovery mode, the screen just remains black (no backlight either). I installed the Qualcomm HS-USB drivers and when i plug my phone in my pc it gets recognized by QFIL. I tried flashing the fimware but it always gives me the Sahara unable to read packet header error. Can anyone help me?
Thanks in advance.
