[HOW TO][VS985][UNBRICK] Hardbrick Guide Using Test Point - Verizon LG G3

So I recently bricked my G3 and it was a living hell to unbrick it from the lack of info but I gathered what I could and did it. My G3 is working great now so here's how I did it: (for the record I had no download mode, no recovery, and no system for flashing JasminROM after flashing a 35B bootstack...so don't do that.)
Required Materials:
Bricked G3
Screwdriver
Wire
USB Cable of good quality
PC
Solder (Optional)
Soldering Iron (Optional)
Things required on PC:
Secureboot disabled and test mode enable
Qualcomm USB Drivers (attached)
TOT File
Zip file containing willcracker's tools (attached)

Have drivers installed and tot file ready. Also make sure battery is removed and top cover is removed to expose motherboard.
Steps:
1. Plug in USB cable to PC
2. Connect one end of the wire to ground (or solder it to the ground point as it is much easier to simply hold one wire end)
3. Connect other wire end to the second point from the bottom (see pic)
4. Plug in the USB cable to phone (should hear windows tone for connection within seconds)
5. Release second wire end
6. Check device manager for device, should be Qualcomm 9008 (jot down port #)
7. Open the zip
8. Extract contents to desktop
9. Run Board Diag as admin
10. Select downloaded tot file under Image Extraction (BIN section)
11. Choose an output folder (any folder) we'll call this Folder O
12. Click Extract
13. Choose B2 from first drop menu
14. Choose the correct com port from second drop menu
15. Choose Folder O for Target Dir
16. Check AP CHECK and EMMC Test
17. Hit Start
18. Restore Device should now have drop menu, select aboot and hit start
19. Do the same for: BackupGPT, boot, dbi, laf, PrimaryGPT, recovery, rpm, tz and finally sbl1 (MAKE SURE THIS IS THE LAST ONE FLASHED)
20. Phone should get disconnected
21. Put battery in
22. Power On
23. Flash the complete KDZ using LGFlashTool for a completely clean install. Make sure software versions match.
Credits to @willcracker for files and guide, I just rewrote it and made it much more clear (test point was in the posts under thread and weren't well explained). If you have questions, feel free to ask.

Hey i did this thing for all img... Including system userdata and cache... Now its still the same... When i switch it on it shows lg logo and goes to "Demigod Crash Handler"...... Help please........

---

I got through step 19, but now I get the LG logo with "Boot Failure" under it and it's stuck in a boot loop. Any idea what I did wrong?
ETA: I was able to get into the Firmware Update mode and use the LG Flash Tool. Thanks for this guide.

Question, after updating from OTA 47a mine started rebooting continually. After trying several options I did a factory reset which took several hours to actually get it done. I set it back up and when signing into a second Gmail account it rebooted again. Did another reset. I got into safe mode, deleted apps like google maps, Gmail, tv, books, etc. Then let It sit over night. It shut off. Now it would only load up to the LG screen or Verizon screen and then shut off. But it seems to get worse cause now I have to pull the battery and sometimes for several minutes. (phone worked perfectly before these updates and never rooted)
I tried to use LG Flash Tool but the phone won't stay in download mode long enough. Sometimes 20 seconds sometimes 5.
So my question is what are my options short of sending it to LG or using as a paper weight.

Sadly, I don't know what else to suggest. *If* you had been able to get it to stay in Download mode long enough, I would flash the 10B TOT. TOTs flash more things than KDZs, so sometimes flashing a TOT will solve a problem when flashing a KDZ doesn't (I've personally had that experience). Flashing KDZs after flashing the TOT is fine.
If there's some way to force it to go into QHSUSB_BULK 9008 mode (I haven't looked at the first post in a while, so maybe that's what they're referring to), then there's a third option, which you'd have to Google that term to find the recovery directions using different drivers and a different program. It would show up as QHSUSB_BULK 9008 in Windows' Device Manager - I believe in the Ports section, but possibly in the Modem section.
On the upside, I had the absolute best experience with LG for a repair, but that was my tablet under warranty - no idea if the experience differs if you're out of warranty.

I'm having this exact issue. Any luck fixing the issue?

After going back and forth with verizon I got down to 2 options. Send to LG and pay for repairs or take Verizon's offer of early upgrade on device payments. I got that offer thru chat. I told the girl if she wasn't tech support to let me know how to get one. She said she was so I told her to let me explain everything first. Then she said short of sending it to LG I did everything. So then she gave me that offer.
I'm not happy about it but had to do something.
I got the LG G5 and like it but hate it. This only seems to charge to 90% over night then stops charging. I have only got it to charge to 100% maybe 4 times total in the 11 days I have had it.

Forcing it into download mode is basically the whole guide.

It just pops right with a flat head or a pry tool.

When I extract the tot with BoardDiag, everything goes swimmingly, but when I try to start eh AP check and EMMC test, it says "There is no partition file (rawprogram0.xml)."
Any clue as to how to fix it?

Can you verify if where BoardDiag extracted the partitions from the TOT that the "rawprogram0.xml" files actually does exist or doesn't? It creates some partition file (can't recall if that's the correct name) when it extracts the TOT. I assume that's the same name as the one it creates.

By saying that you had no download mode, did you mean that the screen was black when you attempted to go into download mode? Or did you mean that you tried using the LG Flash Tool with no success? I was in the same situation as you were (flashing Jasmine Rom on the 35b bootstrap and getting a black screen even when the device was powered on) and I didn't want to unscrew the phone to get into the motherboard. Luckily, I was able to unbrick using the "downgrade to 10b method" by @LASERWOLF452 which I will link. So I attempted to get into the download mode, but the screen was black. However, my phone was recognized as the "LGE Mobile For VZW" in the device manager. From here, I was able to follow the downgrade guide, and while the screen stayed black for the entire process, the display miraculously showed the LG logo at the "waiting for reset" part of the flash tool at around 85%. Then everything went as usual, with me only having to do the battery pull when the screen displayed "factory reset status 3". Upon turning the phone back on, it booted normally into the setup wizard. However, the flash tool took a very long time to finish up, taking 1277 seconds instead of the usual 150-180 second time.
Tl;dr: Tried putting your LG G3 into download mode only to get a screen that shows absolutely nothing? If your device is properly recognized by your device manager as "LGE Mobile For VZW", then your download mode should still be working and you can follow the steps for the downgrade method to get your phone back up and running.
