So I am completely stumped.. I would like to perform this guide to unlock my bootloader on my LG g8 thinq the only problem i continuously run into is when i put my phone into EDL mode and connect it to my PC I check the device manager and it comes up as qusb_bulk_cid:xxx_SN:xxxxxxx I have tried everything i can think of to fix this issue... I have installed all of the latest qualcomm drivers, ADB drivers, USB drivers and nothing will correct this for QFIL to be able to pick up my phone and a port that gets assigned to it like (COM1) ect ect. I really hope someone could tell me what im doing wrong and or what im missing please. I everyone else get this qualcomm 9008 thing instead and I cant for the life of me figure out what is going on.

Haven't done this part in quite a while, but I think you just need to right click it in file manager, oops I mean device manager of course, and assign the appropriate driver to it.

I have attempted to do this and every time I do it says windows could not install the driver. I’ve also used a driver updating software and it said the driver was missing. Tried to update/install it and it did nothing.. just kept saying the driver was missing.

Hi all,
I'm getting crazy and tired about this KS20.
I tried everything on this mobile but nothing worked and now emergency mode is only mode I can turn on the thing: not even the hard reset works anymore (booting stucks on vodafone logo).
Corona drivers never worked: reading inf file they are for product ID 6061, but my mobile when connected is product ID 6000 and only LGE usb drivers (downloaded thru the LG update agent) are correctly working.
And LGMDP can see the device but not flash procedure can be initialized on it.
Someone could help me with that please?????
Come guys!
Give me suggestions please!
Hello,
Your message is somewhat confusing that we can help you, otherwise there is already post on this type of problem you should first browse the forum looking for info more precise. The first goal is the flash in emergency mode, after everything is possible ...

I searched the forum and googled everything but nothing related to that.
As I wrote in my first post I could not install Corona drivers because, weird enough, device is not recognized by them. I had to install LGE usb drivers thru LG Agent update wizard.
So I can not flash thru LMPD.
Thanks for your reply anyway.
What OS do you use? Do you have administrator rights!
I do have administrator rights.
I do confirm anyway that only LGE USB drivers (they are directly from LG, Product ID 6000) are working fine when in emergency mode.... but they are not Corona drivers (ones signed for Product ID 6061) and LDMP is not working because of that.
Do I have a chance to install rom if I'm not using Corona drivers?
No !
What OS do you use?
Windows xp sp2
I can imagine that none had to deal with this firmware version.
I guess I had to throw away this mobile... such a wate!
Thanks anyway.

Try to gain access to a computer with Windows 7 or Vista, the work better with Corona drivers.
Install the drivers first, restart just to play safe, connect your phone in emergency mode (make sure the green LED is on) and wait for driver detection and installation to finish. If the second driver takes too long to install, then just disconnect the phone and reconnect again. Flash in emergency mode as usual.
In case you have lost your IMEI, use the IMEI restoration tool to generate a new .nv2 file.
Keep updating us on how things work out for you.
If you haven't seen it already, try and have a look at this guide: http://forum.xda-developers.com/showthread.php?t=548447
The part about disabling and enabling the LG driver in Device Manager got my computer to recognize the device in emergency mode so I could flash rickou26's newest ROM on there (and by the way, thanks for the ROM, rickou )
Thanks guys ... i will try your suggestions as soon as I'll be at home again (next week)!

I tried the guide last week but it didn't work for me.
I guess this V08h firmware (not seen anywhere on the web) is a lost cause!
I'm wondering, when going through the different boot modes, bootloader and recovery, there is a third option that shows up on the pc called Moorefield. It's an unknown driver, which leads me to believe there is some sort diagnostic functionality to it. I guess it's just a matter of figuring out what drivers work. I was wondering if anyone has had this experience, and/or knows how to work with it.
Moorefield is the name for intel processor. It will come handy when all other option to recover phone are not working. But for that we need drivers and image file to jumpstart.

