Skip the reinsert battery part in your item #1:
1) Remove battery
2) Hold Volume plus and minus keys down
3) Insert USB cable while still continuing to hold down those two buttons.
WIthin 1-2 seconds you should have download mode. When download mode appears, then re-insert battery. For sure you're not going into charging mode with no battery to charge. This is the method I always use, and it always works (aside from hard-brick situations, but you can access battery charging mode/graphics, which surely means that ain't you).

not works.

What does your computer say when you plug it in? If in Windows check Device Manager and see what your phone is being recognized as. Can you access the phone's contents via USB cable from your computer? Does ADB recognize it at all? Or does it just loop like that, not starting?
Also, it sometimes takes several tries to get it into download mode, as if you're holding the buttons down and not timed just right, the phone ignore your attempt. Make sure you do not let go of both volume buttons even after you plug in the USB cable, you must continue to hold them down for a couple of seconds (until the DL mode appears). Don't even think about putting the battery back in until you see that download mode box. Try that a few times maybe? If it doesn';t work ,maybe you're boned.

remove battery and place it again. then press both volume+ and Volume - . By keeping pressed both buttons insert your usb cable. don't release pressed buttons until its in download mood. by the way install unified adb driver for android by koush if your using windows 8.1 otherwise lg official driver is ok

Cant enter fastboot ＆ recovery mode！

Hello，everyone,i got a problem that i cant enter fastboot and recovery mode.
today ,i installed CM12 22/7 upgrade ,and before i install this ,i did a backup of build.prop because i have V4A and every time i upgrade CM i have to change this build,prop ,so i want make a copy and when i finish upgrade i can just move that file without do anything ,and everything goes well, i installed upgrade and installed V4A driver ,it says i need restart,so i restarted,but after LG logo ,screen turn black, cant enter system ! i thought maybe i flash CM one more time can repair this,so i press POWER and volume down,but,nothing happen ,after LG logo,and screen turn black,and i try to enter fastboot mode ,its the same ,when LG logo shows screen turn black.......
My phone is LG d855,and my English is bad,i hope you can understand
Can anybody help me?

did you try entering Download mode?

Phone stuck in bootloop, help please
wrong trhead

Are you sure you there is no fastboot and no download mode?
You can enter download mode by pressing and holding the “Volume Up” and connecting the USB cable from phone to PC
If it works then you Soft bricked it...And you can use this guide to fix it:
http://forum.xda-developers.com/showthread.php?t=2785089

BUT if that does not work then you Hard bricked the phone
I had that problem because of flashing with faulty win8 drivers...no download mode or fastboot, all i got was security warning and bootloop. The only way you can fix hardbrick is through JTag, but i don't know if you can fix it without paying someone money, because you need special hardware to do it. You can find people on ebay that can fix it but it will cost you 30-50$.
I sent mine to warranty...they didn't know what was wrong with it and couldn't fix it...and so they just replaced the motherboard. If you have a warranty then send it and do NOT!! tell them you flashed it or rooted it. Tell them you don't know what happened...The chances of them finding out is very small.
If ebay and/or warranty not work, then there was an article on the Internet to fix a hard brick but for some reason it is now password protected...i do not know why....You can send the owner an email so he can give you the password.

But then again you cant be certain this will work either.
Conclusion: Fk LG...They don't want people upgrading their slow buggy software.

i cant enter download mode,always turn black after LG logo

Disconnect cable from pc and phone
Press power + vol -
You will get first black screen, keep pressing until lg logo appears and it shuts off completely.
Then press just vol + and reconnect cable to computer.
That should leave you in download mode or fastboot.

What did you flash, what error does it display, is it "secure boot error", which version of g3 do you have, can you access recovery, do you have TWRP...?

i used ioroot to root the g3 (D855), and i flash with twrp-2.8.0.0_d855-signed.img. Yes i believe it was the secure boot error. After that the notifications lights at the topped flashed blue and red i turn the device ofd to restart and it will not turn on i have tried both to get into the recovery menu (power+vol down) and download menu (power+vol up) neither of which is working.

Ok... Lets start with battery pull in and out.
Even if you do recive secure boot error for booting to the unbumped recovery you should be able to boot to the OS, try with that.
If this fails, do the battery pull again and lets try to get you to the download mode. The way you specified (power+vol down) is incorrect I belive. What you need to do is hold the volume button WITHOUT the power button which will be followed by connecting the device to the PC with installed LG drivers.
If that works you could flash stock files, follow the thread: http://forum.xda-developers.com/showthread.php?t=2785089

Check in device manager how is the phone detected what mode ...

