LG G3 is bricked, unable to turn on, and Code Error 43. NEED HELP ASAP!

So....... my LG G3 had a new OTA update for T-Mobile and I was an idiot to download and install the Update(YES I WAS REALLY DUMB TO DO THAT). So when my phone restarted, it automatically went to TWRP and I couldn't boot to system. I tried everything from hard reset to fiddling with the settings. When I attempted to turn on my phone, it wouldn't turn on even with charging the phone, using the buttons, and especially when I plug my phone into my computer. It gives me Code Error 43( Unrecognized USB Device) and now I'm in a hellhole attempting to fix this device by tomorrow. I need help ASAP before I lose my mind
P.S I'm rooted with Purple Drake and using ZoneROM

Can you boot into Download mode ? (Device turned down hold Vol Up then plug in to pc)

Nope. Can't even turn on the device and keeps on saying error 43. PLEASE SOMEONE HELP ME OUT OF THIS NIGHTMARE

Try to plug it on another usb port. And when you try to boot into download mode nothing happens ?

Yep! For two hours straight and I have all the drivers downloaded. Drivers worked perfectly until it turned off.......
I hope it turns on before tomorrow. Keeping my head up until it is fixed

http://answers.microsoft.com/en-us/...cognised/6a2a5531-8b80-4798-9aa6-ee2dcb705c7f
and if that doesn't help try to uninstall that Unknown Device from your device tree in Device Manager and install the drivers again.

That didn't work either. I believe its my LG G3 because I was fiddling with the "SD Card Partition" and it had an System Fat32 error and it shut my phone off completely and now it won't turn on after that. Is there a way to reset or reverse my Partition settings?

Update: The phone is charging on my portable charger but won't turn on nor connecting via Windows 8.1

I found the problem. After doing some research, my phone is being half brick and im using Qualcomm HS-USB QDLoader 9008(COM3) but I don't know how to push files or how to use qhsusb_dload on the LG G3. PLEASE HELP ME

I've never seen a device that doesn't boot into Download Mode.
So you're doing everything exactly like this man does and on 0:25 you can't see that Download Mode icon ?

Nope not working at all, either its trolling me or its officially dead. It just says im still ported into Qualcomm on my screen instead of download mode

Please help guys, I really need help before tomorrow. No boot, no screen,no download mode, no usb connected except for qualcomm hs-usb qdloader 9008 (com3) and can not use lgflashtool. Does this means its a hardbrick and I can't do anything to unbrick this device and I need to call T-Mobile for another phone or can the dev gods help me fix this phone problems soon. Please answer asap

U said, u fiddle with the sd card partition which I think shouldn't do... Best option is to take back for a replacement or repair my friend...

Thats the only option? I heard there is another way to reset it

I had the same problem .. I tried to update my phone with ota and the same happend to my phone .. I downloaded the latset stock software it was .kdz and i used lg tool and from control panel i changed the port to 41 and it did work

Put the phone into download mode, go into device manager, ports(COM), you should see LGE then right click on properties, Port settings, advanced, then change COM port 41.then click ok and you should be fine.

It has to be similar to this but I dont think the LG G2 variant would work on this and forgot to mention the usb is called qhsusb_bulk

Hard Bricked G3

Hi,
I was trying to flash a stock rom on my LG G3, but the flash blocked at 5%, so i rebooted the phone, and now I haven't the possibility to acces at the download mode or recovery mode.
and when I try to go in download mode, my computer show my G3 at QHSUSB_BULK.
Any help here? please.
Thanks you guy's.

Try LG boot repair tool I think its name was something like this...you can find it on there web page.

http://forum.xda-developers.com/sitesearch.php?q=QHSUSB BULK

I already made a search hack14u, and I found only soft for G2 or Samsung phone.
I don't find LG boot repair tool too.
I think there is no solution
edit : I can access to the Factory Reset screen, if I say no or yes, I come back to "Secure booting error ! cause : boot certification verify " with the LG logo.

Shut device down completely(Remove battery if you can't do it with button). Then press and hold Volume up and plug usb cable while connected to computer, that's how you enter download mode, did you do that and it didn't work?

Yes it didn't work, computer recognize it as Qhsusb_bulk.

LG PC Suite has an option somewhere in the menus to reflash-restore firmware, there should be something like Repair recovery or something like that, don't have the program right in front of me sorry Make sure you have installed drivers from previous post that I linked you, make sure that it's recognised in windows device manager. If this still doesn't solve your problem then the repair is much more complicated / difficult, needs jtag **** = getting stuff from it's motherboard etc, there are some guys that do that all over the world but it would be better if you send it to your provider or from where you get it for a repair service/ replacement ( if you still have warranty ).

Tomorrow I will try to find this option in LG PC Suite. If I need JTAG, it's better to send to LG for repair, yes luckily I have the warranty.
Hope he don't make me pay for that. I gonna say a official upgrade goes wrong or something like that.
Thanks for your response !
Happy new year
Edit : I tried the option in LG PC suite, and the sfot doesn't find my G3. So Tommorow I gonna send my phone at LG.
Thank's for your help

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

LG G Pad v480 (8.0) hardbricked...

Hi guys,
You're my last hope haha.
My new lg g pad 8.0 is totally bricked, like no screen at all, no fastboot nor download mode, only an unknown device in Windows Device Managers saying "QHSUSB_BULK".
I really don't know what to do since it's the first time I encounter that kind of thing.
Thanks for your help/time !!!
EDIT: For those that can help : Qualcomm 9008...

Getting computer to recognize
I'm in a similar predicament with my LG GPad 7.0 V410. No display, no fastboot, no adb, no recovery. I seem to learn about things better when I royally screw them up first, lol. Anyway, I spent hours trying to get my computer to recognize it. Finally as simple as it is, I removed it from my computer, held down the power button for 20 seconds, released it, then plugged it back into the computer while holding down the volume up. Like magic my computer recognized it! I guess it just needed to reboot. It is now recognized in Device Manager as Qualcomm HS-USB QDLoader 9008 (COM2). Now from what I understand this should give a platform to flash it from scratch but so far I'm stumped. I've been playing with qpst lg flash tool etc.. I really don't know what I'm doing at this point. But since its in a Qualcomm state and not an LG state, I reckon you should be looking at ways to interface with the board inside Which is the MSM8226 (same as mine). Hope that helps! I'll keep you posted if I get anywhere. What is challenging for me is the stock LG firmware kdz for V410 is no where to be found.

Fantastic news!! I have finally come up with a solution! My tablet is back up and running!! I've posted a tutorial, it's based on my tablet but again since we share similar hardware should be able to help you as well! You'll just need to locate the appropriate KDZ (stock image). Good Luck let me know if you any questions or if you need help finding your kdz. http://forum.xda-developers.com/android/development/qd-9008-fix-tested-lg-v410g-pad-7-0-att-t3269057