I have spent litterally all day trying to update my mrs g3 d855 and i have had no luck, how much of it because my computer i dont know. Im running a chromebook with a full linux distro gallumos installed, got virtual box running 32 bit windows 7. Android sdk, adb etc and got lg drivers installed to recognise the device in its various states, ptp, mtp, download. all that is working. got the official lg mobile support tool and the lg 2014 flash tool.
the problem im having is neither of these will update the phone, if i try to manaully flash the kdz using the flashtool or updating using the official one, it wont update recover either. if i try different region or enter the imei number it always fails at 4%. Iv tried different usb cables, different ports, the phone was at 100% battery the whole time, the laptop was on charge the whole time. I really dont know what else to do, i have no access to another windows machine here and its the mrs phone and she wouldnt want me to take it to work to try on another pc there. As i said earlier the drivers all seem installed correctly, the firmware downloads and extracts as it should but I really am at the point i dont know what else to try
Hello,
Did you try LGUP method? Link is here.
It's easy to use. All you need is there, try it and reply
Just TIP: Do you really have correct drivers for download mode? If LGUP see you device as "unknown", change your COM port to #41
Do "FULL WIPE AND INSTALL MM"
I think I might of, how ever before work I did download a version of lg up and some kind of other installer for it. I also got a kdz file to try and flash. The drivers should all be fine, it gets recognised in all the various modes. My fiance is on nights this week, the soonest il be able to try again is tomorrow so I will let you know it goes. Thank you for replying

Thanks buddy il let you know after I can try it again. If it was a Nexus it would be fine, I know all about fastboot, unlocking bootloaders and rooting and stuff for the Nexus line. So much easier to work with
So I think I might know where I'm going wrong, i thought I had all the drivers set up but there's one I missed, for download mode
Under device manager I see when the phone is turned on with adb on
Android device- lge mobile adb interface-google Inc 4.0.0.0-working properly
Portable devices-g3-lg electronics 4.0.0.0-working properly
Ports (com & lot)-lg mobile USB serial port (com 4)-lg electronics 4.0.0.0-working properly
In download mode device manager
android device isn't there, no adb which is fair enough
Portable devices-g3 with yellow warning triangle-lg electronics 4.0.0.0- the device cannot start code 10
Ports (com & lot)-lg mobile USB serial port (com 4)-lg electronics 4.0.0.0-working properly
So I need to trouble shoot why the device cannot start. I have downloaded 2 packs of Lg drivers, lg united mobile driver & lg mobile driver. Both of which contain loads of drivers inside.
If I guide windows into either of the folders it won't install any new drivers giving an error saying that the driver software is already up to date.
I'm going to Google to find out what's going on with device cannot start error, if I'm missing something obvious please jump in
Can you please post complete screenshot with windows device manager (with open ports menu) and adb console with command "adb devices" ?
In your chromebook, do you have disabled all USB power saving bull****s? Also check VM software to see if there is such a possibility to enable/disable USB power plans.
At least, sorry for my bad english Still a lot of things to learn.
Your English is fine I understand perfectly, in fact I wouldn't of guessed it's not your native language so don't worry! Iv taken photos of my screen. You will see when the phone is turned on normally the host and client can both see the device and adb shows the device is detected and returns the serial number, all good there. The last photos shows when it's in download mode and that the driver isn't working properly, it can not start the device with a code 10 error. If I can fix that I know the lgup programming will run. The problem is because the PC can't communicate with the PC in download mode because of some driver issue.
I'm going to have to carry on tomorrow as I have to go to work and the Mrs needs her phone here while she sleeps