Does it get into download mode? For this one get the battery out and wait 2 secs. Plug it back in. Be sure to have an USB Cable ready plugged in the back of the PC (NOT IN FRONT HUB and be sure to be the original Cable). Hold Volume UP and Plug the cable. Keep holding Volume UP until you see download. Tell me if you see the Firmware Update screen or it is a security error.

LG G8 STUCK IN Qualcomm HS-USM QDLoader 9008

thanks for your reply

What happens if you press&hold VOL- (furing the whole procedure) push the power button until the phone vibrates, release the button und press&hold the power button?

Which ever combination, Vol- + power phone power of
with in sec it boot to Qualcomm mode

I don't know where to ask so I'm gonna try here. My G820N is stuck on Android 10 beta. Whenever I flash an official kdz, it only allows for emergency calls. Can't do anything. Any help would be appreciated

Try entering download mode with phone disconnected from USB cable.
Also try to see if it gets recognized by LG-UP or by LG Bridge. These 2 softwares don't need download mode to be able to flash, just the phone to be recognized on some PORT.
Try also factory reset hard menu. Also try switching between Slot A and Slot B. There is also this backup method. Phone is not dead on one of those slots.
If nothing works (but slot a slot b should 100% work) , wait for the firehose, it's just around the corner. That will restore the phone back 100%.
For more info search v50thinq on telegram app. :good:

I can t get to download as it freezes and without the USB cable it doesn't even try and enter. I appreciate the recommendations. I was thinking of the a/b seit hbut without the use of fastboot I am at a loss of how to switch between the two as I thought the system chose and the switch happened upon rebooting once a system had been selected ie as in turning the unit off after loading the os set a flag to go to the opposite system upon completing the inftframs and boot sequence.

So, if the device, as you say, lost power during an update like that, then almost assuredly you have at least one, if not numerous corrupted partitions.
And, it's specific partitions on the device that allow it to enter download mode. One of these most know about or have heard of is the laf partition. But other have to be there also for it to work, I don't remember exactly what the others off the top of my head, but that info is easily found.
The key thing you need (or any others commenting same prob), is to be able to enter EDL mode and have qfil installed and recognizing the device. If you can get that far, it would be easy to find the correct partitions you could flash with qfil and then immediately go from qfil to download mode.
Many many people have done this. Just get qfil set up (see guides section) and get the device recognized. that takes some effort but it's def doable.

Question phone has bricked itself without seeing a solution

I do not know in depth about all this stuff, I've just been thrown into it because my phone decided to brick itself in a system update after it got into my hands. I updated it and it went into crash dump, a few times, the just nonstop boot looped with the oneplus logo on, and some pixels bugging, then it stopped showing the oneplus logo all together and just boot loops, I can go into fast boot and nothing else, if I restart bootloader it now goes to a charge menu and rarely actually restarts fast boot, I just tried msm and I've tried booting into twrp but it wont work, i believe this is because the phone wont connect to my pc properly but i have tried universal adb drivers, new sdk, and official QUALCOMM ones to all get the same result of appearing in device manager as just andrioud and nothing else with no options for drivers, on msm it would show up but it wouldn't get past waiting for device. also i cant find a proper twrp rom for the 9 pro on here, atleast the stock one, nor can i find it anywhere else, i can only find the img. also i feel I'm missing something with flashing on the fastboot and am not seeing if I'm supposed to be doing something (of the limited things i can do) on the phone, or its all in commands and stuff on here. sorry this is horribly written, I'm tired and stressed because of this.

Search stock rom and download
unzip rom ,connect your phone in download mode and flash STOCK ROM.

You shod download "EDL" tool (even called MSN)
unzip and exetute ad admin (read specifications and troubleshooting in the related thread)
ensure tour phone is off
press and keep both volume buttons while connecting it to PC
then the COM X connection should become "green + connected"
go with "start" and just wait the processo to end

Download mode is not vol up + power, that's bootloader
EDL (Download mode) is both vol buttons + power
It should show up in the device manager on the computer as a Qualcomm device if it's worked correctly.

EDL mode is NOT both Volume buttons + Power, it's just HOLDING BOTH THE VOLUME BUTTONS and WHILE HOLDING THE VOLUME BUTTONS, CONNECT THE USB CABLE. The phone needs to be in a switched OFF state before doing this.
By holding both volume buttons and the power button, you will force restart your phone into bootloader mode (fastboot mode).
And VOLUME UP + POWER BUTTON is recovery mode.
