Do u use a USB2.0 port?
I know this question might be stupid, but I noticed that if I need to do put my G 975 or my 2X P990 into fastboot I need to use a USB2.0 port to get proper community between my computer and phone, dunno if this is ur problem too.

If u have any Android device driver installed uninstall it, and install the official google one for adb/fastboot and see if that helps.

i assume you are still able to charge your phone? do you have a custom rom installed? reinstall latest proper drivers. i would try a factory reset or a hard reset. if that does not work it may be a hardware issue.

any way to convert a stock kdz to a .bin file, maybe it can resolve my problem?
Nope,no way.
If you have a wireless network home,you can always use airdroid to transfer files to/from phone.

I had this issue, had to RMA it.
Most likely, the device is still covered by manufacturer's waranty, use it!
Have done this and they changed the usb port on the phone but that didnt solve the problem, after, the guy at the cellstore said me that because i have changed the rom they cannot send it again to lg...

Indeed, unless you can go back to stock... Which is kinda hard without USB :|
Anyway to return stock without usb?
do you have 32 or 64bit Windows?
tried another usb port and maybe another cable if you ain't using the stock LG OEM USB cable.
if it don't wanna get detected on your pc try a friends pc or laptop see if that work.
32 & 64, osx , ubuntu all tried with different pc and cable.

that sounds weird then because last time i had this problem it was the cable i used on my own pc it didn't work here, but it did on my dad's laptop.
it was when i found out that the original lg oem usb cable couldn't charge my phone anymore, but data works fine.
I went to a cellphone reparation shop, they tested it and tell me that it must be an hardware or firmware issus with the phone...

What does it say when you plug it into the computer?
QHUSB_BULK?
I guess the better option is to try using LG flash tool to flash kdz, not sure if download mode will be booted since you mentioned download mode failed.
If none really work then should consider restoring stock rom using LG pc suite
Am I correct in saying the phone simply does not boot into download mode? You have have the phone off, hold + or - and plug USB in?

i flash my rom using TWRP recovery
thank you xda users
asking for help
Hello!
I would like to ask you, that can you maybe help me with my LG G3 (D855) (16GB). I live in Europa, Hungary
I bought the device as used, and i would have liked to download the latest software via wifi, then on the phone restarted, and was only the TWRP on the phone, i restarted the device again, but i could entry only in the TWRP. I downloaded a ROM from the XDA, and i made a mistake, i installed the D851 software. The phone is bricked, no download mode. I tryed to unbrick, but every method need the download mode. If i put the device on the PC, the PC see only as modem. LGE AnroidNet USB modem, and the the port name LGE AnroidNet USB Serial Port Com4. If the battery is low, i see on the display, that show that need to charge, but nothing more life signal. If you can help me with some information and with files or via teamviewer, i will glad for you, and also donate. i think i have the correct TOT file, and the DLL file.
LGD855AT-00-V10k-234-30-VUK-SEP-03-2014-16G+0.tot
LGD855_20140526_LGFLASHv160.dll
I downloaded a program "BoardDiag3.99c.zip". but this program ask the BIN file, i found another program b2b.exe, that ask the TOT file at the extraction. Maybe that's is same?
As i wrote the PC sees my phone only as modem, and LGE AnroidNet USB Serial Port Com4. I dont know what is "Qualcomm HS-USB QDLoader 9008 mode", i dont see in the port menu. I hope that You, or someone can help me. i downloaded the QDLoader HS-USB Driver, but again show only the "LGE AnroidNet USB Serial Port Com4" (or now this is com41, i wanted to try a method, but need the download mode) Sorry for the bad english.
Have a nice day!
i have the same issue

Already tried, with battery in it boots and crashes, when plugged in without battery it just connects and disconnects over and over.
Have tried multiple cords, usb 2.0 & 3.0 ports. Same story.
Installed mediatek driver, uninstalled; you name it I tried it with the exception of opening it. Haven't got to that stage yet, I'm lazy.

if adb cant be able to be able to connect and stay connected ( bootloop or restarting problems )
then take SP Tool flasher to flash the Scatter MT6582 from stock KK by only remove battery first and let it out.
plug the universal usb port on cable but on the end of the cellphone dont plug it yet...
in SP Tool check the checkboxe in settings to checksum DL DA. and select usb high speed and W/O battery options.
then when the scatter is loaded then you ready to flash. the latest SF Tool is recommanded.
click on Download on SP tool when done the steps. it will hang on idle but at this moment press de volume down button first.
keeps holding that button until the end of flashing process and when hold it now plug the cable to your computer and bam you will be able to flash it to stock or custom your desire 320 without problems and its will not disconnect during process since you holding the volume down button.
that's how I did resolve my problem about months and find my own solution.
hope this helps... dont be shy to let me know if it worked for you or if you still need assitance.
have a nice day.
peace.