Please, enter download mode and change in Windows COM port from #3 to #41 and try LGUP method . It's up to you what method (upgrade, full wipe) you choose.
OK sounds straight forward enough. As I say il have to try tomorrow as I'm at work now and left the Mrs with her phone at home asleep, she will be working night shift so it will have to be when she is back home. I really appreciate the help and il post again to update how I get on
Where I am now is no further, iv tried changing the port to 41 through device manager. Iv set the port 0041 in virtual box for USB settings. Iv tried several sets of drivers. What keeps happening no matter which set of drivers I use when the phone goes into download mode mtp stops working and stops the phone communicating with the PC. When I restart it will work normally for a while but go wrong again. If I try lg up and starting the upgrade in download mode it gives me an error saying it can't change to download mode if I choose refurbish or upgrade. Lg PC suite just hangs at 0% and returns an error after a while. The 2014 flash tool will get as far as trying to flash but hangs at 4% and returns an error but doesn't specify what. I really don't know what else I can do. When these programs reboot the device into download mode it disconnects the device from the virtual machine and I can't get it connected again quick enough before errors are returned or mtp stops working which requires me to reboot the VM or phone. The only thing I can think to do is try on another machine. If it was my phone I would of thrown it out the window or under a bus. Lg software is unusable through virtual machines and I am not buying a new PC just for this lol Il see if I can use someone else's. I hate being defeated, iv have spent probably some 16 hours and got no where! Why can't they just release an ota? It only strengthens my belief in nexus and fastboot. Sorry for the rant but this really has got under my skin and I don't like giving in
Edit
I'm just as annoyed with windows as lg at this point. I really don't like using it. Grrrr

If you want helpful responses you have to be more specific. Assuming you have the fastboot files installed on your PC/laptop ... What LG G4 model? What software version? Bootloader Unlocked? etc.
Assuming you have installed on your PC/laptop LGMobileDriver_WHQL_Ver_4.2.0 available for download from the LG US site as the Windows driver can create issues, have you tried downloading and installing the "Official" TWRP app and installing that way?
Suggest if you are still having problems, you head over to: https://forum.xda-developers.com/g4/development/recovery-twrp-3-touch-recovery-t3442424

I have the right files, when I get into adb reboot into bootloader
it no longer recognizes the device. I cannot flash twrp
After reboot into bootloader, open your "windows device manager" and see if windows detects your device properly.

Don't allow Windows 10 to update your drivers - you can set that up in Windows. Google it for the how-to.

The device type changes depending on "how" its connected. Windows can "see" it as a ADB device, MODEM, etc...
With the phone connected, uninstall all device related on windows device manager, refresh the device manager for it to detect the phone as it should be (as you need it to be detected).
Sometimes its needed a manual device driver install. Happens some times to me, unfortunately I don't remember exactly how I do it because the issues (when it happens) are kind of random, so, I need to "understand" what is going wrong and fix it.
Just to tell you that is nothing unfixable on the procedure, you just need to have patience and find out how windows is supposed to detect your device.
If you don't find out by yourself, tomorrow (Monday), I'll try to see on mine how it should be detected in fastboot mode and tell you. Today its already late for me...
Good luck

Your device should be seen as "LGE Android Phone" (if your lg drivers are good).
Now gonna be tricky because my OS is in Portuguese, I don''t know exactly the path name in English... use your imagination
Connect the device on a USB 2 Port !!!
In windows device manager, select "update driver", "search software on the computer", "allow to choose from a list of avalable drivers". unmark the "compatible hardware" and find on the list the needed drivers. If the "LGE" drivers don't work, try to download Universal ADB Drivers, maybe it works.

I'm thinking it could be a corrupted LG driver. Download another from the LG US site, ONLY. Uninstall the one you have installed now, reboot and install the newly downloaded one. Then connect your phone and see if it is recognized and shown correctly in Windows Device Manager. Also, in adb type lsusb and see if the phone is listed in the output.

Hello. I might of read and tried the directions a thousand times and yet no results. My phone never shows up on msm download tool and when it does, I get the param preload error. I don't know w hat drivers I need. I don't know what drivers are already there and how I am supposed to proceed. I am very frustrated.
Forget it I figured it out. I never let go of volume up and down and when I plugged it back into the PC and it decided to stay in edl mode the whole time. Plus uninstalling the USB drivers that came with them helped. The qualcomm drivers helped but only when downloaded in edl mode. Somehow did the l2 64 bit drivers thing. And voila. Official usb cable was used and it was attached to the usb ports on the motherboard.
