I also tried to get into emergency mode many times by volume up + volume down + Connect USB cable , but i get only LG logo nothing more.

but to use the tool, The device must be in fastboot/bootloader mode.
Now i am not able to get fastboot screen also. i tried number of key combination while powering on phone. but all time i get LG logo nothing else.
Finally rooted my Verizon LG G3 but now I can't get it into recovery mode. When I press the volume up + power button it goes into some download mode and a firmware update screen shows up but it's stuck at 0%. I tried going into recovery mode from quickboot but when the phone restarts, it just says "secure booting error" in small letters in the top left side of the screen and power offs. I think my phone is bricked. Any help would be appreciated

Yeah same thing happen to me as well....
If your phone was bricked, then it wouldn't boot. It just sounds like you can't get to recovery. This typically happens when you attempt to install a custom recovery either the wrong way or on the wrong update for the method. Need more details for further assistance.
What update are you on? Software Version, not just Android version.
What method did you use to root?
Did you try to install a custom recovery? If so, how?
Does it still boot to the OS?
I have tried the power + volume down and plug the usb into the pc and I get to the Modified recovery where you can go into safe mode or factory reset, etc. I have done it before but it was Kingo root that did it. It's not working because I can't get to usb debugging mode. I need to go back to stock. Thanks

If you are using the LGUP method, you do not need to even go into download mode. If you are on the Verizon bootlooped screen you should be able to flash it back to stock right then and there.
Also there is no real recovery method that you can use so you will have to wipe it completely clean unless you have backups.
LGup says phone 'unknown' so it won't work. It worked yesterday. Not sure what happened. Tried the battery pull method but it still doesn't work.

I had the same issue with my VS990. LGUP was not seeing the phone. Using the Recovery menu via power + volume down, I booted my phone into USB debugging mode. LGUP was then able to recognize my phone. I then chose the tot file, chose upgrade instead of refurbished, and clicked start. It auto restarted my phone into Download Mode and started the upgrade. If you can get the phone into USB debugging mode, you'll be set.

Plug a USB cable into your phone with your phone powered off, hold down on the Vol Up button and plug the USB cord into your computer. It should immediately boot into download mode. I have verified this works on my Verizon V10.

I just confirmed that works good job
Huh. I did mine from a regular boot up, but in debug mode. LGUP commanded it to reboot into DL mode for me.
Download mode on the LG V10 is achieved the same way all other recent LG smartphones have been. Power the device off completely by either the power menu or battery pull. Plug your USB cable into your computer. I didn't have an issue with USB 3.0. Hold Volume up and plug in the phone to the computer. Keep holding Volume up until the phone says download mode. It will do a small loading screen then it will change, this is normal. You can leave download mode by pulling out the battery or by holding the power button for 10-15 seconds.

I think you might be doing it wrong...
Download Mode -> Hold volume up, and plug into usb while STILL holding volume up, release once in download mode
Reset Screen -> Hold volume down + power, then plug into usb whil holding down buttons, release when screens comes on.
Ok, now for my problems. I got my phone into DM, used LGUP to install VS99026A_00_0118.kdz on my VS990. I let it go overnight. Came back to see it failed at about 73%, Error "can't get laf property", ever since then I can't get back into DM again, my LG splash screen will come up, then I get the android guy saying "Erasing...", then it reboots to splash screen again, waits a sec, then turns off. I managed to get into the reset screen with vol dn + pwr + usb method, tried to go into safe mode, now I have same issue getting back to that screen too.
Any help?
my lg v10 stops at download mode screen and don't go furhter
I have a V10 stuck in the bootloop. I was able to get it to boot past the lg screen 1 time but it very quickly rebooted again and is still stuck. And when I try download mode using LG Bridge, my computer says "no phone connected" and my phone stays on the "Download Mode" black screen. How can I fix it?

Hello!
My phone got stuck in an boot loop out of nowhere.
I let my phone drain it battery the whole day so today I tried holding the volume down and power button after charging it a bit and I got an fast boot and rescue mode option, I pressed it and now its showing me:
FASTBOOT&RESCUE MODE
Please Connect Usb Cable
Your Computer and Open Hisuite
Android reboot reason:
AP_S_PMU 80
OCP_LDO28
ocp_ldo28
volumnkey_down_press_process_func
What should I do?

I think that means u entered bootloader mode because of pressing the power key and the volume down key. But u said it entered bootloader mode automatically.
After an unsuccessful update, the phone was bricked. It cannot be turned on, but when is connected to the PC, the Qualcomm Port 9008 port become active.
Is it possible to unbrick the phone via Qualcomm EDL mode or any other way?
What? What do you mean it cannot be turned on? Even when breaking a samsung phone's firmware, "download mode" should still be active and working. In that case, you have to reflash a whole firmware again. Unfortunately, there's a chance that you will have to give up on your data.

I actually found a solution. I left the battery on the phone to be completely discharged. Then I pressed 3 buttons (volume (+), volume (-) , and power) and connect the computer via USB cable with the phone. The phone went into an emergency recovery mode. I tried to use Odin, but didn't work out. After pressing the power button (for 5 sec.) The phone restarts and the update started over.
Nevertheless, thank you.

Try entering download mode.
Power off your device.
Press and hold volume up and down buttons at the same time, then connect it to your PC while you still hold them. It will automatically enter download mode.
Flash firmware.
