A couple days back I bricked my G3 so I tried many things but nothing seemed to work, then I found R-T-B's guide, and it worked, it can unbrick any G3 Vs985.
I highly suggest you to read the complete guide before proceeding and you must ignore the instructions.txt file included in the Unbrick Kit folder.
I am just writing this, the tools are from @R-T-B
Say thanks to that guy and if you like please donate.

What is Hard Brick?
When your has no power, no sign of life, no indication whether plugged or not, sometimes vibrates when plugged in usually stays at black screen aka dead, LED changes color.
To Put Your Phone in Qualcomm USB mode:
If connected to PC Device Manager recognizes as LGE Android Mobile Usb which isn't a good sign means you going to have to Short Pin via test point.
Open your phone and take out the battery. Remove the top half of the phone housing. You do not need to remove the bottom half by the usb. Also you don't need to remove the screw next to the camera. If you do remember that it is a different size so keep it separate.
2. You will see a big metal shield. You need to remove it. It is pretty easy just pry it off and it pops back into place when you are done.
3. Next you need to short the pins as shown in the following picture with a small thin, stiff metal wire. While continuing to short the pins plug in your usb cable. You should hear windows detect the phone almost instantly. Keep shorting the pins for the count to 5 and then you can release the wire. See image below, ignore the ethernet connector.
Shorting means just attaching those two points with a small thin, stiff metal wire for 5secs or so.
4. Now open device manager in windows and it should show your phone under com ports as Qualcomm 9008 (COM #). If it doesn't try the process over again. When it does work remember this number. It is going to be used later.
5. When your phone has detected as Qualcomm usb then release the shorting points.
Now you're ready for resurrection of your beloved LG G3
Pre-requisites:
All you need is in this Unbrick Kit, it's a pretty big file, download, be patient.
Download it here:
md5:
c2a9cff174ed0d4a1c218023087d10cc
Qualcomm QDLoader_HS-USB_Driver 32 and 64bit
LG_Verizon_Drivers
LGUnitedMobileDriver
Note: Only install 32bit or 64bit drivers of Qualcomm, don't install both
Procedure:
Make sure your phone is in Qualcomm 9008 mode note the com port # in Device Manager
If you are on a 64 bit system you will need to disable driver signing. Here is how:
Step 1. Open the Windows command prompt as "Run as Administrator".
Step 2. Run
Code:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
Step 3. To finalize the process run
Code:
bcdedit -set TESTSIGNING ON
Or you can simply disable driver signing by pressing F8 before Windows logo appear when it's booting.
Step 4. Reboot and you're done.
Connect your phone w/o battery and run BoardDiag from folder "v2.99" inc. in Unbrick kit
And be sure the AP check and EMMC are checked, select AP chipset as B2 (MSM8974AC), check Qualcomm's port # from Device Manager and put it in BoardDiag's ComPort box, see image below:
Now click start and wait for test to complete, if that does not work, try unchecking the EMMC test. If that still does not work, use the BoardDiag in v3.99c folder and also try it without EMMC test.
If it throws an error about not being in dload mode you need to restart the shorting process. Hold the short for a bit longer this time.
Now check RESTORE BOOT IMG and choose "aboot" from drop down menu and again click start
Do the same for following partitions FOLLOW THE ORDER!!
BackupGPT
boot
dbi
laf
PrimaryGPT
recovery
rpm
tz
Now flash "sbl1". Always flash "sbl1" at the end to prevent super brick.
Phone should now get disconnected.
Remember your phone is connected w/o battery till this point.
Now disconnect from PC and put in the battery
Hold Volume Up button and connect to PC while holding Volume Up button, Congrats you're in download mode. Now use LG Flash Tool 2014 included in Unbrick Kit.
Run it As Administrator, see image below.
You'll see this window after clicking CSE Flash, hit enter.
Now it will Stop Responding at 99 percent, happened to me, so I assume it's just a bug in the program. Don't worry it's still going to install the software in your LG G3
Do not remove usb/unplug phone till your phone restarts.
NOTES: If you get an error about a dll missing you need to download and install the following: Download
Now your running 47A Android MM :P
Hope that this helps, also if you find any problems or need help please post so I can update this post.
Feel free to comment and help me to improve this guide.