After searching and searching, seems someone actually had the same problem as I do. But for my part even when pressing the volume down before connecting to the computer doesn't keep the phone from connecting and disconnecting, even tried all the buttons combination you can imagine.
I'm wondering if it could be a driver issue, in your case was your device disconnecting every 5 seconds? And do you have any special driver that I should be aware of, personally I have Preloader USB VCOM port version 2.0.0.0...
I hope you got something in mind, I don't know where to look anymore haha.
Thanks again
PS I did everything else, remove battery, disable signature, got scatter MT6582 + download agent for flash tool (also updated), tried with ADB but can't detect device (of course it keeps deconnecting :silly: )

even if you have mediatek usb vcom driver or adb drivers else original driver it works on all with the button press.
but set the setting like I said USB support normal without battery W/O and high speed.
don't set it to mediatek com ports on SP tool. but if you have mediatek com port change to port 20. that's what I did change the port com.

What version of SP Flashtool are you using?
Well I have tried everything everyone has said so far
No matter what I try I get
BROM ERROR: S_BROM_DOWNLOAD_DA_FAIL (2004)
[H/W] Fail to download DA to baseband chip's internal SRAM!
Have tried using both
SP_Flash_Tool_v5.1352.01
SP-Flash-Tool-v5.1532.00
Both do the exact same thing, tried checking the AD DL ALL with Checksum boxes, unchecked usb high speed and full speed. Pressing the down button before plugging it it, after. Nothing I do seems to work, in the device manager it just keeps appearing and disappearing over and over
I think a found the solution guys. After a sleepless night , I stumble into a russian forum who got the same problems as ours.
The correct version of the SP FlashTool we need for our device is the SP_Flash_Tool_v5.1348.01_SEC (http://mediafire.com/download/eaar07r2nm1v7t6/SP_Flash_Tool_v5.1348.01_SEC.rar). I read somewhere that it was because of the HTC Desire 320 has a security boot.
If you got a 4008 error, it's probably because you're using Win8-Win10. You need Win7. I'm installing Win7 on my PC right now, so I will tell you more about it later.
If you looking for the stock roms, I found this site : http://easy-firmware.com/index.php?a=browse&b=category&id=1449
If you speak russian, feel free to correct me.
Have a good one guys.

If you got a CID Error, it's probably because you have flash the wrong rom for your device. I didn't have to restore the NVRAM after this flash, but maybe you will have to.

Thanks for it, i've got that problem after trying to install custom recovery. I also got the error 2004 but i fixed myself by using DA_SWSEC.bin. Not sure if it work for ur guys or not.
I also learn that althrough HTC 320 is Mt6582 devices but we cant use the method they wrote in mtkrom site to install custom recovery. Now i can find the stock rom of my phone to check flashing custom rom via splashtool. I used telus rom above and i got problem wrong CID and the flash camera not work, if i have msg or phone call missing, it flashes like notice led! At least now my phone is working ok then. I'll try to contact HTC to get stock rom of my phone

Yeah I forgot to mention that, you need to use the DA_SWSEC on the SP Flashtool. What's your htc 320 model? Your probably have the wrong rom. The telus one is only for NA device.
EDIT: Are you using the HTC Desire 320 with dual sim: http://drop.ndtv.com/TECH/product_database/images/15201573649PM_635_htc_desire_320.jpeg
If this is your device, the Telus rom is not for your device.

usb otg suddenly isn't working anymore on my G4. so i figured a factory reset could fix it but to no avail. my last resort is to use LGUP and flash v10c but the problem
now is that my computer (windows 10) and may laptop (windows 7) won't detect my G4. but when i connect my S3 it works just fine. is there any fix on these? already tried uninstalling and re-installing usb driver.
please help!

but i havent flash any rom on my g4 as my unit is bootloader locked
also, i have tried usb host check app with the results as follows.
android.hardware.usb.host.xml
ok
handheld_core_hardware.xml
USB host not enabled
tablet_core_hardware.xml
not found
could the missing xml's be the culprit??

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!
