Hard Brick LG G3 "qhsusb_bulk", but not COM port - G3 Q&A, Help & Troubleshooting

Hi guys, my LG G3 is hard-bricked. When I connect it with my PC, in devices there is "qhsusb_bulk", but in ports (COM) there is nothing! Even in disk management PC doesn't recognize it. How can I resolve this problem? Thank you so much!

First install qhsusb_bulk driver after that you can see your g3 port

[Q] Connecting to Windows 7?

Hey guys, sorry for the n00b question.
I plug this phone (my mom's LS-970) into the computer and I can connect as Camera or Media device... how do I just get it to connect as a USB drive?
This is baffling me.
Thanks!
Have you installed the drivers from the LG website?

Shows no phone is connected. Does your pc recognize phone when connected? You have to install QUSB-DLOAD Driver.

LG Flash Tool Won't Recognize Phone :(

I've got an LG G3 by US Cellular (US990) that I'm trying to downgrade using LG Flash Tool. The problem is that it's not being recognized by Flash Tool or by LG PC Suite for some reason. When I plug it in in normal Android it recognizes it whether it be charging, MTP or PTP. But when I go into download mode these programs do not recognize it and so I can't flash anything. Anyone had any similar problems or anything I can try? I have installed the drivers multiple times and I'm on Windows 7 64 bit. Any help or suggestions are greatly appreciated, thanks!

Have you changed the com port yet? If not, set it to 41.
No I haven't, how would I go about doing that?

Help! LGUP Unkown MODEL LG G4

Hey all, I think I broke my G4 h811 , but not at all because I can access to download mode, the problem is that when I try to open LGUP or LG flash tools, my LG appears as UNKNOW MODEL, and because of that I can´t install the kdz file, I tried to re install all the drives and so on, I am working in a win 10 laptop. Someone that can help me. Thanks!!! I will be waiting for a answer.
Enable usb debugging mod in settings>developer options. And also make sure that you have all the lg drivers installed and working. I am sure you will be fine.

Try using LGBridge and clicking the update error recovery.
You are coming from an international rom right?
change port number. or task manager adb kill

So using the hardware buttons, and clicking yes through the factory reset confirmation does not boot you into recovery mode? Did you format your internal memory?

using hardware buttons and clicking yes the phone just restarted and that´s it. I didn´t format my internal memory. I was trying to fix my phone by using kdz files but the problem is that the programs as lg flash tool and LGUP don´t recognize the model of my lg g4.

What firmware were you on? What message did LGBridge say when you tried error update recovery?
I have the same problem with my H815 and Windows 10. All drivers are set up correctly. In device manager, I can see the device and ADB Device, but LGUP won't recognize my G4. Obviously, LGUP is buggy...
Is there any better tooling to upgrade to a more recent ROM? Otherwise, I really would have to change to CM13 - upgrading is very easy and not any nasty USB stuff what in the end may not work at all...

Download this driver. This will help you.
I am new to this forum so I can not link, but you have to look for LG driver version 3.14.1
I had the same problem today and it helped me.
Good luck

Is not I tried another cable and another usb port.. :/
But where you download the flash tool and drivers from?
Unfortunately it is not possible using Windows 10, or USB 3.0. Preferable to use windows 7 and USB 2.0.

For me it never works in Windows 10. To Windows 8.1 works very well. I'll try again with Windows 10, thanks for the info.
I have read the whole thread, and brought my e975 back to life!
I tried a different USB cable and different USB port (2.0 i guess)
Thanks for sharing your experiences!
I just have the win10 pc and I tried another usb and another port and nothing anyone know some fix?
